Hello, I`m new ussing the Autocad and Civil 3D API and I would like to combine a part of a python code to get the area of a group of surfaces (wich are not TIN Surface) with the Node SelectObejcts.
In the image, I have two Python nodes, The first one (Python Script(01)) is to select the elements in the drawing space and the second one (Python Script(02)) is to get the area from the selection group, I think the problem could be the ObjectId.
if someone can help me, I really appreciate
Let the files that I used below
Thanks
