Scriptable CAD with Lua. Write parametric 2D and 3D models in Lua and export them to 3MF, STL, OBJ, PLY, OFF, AMF, or SCAD, or render them straight to a PNG. LuaCAD embeds Lua 5.4 in a Rust engine that evaluates CSG operations directly (via Manifold ) or generates OpenSCAD code for external rendering. Why Lua? Similar syntax as the OpenSCAD language, but better: More powerful More consistent Faster Easily embeddable Operator overloading for natural CSG syntax ( a + b , a - b , a * b ) Already used in other CAD software like LibreCAD and Autodesk Netfabb Example LuaCAD: my_cube = cube { size = { 1, 2, 3 } } function my_sphere(radius) return sphere({ r = radius }):translate(5, 0, 0) end model = my_cube + my_sphere(2) render(model) Equivalent OpenSCAD: module my_cube() { cube(size=[1,2,3]); } module my_sphere(radius) { translate([5,0,0]) sphere(r = radius); } union() { my_cube(); my_sphere(2); } Getting Started cargo install luacad # CLI for running and converting LuaCAD scripts cargo install luacad-studio #…
