I have some issue with threejs. I have a hard object3d which contains sphere, cylinder, circles. These geometric shapes form a complex object. I add this object to scene and and next i add the same but smaller object to the scene. I can rotate first object, but when a small object goes beyond the borders of a large one, I need to clip it like overflow: hidden in html :-). I found library "three-csg-ts " but this library works only with geometry. I tryed use it, It's not correct for me. Because i need rotate this object before i put it on scene.

Maybe somebody can help me?
