This part is configured as an Ipart Factory. When you Place the part in an Assembly, the system asks the user to introduce 3 parameters (Internal Diameter, External Diameter and Length), which determine the part’s dimensions. This way you can place and use parts with an infinite number of size combinations, without drawing a single line.
