Octodraw

Octodraw is a Kotlin + libGDX desktop modeler for fast, direct 3D sketching. It focuses on edges, planar faces, tool-driven workflows, and precise snapping with an extensible plugin system.

Highlights

• Draw edges, create faces, and push/pull solids.
• Line workflows include chained Line and single-segment Construction Line.
• Surface-aligned rectangles, quads, and circles.
• Snap to grid, endpoints, midpoints, lines, faces, and guides.
• Objects (groups) with prototypes, instances, and edit mode.
• Linear dimensions and text entities.
• Scale supports axis-constrained squash/stretch when reference direction is aligned with X/Y/Z.
• Real-time lighting and shadow controls.
• Groovy dev console and plugin system.

Quick workflow

1. Draw a closed loop with Line/Rectangle/Quad/Circle to create a face.
2. Use Push/Pull to extrude.
3. Add guides (G/T) and snap for precision.
4. Group geometry into Objects (Ctrl+G) and place instances.
5. Paint faces, add dimensions, and tune lighting.
