Tecnomatix Plant Simulation supports to import JT files and VRML files.
The JT file format is an ISO standard for 3D data exchange. But I don't know if SolidWorks can write this format. In any way it should support to write VRML files.
If information is lost in the VRML export and you have access to our product Teamcenter Visualization you can use this application to convert other standard formats like IGES, STEP and STL to the JT format.
