3D Profile Cut Ordering

Hi,

I've been using CB for a while now and have had no issues with 2.5D milling. I've started importing 3D STL files from Sketchup (results in very 'messy' 3D surface - is there any way to 'clean' this up?) and creating simple 3D profiles.

I tried creating a 3D profile on a model which required both inside pocketing and outside profiling. My issue is that when running the gcode on the mill, CB decided to profile the outside of the model first, and because there are no holding tabs, the part is no longer being held/clamped in place when the inside pocketing needs to be done.

Is there any way to force CB to 3D profile the inside regions first, then the outside regions? Would using two separate MOP's fix this?

Thanks,
Tim
