Modeling Volkswagen Sedric - Power Surfacing | SOLIDWORKS 

Blender

You can save as obj and open it in blender with the quad mesh. Choose the right save option. You have 2 types of obj. One with the same quad size and the other one with subdivided obj

For rendering, you can use rhino software to save it as obj. It's good keeping the same quad selection workflow.

@@npowersoftware6638 Thanks you but i have some concerns: 1. after design in Solidworks, which type of file we will save as to keep quadmesh, because Solidworks does not have Obj file type? 2. i tried to save as STEP but after import to Blender, it will be convert to triangle mesh, it's quite hard to mapping UV or rendering? Please help! Same question if we use Power Surface add-in?
