After creating a multibodies from one body we can can create an assembly out of these new parts that were created by using a split command.
We go to insert features create assembly. Than a property manager appears on our left side asking us to select two things.
First thing is a split feature already created.
The second thing is we brows and we give name to an assembly that we are creating. The assembly is saved in the same folder as newly created parts after the split.
After clicking OK the assembly appears and we rebuild an assembly.
The assembly mode is now opened and we can see our parts in the design manager tree.
When we open our part we can see how it looks.
