Using the Hydratec Software Download Area

Hydratec uses ShareFile to distribute our software installs and updates. New customers, or those without access, must request access to be able to get at these downloads. Access is only available to customers with a Hydratec subscription or those on an update plan.

You can access the download area and request access by picking the Sign In link at the upper right corner:

Requesting Access

An account must be created in order to access updates and installs. After picking Sign In above, you will see a graphic for ShareFile Software Downloads. The request access link is at the bottom of this (circled in green, below):

Select that, and you will be brought to the Software Request Access Form:

Complete this form and pick the Submit Request button at the bottom. Access will usually be granted within 36 hours - if your company is eligible for such access, as explained earlier in this post.

If you use an email address that is not known to us (such as a non-corporate address), however, verification may be further delayed as we check to see if your company can verify your employment.

You may have more than one user whom you want to be granted access. Just have each one fill out this form. Also let us know if only one or two specific users are to have access so that we may block other users who request access. When access is granted, you will receive an email stating such. You may then use your email address and password to log into the subscription fulfillment system by using that same link.

Logging In

After picking Sign In (and assuming you are eligible for access), you will see a graphic for ShareFile Software Downloads. The sign in button is blue, and is circled in green, below:

This will direct you to our ShareFile log in page. Enter in your user name and password. If you forget your password, use the ‘Forgot Your Password?’ link below the login.

Note: Accounts that have an amount past due may find their access suspended. Please contact us if you see folders that tell you to do so.

Once you are logged in:

Instructions Folder

Once you log into the subscription site you will see the ‘Instructions + What’s New’ folder. This folder contains, the What’s New document and other documents that support using this system, as well as informational documents that apply to customers in general. The What’s New document includes a list of the last 12 months of updates, installs, data, documentation and videos, along with the folder locations of those items.

Software Folders

You will also see folders for each software package that you have a subscription for. In that folder you will find sub-folders for Installs, Updates, and Documentation. You may also see folders for Videos and Data. 

Each folder has at least one document explaining the contents of the folder, and/or specific instructions for the proper installation of the files within that folder. Please read them, as they are necessary for the proper updating of the software.

Data downloads could include complete data updates of new pipe types and fittings for hydraulics and new part numbers for HydraLIST, for example.

Redefining Blocks

So, you have a situation where you have a particular block in your drawing, and you want to change the block and have your drawing updated with that new block. If you don't have that block already defined in your drawing, or you can purge it out of the drawing, then you don't need to do anything, just insert the new block.

But, if it is already there, and you again insert the block, AutoCAD does not look on the hard drive for a copy, it looks in the 'Block Table' of your drawing, for efficiency. So, you need to force AutoCAD to look at the new block from the hard drive.

This is how that is done:

1 Change the block as you see fit. You can do this in your 'master' drawing and do a WBLOCK to export it, or you can edit the block directly, as 'blocks' are no different than any other drawing.

2.Then, Type in CLASSICINSERT at the AutoCAD Command Prompt. That brings up this dialog:

3. Pick the Browse button and steer to the folder where you have the new version of your block and select it. - Note: you MUST pick browse and reselect the block, even if the correct name is already in the Name: field. This forces the redefine.

4. Pick Redefine block – this will replace all existing instances of your block, while retaining any attributes you may have

Using HydraVIEW to Print a Pump Curve

From a customer:

Does Hydra Cad produce a printable fire pump curve graph?  I have some fire pump results and they are wanting a graph.

This question probably arises because the HydraCALC standard Water Supply Graph does not show solely the Pump curve when there is a City and Pump inputted, for clarity sake. It only shows a combined City Supply and Pump Curve. If there is only a Pump inputted, then the Pump Curve will print, but the Water Supply Graph might be too cluttered for some, and they only want to see the Pump Curve.

Fortunately, there is an easy way to do this using HydraVIEW.

Open HydraVIEW.

