Enable outer object boundary exclusion.

-Is there a way to enable temporary object exclusion for objects during modelling?

-Is there a way to enable animation exclusion so that any shake key interpolations between key frames are stopped from colliding with another object or other, mutually?

can you elaborate on first part !

you can hide verts !

you could hide part with Alt- B box !

-All shapes or solid have a a surface or an outer surface, respectively. Is there a way that I can axially “slide things around”
such that when the beginning of one begins to encounter the extremity of another (object), that the moving object
will stop sliding and not arbitrarily pass through as normal [in construction mode]?

there is some obstacles collision thing in BGE
but have not work with this effect !

may be someone else can help
