I just started using SolidWorks again after a year or so hiatus. I remember finding an answer for this but it was also debated. Fully defining a cylindrical part. Some people say not to, the less mates the better. Some say to fully define, less for solidworks to solve.
Which is the answer?
Examples: Nut that is welding on a hole. Shafts where you dont need motion in your assembly. Etc.
