Dear,All

I would like to change the Radius of the Cylinder.
However, it seems that only properties in Properties can be changed in the Python API. Is there a way to change the Radius?
Or, can I create a new cylinder by reading the Radius value?

Hi,

you must first check, whether your BRep is a cylinder. Use IsCone for that, as a cylinder is a special type of cone. This function gets you the placement, radius and height, so everything you need to create a new cylinder geometry to overwrite the old one. Here's an example of increasing the radius by 200 mm:

        is_cone, placement, bottom_radius, top_radius, height = old_cylinder.IsCone()
        if is_cone and bottom_radius == top_radius:
            new_cylinder = AllplanGeo.BRep3D.CreateCylinder(placement,bottom_radius + 200,height)

Best,
Bart
