Hi All, I’m trying to create pipes from line curves, but unable to create one. What I get is a null value. [image] Can anyone help me figure where the problem is ? thanks in advance

Figured out what the problem was. [image]

First of all, thank you for this node!! I was able to make it generate pipes from model lines, but I do not understand how to control which PipeType and PipingSystemType are used. I can make it select from the index, but it’s a blind selection. How I can I read that Watch list to know which index…

Just drop in a code block and type in: x.Name That will show you the names of the system and pipe type, then use the corresponding index number to feed in the correct type

Thank you!! That is an AWESOME trick!

Hi there – I’ve been able to get the lines to convert to pipes; however, where there were moments of the line turning 90 degrees, the pipes do not automatically add the fitting to connect them. Is there a way to add this function to the script? Or is it a manual process? Thank you! [image]
