Hi all Aspire users, I've been having issues with 3D finishing toolpaths being really inefficient when cutting out 3D components that have flat surfaces equal to the Z height of the material (flat on top).

I'm slicing a large 3D component into slices so I can cut them out and then assemble them afterwards.

Several of these sliced 3D components have FLAT parts that signifies the top of the work piece being cut out.

For whatever reason, when I generate a 3D finishing toolpath, Aspire creates toolpaths that run the cutter over the FLAT areas unnecessarily... and this ends up doubling or even tripling the machine time.

I realize it is hard to visualize this problem just by explaining so I've made this video to demonstrate my issue:



I'm wondering if I'm missing a step when creating the flat-area vector boundaries?

Here is the original Vectric tutorial I followed:

Many thanks for any insight you can provide! Cheers
