BoundingBox.Transform not work

BoundingBox.Transform not change internal data, while transform.TransformBoundingBox work well.

boundingBox = transform.TransformBoundingBox(boundingBox);
bool result = boundingBox.Transform(transform);

Rhino version: 7 SR13 (7.13.21348.13001, 2021-12-14)
Nuget “RhinoCommon” version:7.13.21348.13001

@dale , Would you please have a look at this?

Hi @RyanZhou,

This seems to work as expected:

import Rhino

min = Rhino.Geometry.Point3d.Origin
max = Rhino.Geometry.Point3d(5, 5, 5)

bbox = Rhino.Geometry.BoundingBox(min, max)
print(bbox)

xform = Rhino.Geometry.Transform.Scale(min, 5)
bbox.Transform(xform)
print(bbox)

What am I missing?

Thanks,

– Dale

Dale, thanks for your reply. After checking code, I find that I make a mistake and there is no problem with api. Sorry for that.

BoundingBox is struct, instance’s property return a copy of it, anything changed will not affect origin value, below is demo code.

class XXXClass
{
    BoundingBox BoundingBox { get; set; }
    
    void XXXFun(Transform transform)
    {
        BoundingBox.Transform(transform);
    }
}