Pick the Tools dropdown menu and then pick Draw WSC (Water Supply Curve)

This will bring up the following dialog box:

As you can see, there are three options. The first is the most common one - drawing a standard US style water supply curve. The second will draw a pump curve from a hydrant test. Pick OK with the first one selected.

This displays the input screen for a custom water supply curve. Notice you can enter the information concerning all aspects of the multiple curves that HydraCALC prints on the water supply graph

Here we will concern ourselves only with the pump curve

NFPA13 Conforming Pump

For a standard NFPA13 pump curve, we would input information into the Pump area. Below, I have entered in the information for that pump, including the Rated Pressure, Rated Flow, Churn percentage and Elevation of the pump, in feet.

I have also entered in a Project Name and a Page Number for this graph, so I can add it to my regular printout.

Picking OK will result in that curve getting generated:

Non-NFPA13 Pump or Pump Test

If you want to print a pump curve for a pump you have run a test on, or it is a pump that does not conform to NFPA13, you can use the Advanced button to create that pump.

Put in the results of your pump test to create a curve.

Lastly, notice there are button to save this curve and load it again for another job. The Zero Data button simply clears the entries in the dialog box.

Saving, Reading and Matching the Top Five FIGs in Drawings

From a customer:

"Now that I freelance for several different clients, I run into some issues with AutoList. I have to change a couple of the Top Five FIGs each time I bounce between clients projects, as I only stocklist as they request piping to allow for any building or coordination changes.

This causes issues when I have to go back to a previous project as the Fitting group info is not drawing dependent."

But it is drawing dependent! 

The Top Five FIGs are saved in the drawing when you run AutoList. If you haven't run AutoList at least once, then they aren't saved.

Further, you can read the Top Five stored in such a drawing. And, you can set your current Top Five to match those of the drawing you just opened. Here's how:

Go to the Top Five by using the Choose Fitting Groups button in the Listing Tag Setup dialog or through Fitting Mapping. On this dialog are the buttons we are referring too:

Read Drawing FIGs will display the stored FIGs in a text file

Match Drawing FIGs will display the stored FIGs and then 

In the future, we will add a Write Drawing FIGs which will record the current FIG setup in the drawing without having to run an AutoList. This way you can make templates for each customer you have and use Match to align the two.

Listing Two Sides of a Branch Line Under the Same Listing ID

If you want to have only one branch line ID for an entire branch line, but are worried that AutoList will absorb other fittings into that branch line, or will miss certain sprinkler heads because of the default way it does things, then this is how to set things up properly.

The part I mention above concerning missing sprinkler heads is this:

Listing tags do not pick up fittings and heads that coincide with their insertion point. They can only ‘see’ ahead of themselves, not behind them, nor can they see what is directly underneath them.

So, the sprinkler head in the following image will not be picked up in AutoList due to the fact that the listing tag is at the same point as the head itself:

What to do?

The solution in this case is to insert two listing tags at the top of the riser nipple, each pointing towards a different end of each line. So, you would put one listing tag at the end of the pipe near each coupling near the top of each riser nipple, resulting in each one pointing to another branch line end.

This will normally result in each side being listed with a different numbers, but there is a way to keep them the same.

In order to get both sides of the branch line to list under the same line number, you can tag them by choosing Many in the Start Points section of the dialog. Secondarily, you will make the number of Start Points be 2.

You will then be asked to pick each of the two pipes, and then asked to place one identifier.

 

Creating a Revit Model with HydraCAD for AutoCAD

This ability has been in HydraCAD for AutoCAD for at least 10 years. You can draw a 'regular' HydraCAD system, and then create the Revit model for coordination with the BIM team on a project.

This requires a few things:

• You must have Revit on the computer using the HydraCAD for AutoCAD in order to make the conversion
• You must know the version of Revit that the BIM team is using to coordinate. Each version of Revit is different, unlike most versions of AutoCAD
• It is helpful to know the 'common point' that is being used by the BIM team to line up the models provided by each trade

If you have HydraCAD for Revit, then great! Because then you are actually drawing in Revit and don't have to do anything.

