Core thickness profile in CAD software

Demonstrating one way to create core thickness profile data and generate g-code to cut ski or snowboard cores on a CNC router. A customer that uses an old version of BobCAD software asked us to show a workflow to taper cores on their CNC. While it shows the workflow on an old version of BobCAD, even if viewers use a different package It should give them an idea how to do similar steps in their own CAD package.
