Hi, I was given an STL file of a part and would like to sketch a similar part; improve it, add draft, make it injection "friendly" etc. Problem(s) (I am sure there are more that everyone else here knows about!): The part is not near the origin, and I cannot sketch off any surface, I.E. create a plane on or near the part, and I need to measure the part to get it close, but because it has no features I cannot measure... What is the best way to go about getting this (ghostly) part into SW 2005 SP3.1 Certainly some data is there, SW & OpenGL draws it! I have never had this particular problem and just cannot figure this one out! Thank you, Aron
