Hi @JulienPoivret,

I am not sure I understand the question, Is it that you want to convert a bounding box to a Brep box? And then add the Brep box to the document?

simply adding the ON_BoundingBox object type to the document ?

Hi @JulienPoivret,

The Rhino document does not store bounding box objects. You see, ON_BoundingBox does not inherit from ON_Geometry.

So what are you trying to do and why?

ah ok, then maybe converting the ON_BoundingBox object into On_Brep and adding it to the doc with context.m_doc.AddBrepObject()?

what i want is select an object and get its bounding box for further boolean operation…
how to get a brep from an ON_BoundingBox object then ?
thanks for your help;

Here is a SDK sample you can review.
