Hammer CAD

Hammer CAD is a simple 3D CAD program for Linux. It makes models for 3D printing. The workflow comes from the Hammer level editor: four viewports, a grid with snap, and solids that you draw as boxes. Some features come from Fusion 360: sketches on faces, extrude, revolve, fillets, and face tools.

This program is vibe coded: an AI assistant wrote almost all of the code. It uses KDE Frameworks, but it is not affiliated with KDE, Valve, or Autodesk.

Features:

• Boxes, cylinders, cones, spheres, and more primitives with grid snap
• Sketches with lines, arcs, curves, rectangles, circles, slots, and holes
• Extrude, revolve, booleans, fillets, chamfers, press/pull, shell, and smooth
• Holes, text, measure, and placement tools for 3D printing
• STL and 3MF import and export, with watertight meshes
