Import a model

Bring in STL, 3MF, OBJ, GLB, STEP, SVG, or OpenSCAD .scad/.csg.

Imported meshes and STEP solids join your document like any other object. OwlCAD detects the source units on import so the part arrives at the right scale. An SVG becomes editable extrudes. OpenSCAD works two ways: import a .scad script directly — OwlCAD interprets it (variables, modules, functions, for/if loops) into an editable tree of primitives and booleans — or, for scripts using features OwlCAD does not evaluate, export a .csg (openscad -o out.csg in.scad) and import that instead. A plain STL/3MF from OpenSCAD imports as a mesh. The Import submenu has two more OpenSCAD entries: OpenSCAD code… takes source pasted straight in (handy for a snippet you copied, with no file to save first), and OpenSCAD folder… loads a multi-file project, resolving its use/include against the sibling files.

1. File → Import → Model file…
2. Pick a file; units are detected and converted to mm.
3. The geometry drops onto the plate ready to edit.