 

Lining up the HydraCAD model with the 'common point' of the BIM model:

Step 1: From the Collaborate toolbar, pick the command named Move Model:

Step 2: Pick Denote Basepoint. Select the ‘common point’ the BIM team is using.

Step 3: Pick the Move Model button to make the move. The drawing won't look any different after using this command.

 

Generating the Revit model:

Step 1: Elevate your drawing to 3D.

Step 2: Pick the Create RevitLink command from the Collaborate toolbar:

Step 3: Pick the version of Revit to go to and pick the Generate button

Step3a: If you get any errors such as this, below, pick the Delete Elements button. You may have to pick it once for each error

Step 4: Pick Launch Revit MEP

Step 5: Once Revit is open Pick New from the MODELS portion of the menu

Step 6: Make sure Create new is set to Project, not Project template and pick Browse from the Template file selection. 

Step 7: Browse to the C:\HES\Hydratec for Revit\Data\Families\20## folder, where ## if the version of Revit you are generating the model for

Step 8: Select the HydraCAD-Imperial_Default.rte (if using US unit system) or HydraCAD-Metric_Default.rte if Metric

Step 9: Pick OK

Step 10: Pick Save to give your project a name and location

Step 11: On the Addins tab, select the Retrieve HydraCAD Revit MEP Content item from the HydraCAD button

Step 12: This will begin Step 2 of the conversion process. This process will take at least a few minutes to complete. Maybe 10 to 20 or more

Step 14: After the conversion is complete, you can save and send the .RVT file to whomever you want. If you want to view the fire sprinkler piping, use the Project Browser to select Views – Coordination – Fire Protection – 3D Views – 3D Fire Protection

Step 15: This will show the model that was created. Each element and head has been given information as to its type or manufacturer. Save this model and share it with the BIM team

Generating BIM Models for Revizto

Revizto is BIM software that competes with Autodesk's offerings, specifically, Revit. Revizto can open HydraCAD drawings, but some information may not be showing up properly. These two HydraCARD Knowledge Base entries should help you get by the issues we most often hear about:

When reading a Persistent Model drawing in Revizto, the units are not correct

-and-

When importing a Persistent Model into Revizto, none of the riser nipples are visible

 

Alternate Part Numbers

HydraLIST has the capability to store an Alternate Part Numbers for each HydraLIST part, along with our standard part number. Why is this important? Because many fab shops, either independent or sprinkler company based, already have their own part numbering scheme. This ability allows our customers to continue to use their own part numbers when referencing our parts, assemblies, pipe types, hangers, etc. So, they don't need to start from scratch and build everything over again.

In the HydraLIST database (accessed via the green circled button), the input screens have a column for such Alternate Part Numbers:

The first yellow highlighted column shows our PN and the second, the Alt PN. Just enter in each alternate part number and save the data and you are done.

When it is time to print out a stock list, there is an option to print the Alternate Part Number on the General Setup tab:

Please check out the HydraLIST manual for complete details!

Importing Parts into HydraLIST

As new products are released by manufacturers, we add them to files that can be imported into HydraLIST. Why don't we add them to the HydraLIST database directly? Two reasons:

1. We don't want to overload the database with thousands and thousands of items that may not be used by most of our customer base
2. Many customers customize their databases, so they do not use our updated databases anyways

So, we create Import files. These Import files are added to HydraLIST updates and installs at periodic intervals.

Here's how to use them with such a new file for Victaulic UMC valves, for example:

 

Step 0: Copying an Import file to your computer (not necessary if said file is already there due to an update)

If we send to such a file, put it in the relevant folder, or ask us for advice. For example, I sent a customer an Import file for Victaulic's UMC valves. I told them to put it here:

Note the folder structure. Put the file where it makes most sense to put it. It is not critical that you select a particular folder, but it helps to have it in the folder that makes the most sense.

 

Step 1: Entering the Database to Import the parts

Importing parts into HydraLIST is done using the General Data button in HydraLIST:

That opens up our database entry program.

