dgn (microstation) to SolidWorks

Hi

I have some models in dgn format that I need to import to SolidWorks.

In Microstation the model have several layers that devide the assembly into different sections.

The question is; Is there any way to import this dgn file into SW so that the layers become subassemblies?

When exporting to step from microstion and importing to solidworks all the parts from the model ends up in one large assembly, not divided in any way.

Other than that the models are perfect solid 3D models with the same colors that they have in microstation.

Using Microstaion 8 and SW 2010 sp4.

(It's a large assembly with thousands of parts, so I'm hoping I won't have to resection it in SW)

Any help will be higly appreciated

Thanks
