Hi! i have been looking for a lisp that will delete any duplicated 3d Objects overlapping with each other in AutoCAD. There are many LISP that does this for 2D objects but i cannot find one for 3D. Please help

3d in Autocad are not native objects. They're results of 3d functions (subtract, union...). It might be possible (check entget) but seems VERY complicated.

You *might* get away with the ActiveX CheckInterference method using combinations of solids; if the volume of the interference solid is the same (+/-) as either of them then one should be fully inside the other. For complex models the iterations would be horrendous unless a pre-filter is applied.

Bounding box could help too
Maybe If you can upload a DWG.
