This is probably and old topic sorry. I’m completely new to Dynamo so yeah, I copied some nodes without have one iota what it supposed to do or what value it needs I’ve tried a couple of scripts I found on this site and I can’t get them to work. I’m on Revit 2022. Walls2 I got 2 errors, for List.GetitemAtIndes = Warning: List.GetItemAtIndex operation failed. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Wall.ByCurveAndLevels=Warning: Wall.ByCurveAndLevels operation failed. Value cannot be null. Parameter name: curve. Walls3.dyn just died with message “Can’t make wall”, it did draw a bunch of crazy lines on revit. [walls2] [walls3]

@David125 [image] Create Pipe by Line (dynamo) , how? Developers Hello, so my script works without error i have my lines pipes a system a.s.o. [grafik] but it resulted in cero , whats way out? the pipes first need to be connected, the should be place line by line… or have i to filter out line which are too short. KR Andreas PyDWGSetPipe.dyn (21.0 KB) check out this topic… it should work for line based elements like walls

While the OP is over 4 years old, I would never use autocad files as a basis for creating Revit elements. You’ll end up with so many “slightly off angle” warnings for a start.
