Adding material for removal on imported solid

New to BobCAD… previously ran w/ FC

Running v32…

Importing a stp… (not sure if should import as ‘original’ or ‘make one solid’ & not sure if it should be defined as ‘wireframe’ or ‘solid’)

I’m attempting to rough and finish mill the perimeter of flame cut blank. I am under the impression that being as the model is finish size, I am not generating a roughing tool path ((finish cut runs incorrectly through the middle of part as well) assuming that’s a geometry selection/tool path mistake).

Is there a function to add material to be removed?

I appreciate any input.
