2D Section Cut from STEP

I have a clean STEP model and I need a precise 2-dimensional section cut that captures only the external profile. The final drawing must be delivered as a DWG that opens perfectly in AutoCAD without extra cleanup.

What I’m after
• Slice the STEP at the plane I indicate (I will pass a screenshot with coordinates).
• Export just the outer contour—no internal features, hidden lines, or construction geometry.
• Keep true scale and origin so it overlays correctly with my existing DWG layers.
• Line weights and layer names can stay simple; I can tweak cosmetics later.

Acceptance
I’ll load the DWG in AutoCAD 2024 and check that the profile traces the STEP model within ±0.1 mm, the file units remain millimetres, and the drawing is free of stray entities.

If you have experience converting STEP to DWG and can turn this around quickly, let’s get started.
