[OSGeo-Discuss] Generalizing complex 3D vector polygon data

Here's my challenge. I have 3D buildings originally in the AutoCAD
format which are composed of hundreds of 2D polygons in 3D space.
Is there any tool that can "generalize" 3D data?
I found that GRASS GIS offers line generalization:
but found nothing regarding 3D generalization.
My feeling is that 'GIS technology' is just not there yet. There's just
no implemented algorithms to generalize complex 3D to less complex 3D
data. Am I right?
Since my team is heavily using FOSS4G, we're looking for a solution (if
any) that would ideally be 100% FOSS4G.
Thanks for any feedback,
