Convert STP to DXF for 2D Drawings and CNC Profiles
Extract 2D drawing views or flat profiles from a 3D STP model — useful for laser cutting, CNC routing, or generating technical drawings from a solid CAD design.

Why Convert STP to DXF?
CNC routers, laser cutters, and many drafting workflows expect DXF, but your source design often exists as a 3D STP model. Converting bridges the two by extracting flat geometry from the solid.
This works best for models that are inherently flat or near-flat (sheet metal parts, panels, laser-cut profiles) — for fully 3D solids, the conversion extracts contours/silhouettes rather than a true multi-view engineering drawing.
Since DXF is 2D, the output loses the depth information in your original STP model by design — only outlines and flat profile geometry survive.
How to Convert STP to DXF

Frequently Asked Questions
Will this create a proper multi-view engineering drawing?
No — it extracts flat profile/contour geometry, not a full annotated multi-view drawing with dimensions. For that, you'd typically use your CAD software's dedicated drawing/layout tools.
What kind of STP models convert best?
Flat or near-flat parts — sheet metal, panels, laser-cut brackets — convert most predictably, since their geometry is already close to 2D.
Why did my conversion produce an unexpected outline?
For fully 3D solids, the converter extracts a silhouette or cross-section rather than every internal feature — complex solids may need a specific view or section defined in CAD first.
Are dimensions and annotations preserved?
No — STP doesn't carry drawing annotations, so the DXF output is pure geometry, ready for you to add dimensions in a CAD/drafting tool if needed.
Can I use the output directly for laser cutting?
Yes, for parts that are genuinely flat or profile-based, the resulting DXF is typically ready for laser cutting or CNC routing software.
