Download for MacParametric modeling on Mac, with print prep built in. Menus, Cmd-K, CLI, and MCP share one catalog.
Parametric history you can roll back. Assemblies, blueprints, and print prep built in. Generators include Screws and Gridfinity.
Preview the bed, split big parts with dowels or dovetails, and see thin walls and overhangs before you print.
Counterbored, countersunk and threaded holes in standard sizes, fits with clearance, and exact sizes in every sketch.
Assemblies of named parts that sit flush, with a dimensioned blueprint sheet for each part.
Generators for screws with nuts and washers, Gridfinity bins, filament tiles, and trail medallions from a GPX track.
Dimensioned drawings across several sheets, a sheet for each part, numbered against the parts list. In blueprint blue or white paper, and always up to date: change the model and every sheet follows.

Menus, Cmd-K, a CLI, and a built-in MCP server share one catalog of about 70 commands. Faces and edges keep stable names.

Yes. Menus, Cmd-K, the solid CLI, and a built-in MCP server all run the same catalog of about 70 commands. Agents can also query geometry by meaning.
Claude Code is the agent we have tested.
Import STL, OBJ, 3MF, USDZ, STEP, glTF/GLB, and IGES. Export those formats plus PNG. Native files use .solid.
Solid previews your printer bed, flags thin walls and overhangs, picks a support-aware orientation, and splits big parts into bed-sized pieces. Then export STL or 3MF.