 

Step 2: Importing the parts

Pick the Import Data button:

This brings up the folder structure referred to in Step 0. Go into the folder you expect to find the part file. In this example, I am selecting the  4-Valves_Accessories folder and then the example file: Vic_UMandUMC_4V32_20240122.txt

In this example, I am selecting the  4-Valves_Accessories folder and then the example file: Vic_UMandUMC_4V32_20240122.txt. Pick the Open file to bring that data in

The data screen will show all the parts contained within that file:

 

Step 3: Saving the imported data

You must save the added data or it will not be there when you search for it later. Pick the Save Spread Sheet button

Step 4: Pick the Project Data button to finish updating the new database. when asked if you want to create a backup of the database, we suggest you pick Yes

Step 5: Searching to ensure that the parts made it into the database

Switch to the Miscellaneous tab. Type in a few letters from at least one part description that you imported, into the Part Number Search field. In this example I typed in UMC. Pick the Find button right under that entry. All items containing that string should appear in the currently selected Section ID

Note: If you find there are parts we do not have, but you use frequently, or you are looking for new parts released by manufacturers, please contact us and we can get those to you.

Managing DefLine Polyline Widths

Customer X called today to ask if he could reduce the width of the polylines that are part of our DefLines (Drop Windows, System Boundaries, AFF/BTS, etc).

There is no setting in our programs to do so, but there is an easy way to change them after the fact. After some chatting back and forth the answer is to use Select Similar and the Properties box to change these to the width he wanted.

Select Similar is a great tool added to AutoCAD a few years ago. You select an object like a line, a polyline, a block or text or whatever. You then right-click and pick Select Similar from the right-click dialog box. All objects that match that object will be highlighted. If you pick a line, then all lines in the same layer as the one picked will be selected. You can change the things Sel Sim considers similar by using the SE option inside the command.

So, to change the widths of our DefLine polylines, pick one such defline and right-click. Pick Select Similar

You will notice all such items will be selected (highlighted). Now, pick Properties:

Locate the constantWidth specification in the Geometry section and type in what you would like the new value to be. Close the Properties dialog and you are all set.

You can do the same with Ceiling Height boundaries, System Boundaries, and the like.

Converting Text to MText

So, my co-worker (who shall remain nameless) sent me an annotated drawing with notes on how to properly model trapeze hangers for coordination. The notes were written as individual lines of text. This annoys me:

I like working with MTEXT so much more. MTEXT allows for formatting, fonts, underlining, numbering and more.

I thought I remembered that there was an Express Tool in AutoCAD that will convert TEXT to MTEXT - and, there was!

It is here:

It lets you grab any number of lines - these will be converted into one MTEXT object.

After some editing:

Fitting Lengths in HydraCALC - Why don't they match what's in the database?

This from a customer in Sweden (paraphrased). This in metric, but the math is the same in US units:

On the Fittings Used Summary, it says that a 65mm Tee has the equivalent pipe length 3.8m but in the calculation says 7.497m. And it´s the same for a 65mm 90 degree screwed elbow...the equivalent pipe length says 0.88m but in the final calculation on page 4 it says 1,736m

Why are these numbers different? And how can we change so that they are the same?

The answer lies in NFPA (where else?).

Paragraph 22.4.3.1.3.1 of NFPA13:2010 states that for internal diameters other than Schedule 40 steel pipe the equivalent lengths given in Table 22.4.3.1.1 must be adjusted according to the formula given in that paragraph. The next paragraph (22.4.3.1.3.2) states that this new value must be further adjusted by the C-Factor if no C=120. Fittings whose values are supplied by a manufacturer that has already adjusted them do not need to be further adjusted.

These two adjustments change the equivalent length stored in HydraCALC's Pipe/Fittings data. So, these two calculation reports the customer is referring to often display different values.

This can be turned off, however, for those jurisdictions that do not require such an adjustment, or for fittings that have already been adjusted by the manufacturer.

