Hi all,

I am trying to find the start and end points of the analytical lines in Revit. I am trying to transfer to analysis software however to avoid modelling inaccuracies I would like to use the analytical lines rather than curves/lines on structural framing for example. I haven’t been able to find any nodes to do this, is there a way to do it via using Python?

Cheers

No python required. How are you selecting your elements? By analytical category like this:

Or if you’re after something that catches more of the elements, you can use the same all elements of category method in combination with this little gem in the excellent MEPover package:

That’s one of the first lessons I learned about Dynamo: Python probably isn’t needed.

I hadn’t thought of using the geometry node. I’ll give it a try tomorrow. Thanks!
