I need help with a file. On my 4th version

I have imported a stl file and assigned the toolpaths. The simulation shows the stl image cutting well but it also shows the project perimeter being cut fully out.

I would like to have a 1/4 inch perimeter around the project and can’t figure out how to do that.

Any help or guidance would be greatly appreciated.

right-click on the 3D model:

trace it:

OK

Select that and the border:

Model as an 0.25" flat thickness:

Apply

Will, Many thanks, You took a few minutes to fix a week of frustration

An alternate approach would be to set the model to “Equal”, then draw in the flat area before hand.
