While editing component from assembly my assembly rotate and now in drafting
it is going taper in one axis please find attached images .
I don't see the assembly and its structure but I can say you could try to mate the main component of the assembly to Top, Front and Right planes rather then the default "fix" (f), so it keeps the correct orientation on the views.
this is the best solution for it.
Exactly, whats your question?
You want to know why the assembly is not in the correct angle or you want to find out how to rotate it back?
If you take a screen shot of your model, it would be nice to include the Design Tree also. Those little icons next to the part and assembly names can actually help identify your problems.
Also, I am not sure what your question is and what you are trying to do. I am going to assume that your assembly is not mated correctly to the 3 main planes.
See if Why can't I move the first component I inserted in my Assembly? will help you.