When the job is calculated, you can deselect the Auto Adjust Fittings Lengths option. This will give you the stored database values:

This option resets itself with each calculation, but you can turn that option off by default by using the Edit User Options tool in the Options drop down menu:

Set the Auto Adjust Fittings option to False

This adjustment can also be blocked when inputting new pipe and fittings into the Pipe/Fittings data. The highlighted column is named Y/N Mark. An 'N'' means to not adjust the fitting as mentioned above. This is most prevalent with CPVC fittings, as the manufacturers publish values that take the pipe diameter into account.

More Than 200 Passes Error in HydraCALC and Using the Find Disconnect Tool

Occasionally users may get a 'Job has gone 200 or more passes without balancing." error message. This means, usually, that there are disconnected pipes in the job (pipes that may have flow in them, but do not connect to the piping between the Remote Point). You can try picking Yes to have it continue to try, but that usually doesn't work to resolve the situation.

Take a look at the calculation below. If you look long enough, and trace the piping, you can see what wrong.

In a bigger job, however, that can be difficult. But there is a tool to help.

In the Utilities dropdown menu, the tool is Find Special Disconnect

Select it, and you will be given a dialog with a few options. Select the Show Disconnected option and then pick Find Disconnects. This should notify you of the 'orphaned' pipe. In the capture below, it appears a block of piping related to reference point H and reference point I is a bit adrift.

Another tool is the Show Potentials option. Selecting that gives a list of nodes that might need to be connected to the rest

Picking the Highlight Potentials button displays this graphically, to help you see better where the piping in question lies.

Adding a pipe that connects G and H will resolve the problem.

Note: There are other reasons to get the original error, but our programmers have resolved a few of them, so they should not present themselves on your machine.

 

Managing the HydraCALC Database

We regularly update the HydraCALC database to add and make changes to fittings, pipe types, valves, backflow preventors and technical data sheets in PDF format for all of these.

We make this database available for download in the Customer Support area of our website, which can be found at www.HydraCAD.com. Enter the Customer Support area by picking the Login button at the upper right of our home page. Then, navigate to the folder seen below by selecting HydraCALC, then Complete Data Update

Download the .zip file to a location on your hard drive. Then, extract the contents to a new folder on a drive. Then, run the SETUP.EXE to install the new data.

Note that this will replace any changes you may have made to our database. So, you may want to keep a copy of your changes so that you can reapply them. Or, simply request that we add the items you may have modified to our regular database, and that way you will not have to worry about that.

The key database file which users may have modified for HydraCALC is Master.DAT which resides in the \HES\HydraCALC\Ver50\Data\Setup folder. This file contains all your pipe, fitting and valve data and is well worth protecting. This file is automatically backed up when you run the Complete Data Update, but we suggest that you back this file up whenever you make your own changes and keep the backup in a distant and safe location.

Viewing a Simplified Revit Model

From a Customer:

"We’re engineers. As such our expectations for plans are a little different than installers. We need to use clear, consistent 2-dimensional symbols and simple lines to represent pipes without fittings. Right now all of our projects are showing top-down 3d models in plan view and every single pipe fitting. This makes it challenging to review the components for ourselves and our jurisdictional reviewers.

Is there a function we’re missing that would allow us to simplify the plan views?"

There is:

Each view in Revit has three (3) potential detail levels. The detail level button is here:

Detail Level FINE

 

Detail Level MEDIUM

Detail Level COARSE

How Listing Tags Work to Determine Stocklist Entry Order and Type

Previously I mentioned Listing Order. This post takes things up one level to discuss just what ends up where when a job is AutoListed.

From the HydraCAD Manual / Electronic Help:

It is important to understand how the Listing tags work in order to achieve a successful AutoList run. There are two types of Listing tags. One for welded pipe (mains and welded branch lines) and one for non-welded pipes (threaded or plastic lines.)

