Start from SolidVents
In SolidVents, choose Export → Wrap: the pattern opens in Wrap.
- To edit it, click the thumbnail and send it again. Only the pattern is swapped.
Click the face, flatten it
Import your STEP, click the face and press Flatten.
- Planes, cylinders and cones: 0% distortion.
- Domes and freeform faces: minimum distortion, shown as a heat map.
Place the pattern
Scale, Rotate and Move it on the flat. The 3D view follows.
- Shapes crossing the edge become notches.
Raised, recessed or cut through
Pick Raised, Recessed or Cut and see it live in 3D.
- Height, draft angle and fillets are adjustable.
Export STEP
Export → STP, in your part’s own coordinates.
- Surface or Solid; Split STP for dense patterns.
- For the flattened outline, use Import outline into SolidVents below the flat view.
Questions
Which CAD programs can open the STEP?
Any CAD that imports STEP (.stp). The pattern lands where it was on your part.
Is my STEP file uploaded?
No. Everything runs in your browser.
Which surfaces can Wrap flatten?
Planes, cylinders and cones unroll exactly; spheres and freeform faces with minimum distortion. Tangent faces can be flattened together.
Which pattern files does Wrap accept?
SVG and DXF exported from SolidVents.
