From a customer, answered by my co-worker John:
Q: I want HydraCAD to fab a consistent 0-2” nipple for all of my Riser Nipples. I know the cut length will vary depending on the pipe it is attaching to and I am having to insert Riser nipples on grid lines, armovers, and mains and guess at the different C-C lengths as I insert them.
A: AutoList looks at the fittings at both ends of each pipe and applies the appropriate takeouts based on the Fitting Instruction Groups (FIGs) used. One way around this is to insert ARMOVER overrides at the top of the riser nipples by using the Override (OV) command from the Listing toolbar. The ARMOVER override is found in the Elbow category.
This will separate the riser nipples out of the branch lines and into the ARM1 Section ID in HydraLIST. In HydraLIST change the quantity of the 0’2 pieces to the total number in the quantity column of the ID and delete the other entries.
If the text of the riser nipple is visible on the drawing and you would like it to reflect the cut length you chose, then use the Manual Cut Lengths (MCL) command on the Size Pipe flyout of the Piping toolbar.
