Lesson 21 of 22
Generate a true 2D cutting profile with mounting holes, ventilation slots, and optional measured kerf compensation.

How this model works
This model stays entirely 2D: it has no extrusion and must use SVG or DXF, not STL. Capsule slots are distributed within a fixed border, so changing the slot count preserves the outside envelope. A positive offset of half the measured kerf expands the outer contour and shrinks the openings, creating centerline paths intended to compensate for material removed by the cut. Kerf defaults to zero. If you enable it here, do not apply compensation again in CAM. Verify units, contours, material, and your machine's import settings before cutting; the model does not set power or speed.

Make it your own
Export the zero-kerf profile and inspect its dimensions in your cutter software. After measuring a test cut, enter that kerf and confirm the outside toolpath grows by kerf while each hole toolpath shrinks by kerf. Do not double-compensate in CAM.
Change one parameter at a time and inspect the result. Use the workspace reset action to return to this lesson’s original model.
