From a customer today (paraphrased):
"I’m having issues with HydraLIST keeping my rod cut lengths to the ½” length I assign it even with noting it as “CL”. It wants to always round up to nearest inch. This is primarily the 06 hanger I’m using. Is there a setting that forces this rounding?"
The answer is yes, there probably is. It may be a default setting in the data we ship, or it may be a company setting your organization created.
To the point, some companies use studs instead of cut rod for inch or two-inch length up to a certain value, like 6" or 12".
The documentation that covers this is in the HydraLIST manual which can be accessed by picking the Help pulldown in HydraLIST. This topic can be found on page 7-223. In it we look at a Type 01 hanger, but the rules apply to the other hangers as well. Viewing or changing all setup rules in HydraLIST is done by accessing the General Data by using the button shown below:
This is what it tells us:
The Makeup of a Type 01 Hanger
In HydraLIST, pick the General Data button. Select the Assembly Table tab with Use Hanger Grid not checked. Pull down the Assembly Number list and select the 01 60 hanger. This is a top beam clamp hanger which is a type 01 hanger. The 60 in the assembly number indicates that it is a hanger for 6-inch pipe.
The list of parts for this hanger appear in the lower section of the screen. There are part numbers for a rod, a 1/2" beam clamp, a 6" hanger ring, and a part number for the labor required to build the assembly.
If center-to-center distances are selected in the Hanger Project screen, the rod cut length must be calculated. For this reason, this item must be entered in a special way. Under the Quantity column is the formula L-6. When the hanger list is processed, the computer looks up the center-to-center distance from the Hanger Project screen, and subtracts 6 inches from it for the pipe ring takeout. The length remaining is the cut length of the hanger rod.
If cut length entries are entered in the Hanger Project screen, then L is taken as the length of the hanger rod and no takeout calculation is performed.
Hanger Sub-Assemblies
Note the part number for the threaded rod entry. It is #1/2ROD. This is a sub-assembly which is used so that the correct rod part number may be pulled from stock based on a range of sizes. Any assembly which begins with a # is a sub-assembly.
View the #1/2ROD assembly by finding it in the Assembly Number pull down list.
This is the #1/2ROD sub-assembly which ships with HydraLIST. The Quantity field specifies the range of lengths that are valid for the job entry. If the entry falls within the criteria, then the third character is executed. For example, on the first line the Quantity characters are 0,99999999,L. This is interpreted as any rod from 0 inches to 99999999 inches (a very long length!) is to be processed and printed as the length (L) entered in the Project screen. Note, the criteria in this column must be separated by commas. If you wish to have your hanger rods listed to have lengths as entered in the Project data screen, then use this option.
With the first line present, none of the other lines are executed since the first line will satisfy any rod requirement.
If your shop prefers to use studs which are pre-cut to length, then delete the first line so that the subsequent lines may be used by the process program.
The next line, Line 2, has an entry of 0,2,1. This is interpreted as any rod from 0 inches to 2 inches long will require 1 of part number 6027005020 to be removed from stock for the job. This part number relates to a 1/2" X 2" All Threaded Stud.
Line 3, has an entry of 2,3,1. This is interpreted as any rod from 2 inches to 3 inches long will require 1 of part number 6027005030 to be removed from stock for the job. This part number relates to a 1/2" X 3" All Threaded Stud.
This selection of threaded studs continues until 6" is reached. At this point, line 7 is executed. Line 7 has an entry of 06,99999999,L. This is interpreted as any rod from 6 inches to 999999999 inches (also a very long length) is to be processed and printed as the length (L) entered in the Project screen with the part number 6027005000 which relates to 1/2" All Threaded Rod.
Notice that all of these rules effectively round the rod length up to the nearest inch (for this assembly). Others may go every two inches, for example.
Please refer to Chapter 7 of the HydraLIST manual for more details about this subject.
