Trace3D Pro

A browser-based drafting workspace for turning 2D paths into configurable 3D extrusions.

What this tool does

Trace3D Pro lets you draw or trace 2D vector paths, turn closed paths into solid areas or hollow walls, and inspect the resulting geometry in a live 3D preview. It combines a 2D drafting canvas, vector layer controls, and browser-side mesh export in one workspace.

Who this is for

How to use this tool

  1. Accept the welcome screen, then choose Line, Free, Rectangle, Circle, or Curve to draw, or upload an image under Trace Background as a visual guide.
  2. Use Select, Pan, zoom, grid snapping, and vertex snapping to refine the 2D draft. Close a path with Close/Finish Path or Enter when it should form an area.
  3. Select a vector layer and choose Solid Area or Hollow Wall. Set its extrusion depth, and set wall thickness for hollow geometry.
  4. Review the result in the 3D Preview, including layers, triangles, and X/Y/Z dimensions.
  5. Export the current model as GLB, STL, or OBJ using the buttons in the top bar.

Inputs

Draw paths with the line, freehand, rectangle, circle, and curve tools, or upload an image/* background reference. Optional grid size, grid snapping, and vertex snapping help position points. Each layer can use a solid or hollow mode, an extrusion depth in millimetres, and—when hollow—a wall thickness between 0.5 and 20 mm.

Outputs

The app renders the drafted paths in 2D and generates an interactive 3D preview with layer count, triangle count, and dimensions. The export controls download the geometry as GLB, STL, or OBJ files for inspection or use in a compatible 3D workflow.

Frequently asked questions

Can I trace an image in the workspace?

Yes. Upload an image under Trace Background; it is displayed as a guide behind the 2D drafting canvas while you draw paths.

What is the difference between solid and hollow modes?

Solid Area creates a filled extrusion from a closed path. Hollow Wall creates an extruded perimeter and exposes a wall-thickness control for open or enclosed path outlines.

Where does processing happen?

The page reads the reference image and builds the draft and preview in the browser. Exported files are generated by the page when you choose GLB, STL, or OBJ.
