Hello there,
I've made a visual script to try and get the gravity center but get error every time (cf pictures) and i don't know what to do to resolve the issue. If you have any idea i take it !
Thanks for answering
Hi
Here a starting point for your script (ALLPLAN 2025)
The idea is to select by mouse the objects, then I made a filter based on the geometry (I made it in Python, maybe can be done with nodes....)
import NemAll_Python_Geometry as Geometry
def function_to_execute(ele_list) -> list[Geometry.Polyhedron3D]:
""" implement the script code here """
polyh_list = []
for ele in ele_list:
if isinstance(ele, Geometry.Polyhedron3D):
polyh_list.append(ele)
return polyh_listThen Union and finally CalculateMass

The CalcMass-Node and also the underlaying function accepts only 3D-Solids, like Polyhedron3D, BRep3D and others shown in the message. You have obviously select a 2D-Line!
If you want the Centerpoint of the line, please use other Node to get it!
I need to find the gravity center of this 3D model what node should I use to get CalcMass to function correctly ?
Maybe filter the Elements with Geometry of Polyhedron3D or BRep3D first!
If I may ask: What is the point of gravity needed for?
Doesn't the center of the bounding box do the same thing?
I did try with bounding box but got the exact same problems.
I tried something else but i think i miss something (Cf video)
Hi,
Here an example
1) you select the objects
2) the script make an union of the objects
3) then it calculates the gravity point
Best

I copy what you did but i get : "Union: Attemting to append an invalid type"
Is it because I selected multiple objects or not ?
I tried with some 3D objects, but not with arch elements.
Can you post your drawing file with your objects?
I hope this is helpful
