Draw 2D shapes, extrude them into 3D blocks, stack them up, and export your creation — all in one browser tab.
What this tool does
Voxel Forge Studio lets you build 3D models by drawing 2D shapes on a canvas and extruding them into blocks. Move, rotate, and scale objects using intuitive controls. Export your final model as OBJ or GLB.
Who this is for
Beginners who want a simple introduction to 3D modelling
Makers creating blocky 3D prints
Game designers sketching voxel assets
Students building 3D geometry from 2D cross-sections
How to use this tool
Draw a 2D shape on the canvas
Click 'Extrude' to turn it into a 3D block
Move and stack blocks to build your model
Export as OBJ or GLB when done
Inputs
2D canvas drawing — Shape drawn on the flat canvas
Extrude amount — How far the shape is pushed into 3D
Transform controls — Move, rotate, scale in 3D
Outputs
OBJ — Import into Blender or slice for 3D printing
GLB — Use in Unity, web, or AR viewers
Example use cases
Blocky robot — Build a voxel robot character from simple box extrusions
Architecture volume — Sketch a building massing model quickly
Game asset — Create a chunky game prop for a Minecraft-style game
Math solid — Build a prism or pyramid from its 2D cross-section
▶ Is this different from the 2D to 3D Voxel Modeler?
Yes — Voxel Forge has more object management features and supports multiple extruded objects in one scene.
▶ Can I load an existing model?
Not currently — you build from scratch using 2D extrusions.
▶ Can I print the output?
Yes — export OBJ and import into your slicer. Add supports where needed.
▶ How many objects can I have?
Tens to hundreds — limited by your browser memory.
