Cubic Trefoil Knot: This model demonstrates a different technique for creating a weldment without using a 3D sketch or a collection of 2D sketches. This multi-body part is called a Cubic Trefoil Knot. It is a 3D-golygon (knotted golygon). Instead of using standard weldment structural members, the building blocks are created then patterned.
Features: Move/Copy Body, Constraint
