Drawing → part

From a drawing or an image to a 3D part at real scale

Have the drawing of a plate, a panel faceplate or a silhouette? reverse3d extracts the contours (with their holes), vectorizes them and extrudes them to the thickness you choose, at the real scale you give it.

The problem

  • Redrawing a plan in CAD just to extrude it is wasted time.
  • Online converters lose the holes or the scale.

What you get

  • Vector contours with holes (SVG and JSON).
  • Real scale from one known dimension or mm per pixel.
  • Extruded solid (STL) and render.

How to do it with your AI agent

  1. 01

    Give it the drawing

    An image on a light background or a PNG with transparency.

    “Extract the contours of bracket.png.”

  2. 02

    Set the scale

    One known dimension is enough.

    “This drawing bracket.png is 120 mm wide; make me the part 4 mm thick.”

From the terminal

reverse3d run plan_to_part drawing.png output/ --thickness 4 --units-per-pixel 0.5

Frequently asked questions

Does it work for laser cutting or CNC?

Yes: besides the STL you get the contours as SVG.

Does it keep inner holes?

Yes, the contours include the holes.
