Wall by line code

Revit API
1

Rvtcad created a python code with help of ChatGPT and the Revit API which is a bit helpful for creating walls based on model lines. I am attaching images for better understanding.

Steps:
create the model line first
select the all model line
and run the code then it will work

Rvtcad scan to BIM 3D Revit wall created based on model line. Rvtcad serve MEP laser scannig point cloud to Revit 3D Bim model by Rvtcad

Try this code with pyrevit or revit python shell, i used a Variable Rvtcad which you can rename it :grin: :-
