Pretty plain and simple.
Centroid extraction of Revit elements (applicable to Generic models and such)
Asked for in forums (problems) since 2012..
Dynamo as a coding language is too buggy, it requires a perfect set of solids, it is rather impossible in most cases because sometimes these intersect a lot.
If AutoCAD can do it it is unbeliveable Revit can't. AutoCAD has too many steps in getting the results and doesn't include density (mass=volume).
GRAITEC offers this but their support is bad, and 700 euros per year only for centroid function just because Dynamo is a weird perfectionist... no thank you. Same goes with Inventor which is not even a part of AEC.
Think about this guysssss... think about it.
Thanks
