InsoleCAD is located behind the "Insoles" button.

This allows you to model the top of the inserts using 2D and 3D scans and pass them on to a 3D printer or milling machine to print/mill a finished insert. You can also define the share hardness for the 3D under the "Cubify" button.

 

A complete explanation of the InsoleCAD module can be found in the GP InsoleCAD manual.
