TYPE: SOP
TITLE: Extrude SOP

Extrude can be used for extruding and beveling geometry, cusping
beveled edges to get sharp edges, or making primitives thinner or
thicker.

Parameters:

    Source Group	 - The primitives to extrude.
    X-Section Group      - The primitives to use as the cross section.

Values
    Point Fusion         - Consolidates points of polygons that would 
                           otherwise overlap.     		 /doFuse
	All points       - Guarantees no overlapping points.
	Minimal          - Provides more uniform control
			   with overlapping only in extreme cases.
	Individual Faces - Implemented only for backward compatibility.
    Front Face           - Type of geometry to create for front face.
    Back Face            - Type of geometry to create for back face.
    Side Mesh            - Type of geometry to create for sides with 
                           polygonal cross-sections.
    Initialize Extrusion - Attempts to fit the cross section to the source.
    Thickness Offset     - Controls the tangential offset of the 
                           cross section profile.             /thickxlate
    Thickness Scale      - Controls the x scale of the cross section
                           profile.                           /thickscale
    Depth Offset         - Moves the entire extrusion forward or
                           backward along the extrusion.      /depthxlate
    Depth Scale          - Controls the y scale of the cross section
                           profile.                           /depthscale
    Vertex               - Translates the cross section such that the   
                           vertex specified is at the cross section origin.
                                                              /vertex
    Cusp Sides           - Whether sides are to be smooth-shaded or faceted.
    Side Cusp Angle      - Threshold angle for edge faceting. /cuspangle
    Consolidate Faces    - Consolidates the points of the face to the
                           points of the sides                /shareFaces
    Remove Shared Sides  - Prevents the creation of duplicate sides
                                                              /removeSharedSides

Groups
    Create Output Groups - Generates 3 groups.  One for front, back and sides.
    Front Group          - Name of the front group.
    Back Group           - Name of the back group.
    Side Group           - Name of the side group.
