I have updated this plugin to V1.0.3. The changes allow a surfaces to be clipped by a closed shape in the X,Y plane.
While this could have been done in the previous version (by creating a flat surface at Z=0, then "Adding" it to the selected Surface, the new options are simpler to work with, if all you want to do is to clip a given Surface to some arbitrary shape in the X,Y plane. The clipping shape can be a closed Polyline, a PolyRectangle or a Circle.
