2D Pocketing with islands

This is a continual post of the 2D Contouring.

So, what if my pocket contains islands? No problem, just select the island's edges at the same time as you define the pocketing curve and they will be protected.

I added a center axle on the extender model as an example.

1. Workpiece and cutter is already defined, so I go directly to 2D Icon-Pocketing.
2. I select the pocket edge and the axle (island) edge and press enter when ready (or right mouse click, which is standard in Rhino).
3. I use the same setting as before, just go for it.
4. Now in the simulator, I see my center axle preserved.
