I would like to know the quickest way to add fasteners, such as washers and screws, into an assembly and mate them to their associated holes.  These are fasteners I have created myself, and not in any SolidWorks toolbox.  The holes and parts that I am mating them to are not part of a pattern or something I can mirror.  I use to use Solid Edge, and it had a function called Capture Fit that would allow you to assign a concentric constraint to the inside diameter of a washer (for example), so that as soon as you brought that washer into your assembly it would automatically ask you what part you wanted to mate that concentric relationship to.  You could also assign a flush/mate constraint to the surface of the washer, and it would also ask for that mating surface when you brought the part in.  Literally two clicks after you inserted the component into an assembly it would be fully constrained in position.  I'm looking for something simular in SolidWorks.  Does anything exist?
