How much experience do you have with complex surface modeling in Solidworks? The process is actually very similar to Rhino in so much as creating surfaces from curves, surfaces or a combination of surfaces and curves. The only real differences are that you use different tools in the same situations (e.g. Solidworks’ loft tool is very powerful while the swept surfaces kind of suck. Rhino is the opposite.) and that Rhino lacks the powerful history editing capabilities of a parametric modeler. Find a couple quick tutorials on creating NURBS curves in Rhino (which is a thousand times simpler than complex splines and 3d sketches in solidworks), and you’ll be off and running.
