Voxel Forge Studio — 2D Draw to 3D

Draw a 2D outline, turn it into a voxel-style 3D object, and export the selected object for further work.

What this tool does

Voxel Forge Studio combines a 2D drawing canvas with a Three.js 3D preview. Create separate objects with line or freehand paths, choose perimeter or area voxelization, set depth, add holes, tune voxel resolution and spacing, and export the selected object as STL, GLB, or OBJ.

Who this is for

• Makers and designers turning simple sketches into printable 3D drafts
• Students learning how 2D paths can become voxel-style geometry
• Developers testing a lightweight browser workflow for geometry export

How to use this tool

1. Create an object, choose its color, and set its depth in millimeters.
2. Draw with Line or Freehand, optionally use Snap to Grid, and use Add Hole for a diameter and length.
3. Switch to Preview 3D, choose resolution from 5–100, voxel spacing, and Cube or Sphere shape.
4. Regenerate the 3D preview, then choose STL Binary, STL ASCII, GLB, or OBJ.
5. Click Export Selected Object to download the current object.

Inputs

Inputs include drawn points, object color, perimeter or area fill, depth, hole dimensions, grid scale, background-image opacity, 3D resolution, voxel spacing, voxel shape, and export format. An imported image is a raster tracing background; it is not automatically converted into geometry.

Outputs

The page shows the active 2D drawing and a generated 3D voxel preview. Export creates one selected object as STL Binary, STL ASCII, GLB, or OBJ. The controls do not provide an Export All action or a project save/load format.

Example use cases

• Draft a simple sign, plate, ornament, or enclosure concept
• Add a circular opening to a sketch and review its voxelized form
• Export a quick model draft for inspection in another 3D application
