Negative Extrusions

Creates a negative extrusion by positioning PAVE elements to form a Loop (LOOP) and then extruding them. A negative extrusion represents a negative volume, that is, a hole.

A negative extrusion is owned by the panel through which the hole is positioned.

The example displays a negative extrusion through a floor plate, a column passes through the negative extrusion.

Vertices V1-V4 define the negative extrusion; the vertex numbering is independent of the panel vertices.

The outer edge of the negative extrusion (V1-V2) extends beyond the outer edge of the panel to make sure that the hole penetrates through the panel edge. Similarly, it may be necessary to define the thickness of the negative extrusion to exceed the thickness of the panel to make sure that the hole penetrates completely through the panel.
