I am new to soildworks and had a question. I am designing a table with a glass on it. I have created all the parts and assembled everything, however i wish to make it so that the cup can only slide across the tables surface. I have tried mating the cup to the tables surface, however when i move the cup around it can go over the tables edge. I am wondering if there is a way to make it so that it only moves across the top of the table.
