mtShellGen extrudes polygon faces and creates hull and cap geometry.

This can be used to create 3D shells from polygon faces.

mtShellGen is using bevel options on a source Cube to create this geometry.

Object tab

Selection Map

You can use a vertex map or selection tags to define which polygons are extruded.

Drag the tag from the Object Manager into the Selection Map link field.

The Plane on the left has a polygon selection tag, which is displayed in the viewport. An identical Plane is on the right, as a child of a mtShellGen. The selection tag is driving the polygon extrusion.
