Two examples of virtual clips (cableconstraint.sldprt and virtualclipsingleconstraint.sldprt) are located in the Design Library, in the <install_dir>\data\design library\routing\electrical folder.
One configuration of cableconstraint.sldprt is shown below. One of the edges of the extrude is used in a mate reference definition, to facilitate positioning the part in an assembly. Axis of Rotation and Clip Axis can be used to rotate or align the virtual clip. The virtual clip contains overlapping configurations and filter data, so it automatically resizes to provide different offset distances when the cable diameter changes.
