Hi, I would like to create a script in spaceclaim that automatically creates a point at the centroid (center of an area) of a surface body (the surfaces are always planar in my use case if that helps).

1. Select surface
2. Run script and get a point at the centroid of that face.

What I have tried:
I have found the MeasureHelper class that has a method called MeasureHelper.GetCentroid that sound suitable. This method expects an object that implements ISelection. How do do I get an object that implements this?

Just as an update. I found the solution to this problem myself.

This script works like this:

1. Select the faces you want to create the centroid for (note: don't select the surface bodies)
2. Run this script:

Code:
# Python Script, API Version = V21

selected_items = Selection.GetActive().Items
for selected_item in selected_items:
    if not isinstance(selected_item, DesignFace):
        continue
    sel_i = Selection.Create(selected_item)
    
    pt=MeasureHelper.GetCentroid(sel_i)
    new_pt=SketchPoint.Create(pt)