The Listing ID for a main usually begins with a space followed by a letter. This is noted throughout this chapter as _A (Space A) wherever such a main ID is used. The green line before the A in the above picture represents this idea. The 01 in the above image represents the zeroth (0) fabrication method (first of five FIG Groups, set through the Listing Tag Setup dialog) followed by a 1 which means Welded.

The Listing ID for a line usually begins with a number. The 22 in the above image represents the second (2) fabrication method (third of five FIG Groups, set through the Listing Tag Setup dialog) followed by a 2 which means Threaded.

You cannot have two Listing tags with the same Listing ID whether they are mains or lines. The AutoList program will detect Listing tags on your drawing and begin to gather information in the direction that the Listing tag is pointed. The direction that the tag is inserted is  the direction you want the listing to be done, usually the direction of the water flow in the system.

You may be able to stocklist a threaded sprinkler system with a welded main by placing a single Listing tag at the start of the system piping. You can also divide the system into listed areas by inserting multiple Listing tags and using Stop Signs if necessary.

When a main is tagged, the listing program will travel down that main until one of four things happen:

1.       It runs out of main. In real life, the main usually runs out at a cap.

2.       It encounters another listing tag on the main. The first tag is usually pointing in the same direction as the next tag encountered.

3.       It encounters a Stop sign or Fake tag.

4.       All of the other pipes connected at a junction have already been listed. AutoList will not list anything which has already been listed.

When a line or riser nipple is tagged, the listing program will travel down that line until one of four things happen:

1.       It runs out of line. The line usually runs out at a sprinkler.

2.       It encounters another listing tag on the line. The first tag should be pointing in the same direction as the next tag encountered.

3.       It encounters a Stop sign or Fake tag.

4.       It runs into a main. It will stop here, since the mains are usually listed before the lines, and AutoList will not list anything which has already been listed.

The one thing that determines whether piping is a main or a line is the listing tag. Welded tags are usually associated with welded mains and welded branch lines. Threaded tags are usually associated with threaded or plastic/copper lines. If the lines are to be welded, they are for all practical purposes mains and should be tagged with welded tags. These lines should be drawn in the lines layer (SPRKDAT2). Note: Your choice of main and line numbers critically affects the order in which the stocklist is produced and reported.

Lines are normally drawn in SPRKDAT2 (yellow) and mains in SPRKDAT1 (white). This does not mean that things drawn in SPRKDAT2 can't be listed as mains; this is quite common when the "main" is 1 ½” inches in diameter or larger. When a main is drawn normally (SPRKDAT1), any lines connected to it will automatically be numbered, listed, and consolidated. These lines will be threaded. If the main is drawn in the lines layer, or if the line fabrication method is other than threaded, you must tag the lines yourself. Armovers (SPRKDAT3 green) are treated line threaded lines. Underground (SPRKDAT4 dark blue) are not designed to be listed by AutoList.

As a recap from the previous post on listing order:

Tagged welded piping always lists before tagged threaded piping. Within either type of fabrication, the naming of the tag further determines the order of listing. Numbered tags list before lettered tags. Lower numbered tags list before higher numbered ones (1 before 2). Likewise, lower lettered tags list before higher lettered ones (A before B). A space before a letter or number will make that tag take precedence over all others. A general rule worth following is to name the mains the lowest, the riser nipples higher and the lines the highest. Always use a space before a main identifier, and you shouldn’t have any problems.

Listing Order for Welded Piping

How does AutoList decide what order to list piping in?

Here are the general listing rules that pertain to the order:

1. Welded piping (whether lines or mains) lists before Threaded piping
2. Welded piping is listed in alphanumeric order (specifically, the ASCII order)

Per the ASCII order, numbers list before letters. Punctuation marks, including spaces “ “ list before either (because spaces come before numbers in the ASCII chart).

You want the mains to list first, then the welded lines and then the riser nipples.

Label accordingly using this scheme:

Label the Mains as such “ A”, “ B”, “ C” etc. notice the SPACE before each letter in those three examples. This forces the mains to list first.

