How can the assembly in Solidworks be edited after being imported into Comsol by Livelink?

Hi all,

I imported an assembly from Solidworks to Comsol using Livelink. I have a few questions as follows:

1. Where can I see and change the x, y, z position of the imported model? I want to add another block around the imported model, but I don't know the exact position of the imported model.
2. How can I separate 2 parts to do a parametric sweep? In the assembly there are two parts which move relative to each other. After importing, the assembly is a whole part. I want to do a parametric sweep between the two parts in position. First, I can't move them separately. Second, I can't edit the position. How can I separate all parts to edit and do a parametric sweep?

Could anyone help me with these? Thanks a lot!

Cheers,
Ruijun
