So I found the bowl project video he mentioned which was to show the new features in Kiri:Moto CAM for milling double sided parts. Here Kiri:Moto is integrated as a tab in OnShape but the only thing that really does is make it super easy to import the part. Realistically this isn’t very difficult anyways if you use a browser to download your 3D model because I learned you can use the browser icon created after downloading to drag/n/drop the model into the Kiri:Moto tab of your browser. Anyways, this 6 minute video shows the techniques for getting your registration marks in your “stock” and in your spoil board then setting the different toolpaths( rough, outline, contour, drill, and tabs ).
