Smart usage of Kerf on narrow geometries

Hi,
I am trying to find a fix for my issue since some days without success. Also tried other software but it seems to be a general issue. Maybe there is a setting or a workaround and I can’t find it.

The problem:

I want to create a living hinge made of line from a 3D model made in Fusion 360. Please note that for my workflow it is important to use data exported from 3D! Generating a DXF from a sketch is not an option!

The issue is that if you model a living hinge you need to cut out each gap from the main body to be able to see the hinge the same as it will appear later on the final product. I usually do this in a Sketch by adding lines, extrude them, thicken them and then substract them from the main body. For the thickening I use the same value as the laser kerf (0,11mm).
If I now export the data based on the 3D the gaps of 0,11mm are of course not lines but rectangles with a width of 0,11mm and 25mm length. Means the software does identify them as such and runs the path around the rectangle which is taking double the time as it would just cut a line.
My idea was to create cutouts with the laser kerf thickness and the set the same kerf in the software (-0,11mm) hoping it would be smart enough understanding that the cut area after one travel would be already the same as the overall area that need to be cut, and therefore optimizing the required travel path.

No software seems to be able to do this though, or I am just not able to finding it. Can you tell me if you were already facing similar issues and found a way to fix it. Again, exporting the geometry from a sketch as lines is not an option for me.

Looking forward to any advice!

Regards Christian

I doubt that’s possible. You might try to use the “remove overlapping lines” optimization feature in laser window. But I don’t know if LB will use the overlap detection before or after the actual path is calculated. I guess it uses the information before final path calculation.
