Exploded view in Multi Body Part and Weldments

Multi body parts are great and weldments are a lot easier then at assembly level is my opinion.

But, is it possible to create an exploded view within a multi body part ?

What's your opinion about weldments in a part vs in an assembly.

Is it possible to use tangent propagation in an assembly weld ?

Greetings !
