problem in ' Assembly from polyline' , any one can help me ??

[Anonymous]

after i create my subassembly from polyline , I select it to add it to assembly but the option ' Add to Assembly ' isn't active in Ribbon Panel , Why ??

What if you click on the subassembly and then right-click. Is the option in the menu there?

No , I try this method but the option not found too .

Perhaps it's already added to an assembly without you being aware of it (it happens). Copy the subassembly using the AutoCAD copy command and then try adding the copy to an assembly.

The problem solved finally ,

Thanks for all .