Label the welded lines using a letter before a number, such as “L1”, “L2”, “L3”, etc.

Label the riser nipples using a letter before a number, ensuring the letter(s) used come after the letters used on the welded lines (RN comes after L), such as “RN1”, “RN2”, “RN3”, etc.

From the manual:

“Tagged welded piping always lists before tagged threaded piping. Within either type of fabrication, the naming of the tag further determines the order of listing. Numbered tags list before lettered tags. Lower numbered tags list before higher numbered ones (1 before 2). Likewise, lower lettered tags list before higher lettered ones (A before B). A space before a letter or number will make that tag take precedence over all others. A general rule worth following is to name the mains the lowest, the riser nipples higher and the lines the highest. Always use a space before a main identifier, and you shouldn’t have any problems.”

I will soon be posting about what rules apply to listing in general, as the order is only part of it....

Zoom Extents Leave You Out in Space? Some Strategies

We've all seen this. You have a nice drawing in front of you, but when you do Zoom Extents (or Zoom All), your drawing disappears and you find yourself floating out somewhere near the (ex)planet Pluto. You select all around outside of what you want to see and there is nothing there.

Sometimes you can zoom around out there and find a stray object and just delete and all is fine. Other times you can copy the 'good' stuff and paste it to another drawing. But what if that fails? The stray objects in question could be damaged entities, or text objects with null text, or blocks with nothing in them.

I had a customer send me such a drawing and after decades of just dealing with it, I wanted to dig deeper. I tried a suggestion whereas you do a Zoom Extents (ZE is one of our aliases) and then hit CTRL+A. This highlights everything in the drawing. The idea here is that you can then see more easily those things out in space, because they have an easy to see grip attached. This didn't work for me.

So I found another video with the right suggestion (from Autodesk no less), for me, for this drawing. This is the link: Erase Empty Objects in AutoCAD

This is what it says to do:

1. Type in ERASE
2. Hit CTRL+A to select everything in the current space of the drawing, seen and unseen
3. Holding down the SHIFT button, grab what you want to keep. This will remove them from the selection set Erase will act upon. The remaining objects may or may not be visible
4. Press Enter

In my drawing, out of 80,000 objects, 12 were erased. A subsequent Zoom Extents now worked perfectly.

Exporting to SprinkCAD FDT (Fluid Delivery Time)

HydraCAD has long been able to create a file that can be opened in the JCI/Tyco/SprinkCAD Fluid Delivery Time program. That program is required to open the exported file. Hydratec and SprinkCAD worked together to offer this tool.

The file can be created from HydraCAD using a process similar to AutoCalc. The following is from the HydraCAD manual and the HydraCAD Help file:

Note: The pipe to be exported must be sized. There must be a water supply, at least one flowing head tagged using the Operating Sprinklers command. The drawing should be raised to 3D before executing.

1. The menu command Create Tyco FDT File will create a file that can be opened and calculated in SprinkCALC with the FDT option. Select the command from the HydraTools->Tools->Export menu:

2. An informational message is displayed after launching. Press OK:

3. The below dialog box appears. If the drawing is not already elevated to 3D, pick 1. Raise Drawing to 3D. You will need to restart this command after the drawing is raised in this manner. If the drawing is already raised, pick 2. Generate FDT File:

4. This displays the AutoCalc Setup FDT dialog. None of the settings here affect this particular process, so just pick the Calc button:

If you get an error message, the most probable cause is un-sized pipes. You can cancel the process and size them; otherwise, proceed and fix those pipes in the Tyco program.

5. If there are no errors, the Save As dialog box will appear. Choose a location and give the file a name. The file will have the tych extension:

6. You will get a message stating that you are creating a new file and are given the opportunity to copy the header data from a file you have already created.

Select Yes if you have the Header Data already entered into an existing job.  Select No to open the following dialog box where you can fill in the appropriate information and press OK when you are finished:

7. A message will appear indicating that the file was created. You should now be able to open the file in SprinkCAD FDT:
