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]

Looks like you might not be feeding a system type or element type, but rather an element and a system. Try getting the parameter value for ‘type’ for both before feeding along your list. also make sure you’re feeding a single system and pipe type for each before progressing.

Hi @jacob.small I’ve attached my script for your reference. Pipes from Line.dyn (26.0 KB)

I need to model pipes using lines, all I have now created is a line using “Point.By coordinates” node and “Line.StartPointEndPoint” node. [image] created Next is to use “Pipe.ByLines” Node from MEPover Package [image] I don’t know what the error is in the python script since I’m new to it. But I want to know two things: Am I doing the right way (using the snips above)? Is there an alternative solution to this?

from which package you have taken ‘curve from line’ node. pls share the link here or tell me the correct package name. thanks in advance

I´ve a similar problem. I read dates from an excel sheet instead. The thing is I have as a result “null”. Can anyone help me?? [Capture]

Just type curve.startpoint or else look in the geometry section, hope it helps

I keep getting null result. I am reading points coordinates to create lines, but even with simpliest line I get null pipe result. Can anyone clarify what Revit version and Dynamo are you using. I try several version with same results. NULL pipe [image]
