I need to know what screen space bounding box an object occupies.
Something like this:
Is there any way to know that?

Iterate over every point, convert it to screen space and take the minimum/maximum values of the

Thank you, Niklas.
So, for parametric objects, I will need to convert them internally to a polygonal object.
Mmmmmm, ok.

Hi Rui,
for parametric objects you can simply access the cache, see GetCache() and siblings in BaseObject API reference. You could also take a look into the new BaseObject Manual of the C++ docs, if you are not afraid of C++ code.
The functions for coordinate conversion Niklas mentioned are part of the BaseView.
