At the request of some of our simulation customers, we have added the PATH entity to the 3Di database. This is useful for simulators that have specialized routines for computing the electrical properties of paths.

A path is a GEOM. It is associated with an Extrusion (which determines its Z thickness) It has a layer associated with it and because it is almost always a conductor, it will have a NET if the source was a PCB database.

The number following the path statement indicates the number of vertices.

Each line following the path defines an X,Y vertex coordinate pair and associated width at that vertex.

Notice that there is no end cap description for the PATH. For most purposes one should assume when rendering the PATH that its end caps are round and that at any bends it has an outer radius equal to 1/2 the width.
