The software uses a pinball (imaginary sphere) to search for joints and define the participating structural members. The software creates joints at the intersection of this structural member and any other structural members whose sketches lie within the pinball. The software also creates joints at the free ends of structural members. The software ignores structural members that are parallel. The software calculates joints at the endpoints of all of the selected structural members.
