Sizing Mainline: Drawing Freezes During "Recursing Pipe"

Issue

You attempted to size the mainline in your irrigation design, and your drawing froze while "recursing pipe."

If the recursing process is simply taking an excessively long time, you may be experiencing a past bug that broke pipe segments when placing equipment on the mainline. If so, here's what to do.

Solution

1. First, check whether you've copied equipment in your system that was already piped.

If the Size Mainline tool is stuck recursing pipe, you likely have a high number of loops in your system. Lots of loops is a good indicator of copied piped equipment, as well as equipment that has connected automatically. See our Irrigation Equipment Connecting Automatically article for the solution. Once you've tried those steps, size the mainline again.

Is your drawing still freezing? If so, move on to the next step.

2. Type LANDFXDIALOGRESET in the Command line and press Enter.

3. You'll be prompted This will reset all Land F/X dialog box positions. Proceed? Click Yes.

The LANDFXDIALOGRESET command can come in handy when you're working in different monitors or when dialog boxes are hidden behind other windows. It locates all Land F/X dialog boxes that are stuck or hidden out of view and brings them to the front on the monitor where you have your AutoCAD window open.

4. Try sizing the mainline again. If it sizes correctly, you've resolved the issue.

Still stuck? Move on to the next step.

5. Update to the latest version of Land F/X and size the mainline again to see if that addresses the issue.

Still stuck sizing? Move on to the next step.

6. Do you have valve-in-head rotors in your project but haven't placed them in your drawing? Try placing one off to the side, or removing them from your project if you don't plan to use them.

Size the mainline. If it sizes, you've solved the problem. (If you placed a valve-in-head rotor and don't plan to use it, you can delete it from your drawing.)

Still no luck? Read on.

7. Follow our steps to clean your drawing and all Xrefs. Then size the mainline again.

Still freezing? Move on to the next step.

8. Finally, you can split your existing system into a series of smaller systems by deleting some mainline pipe segments. Try creating one smaller contiguous system or station, then size the mainline in that portion of your design.

If that works, continue creating additional smaller systems or stations and sizing them one at a time until you can get it to work.

While creating and sizing these smaller sub-systems, use our Highlight Station tool to select the mainline and see what is connected. If you've copied valves after piping to them, you can create a series of infinite loops, which can also cause this issue.
