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.
