I am using Desktop and can't seem to get the Gap Under Model in material set up to work properly. I also tried adjusting the model base height and can't get that to work right either.

So I have a block of wood 2.25 high, 3 wide and 7 long. I am making a 2.125 diameter ball directly in the middle of the block of wood. I am using the 2 sided feature and the Dome 90 from clipart. Right now every time I create a toolpath I basically cuts through the material so nothing is holding the ball after I machine it.

I would like to place a 1/32 gap under the model on each side so after I cut I will end up with 1/16 inch of material all the way around (to hold the ball in place) after machining.

How do I do this? What am I doing wrong? It appears to work in Aspire but I need to get it to work in Desktop.

Any insight would be greatly appreciated.
