Concentric Mates
We know that each unconstrained body in space has six degrees of freedom (DOF): three translations and three rotations about X, Y and Z axes. Each mate removes a certain number of DOFs from the system. The table below shows some of the mates in…
Working with downloaded or imported models can create a situation where multiple pairs of holes cannot be mated concentric although there is no problem fitting manufactured components. SOLIDWORKS 2018 misaligned concentric mates option can account for this small difference in hole distances. When the option…
Working with assemblies we sometimes have holes that are slightly misaligned, especially when working with imported parts from a supplier. Even though they are still within spec and will work for the intended use, we get the Over Defined ketchup and mustard in our feature…
Starting in SOLIDWORKS 2014, you have the ability to lock rotation of concentric mates. This can help avoid additional mates required if you didn’t want the components to rotate. Review Chris’ blog post for a quick tutorial of this functionality. How to quickly tell if…
