Connect Segments: When checked, the tool
will create polygons "joining" each level or segment in the extrusion, creating
a traditional ducted solid.
Create Endcap: When checked, the tool will
create an "endcap" polygon at the far extent of the extrusion, identical to the
polygons being extruded.
Create Layers: When checked, the tool will
create "layer" polygons at each segment in the extrusion, identical to the
polygons(s) being extruded. Normally, this option would be used with Connect Segments off,
to create clones of the selected polygons.
Extrude Last: When checked, with Connect
Segments on, the tool will extrude the last segment of each selected polygon.
Segments: Controls the number of segments,
or "layers" in the extrusion.

Offsets X, Y, Z: Control how far the
extrusion is offset along the axes. Use the ControlChannels to make the offsets non-linear
along each axis.

Scale X, Y, Z: Control the
scaling of the extrusion polygons along each axis. Use the ControlChannels to make the
scale factors non-linear along each axis.
OK: Creates the extrusion polygons and
closes the tool.
Cancel: Closes the tool without creating
the extrusion polygons.
The Extrude tool also includes a standard Origin
Tab, allowing you to set the origin along which the tool extrudes and scales polygons.
