Plane aligned box of 3D text

I am trying to get the bounding box of some 3d text that is not in world coordinates, but in a plane I specify.

Using .BoundingBox gives me world axis aligned.

I can’t use Box(Plane,GeometryBase) as the 3d text is not geometry?

I can’t extract corner points of the text to create the box myself.

Any help would be much appreciated.

Hi Hugh,

Let me know if this sample helps (or not):

Hi Dave,

If I understand correctly the simple approach is to work everything out in world coordinates and then transform back to the plane I am interested in? I was hoping to avoid having to, but it won’t be too much of a chore to implement.

Thanks for the help.
