Dear Autodesk Community,
I am currently facing a problem in my python script that makes me despair a bit. I already solved the problem in Dynamo. No Issues here, but I am trying to speed up my dynamo script by transfering some processes into python. The script is supposed to give the middle points of the two smallest faces of a boundingbox. However it doesn’t work. Error message says "AttributeError: ‘Face’ object has no attribute ‘Evaluate’ ". I have already tried a few things, but nothing seems to work out, and I am bit helpless at the moment. Maybe someone can find my mistake?
I would appreciate any help. Thank you in advance
