In previous posts, I drew the basic 2D curved shape for the BARN Workbench vise chop using CAD software. Because I was still at the beginning stage of the project, I also designed and built a jig that holds the blank stock during machining on a CNC. Now that the basics are out of the way, it’s time for the fun part: Turning a simple 2D shape into a 3D vise chop.

Here’s the 2D shape we started with.

That purple line, with the red guide lines in the middle, is the basic shape of the vise chop and the basis of all the 3D work to follow.

Now, let’s take that 2D shape and use it to create a 3D object. One way to do this is a process that’s almost universal amongst 3D CAD programs. We’ll use the extrude function to turn the 2D lines into a 3D form.
