I'm importing .stp files so I can make a print to check the parts (solidworks 2014). I have been successful with simple flat parts with parallel and perpendicular sides. I'm having problems with curved parts. For starters XYZ zero on these parts are are way out. when you press the fit key all you see is two specs on opposite sides of the screen. I'm familiar with the move/copy body command but not having any luck due to the surfaces not being flat. My first question would be how to get part zero closer to the top/front/right planes? Next question would be how to get dimensions for the surface that looks flat but actually has a very slight curvature.
I have been trying to figure out what direction to go by reading and doing solid professor, Nothing I have found seems to help with the problems I'm having.
