.cf TOML files, validate it, preview it visually, and compile it deterministically to DXF. ## Core Features & Use Cases - CAD as code authoring: Declare lines, polylines, circles, arcs, text, dimensions, hatches, arrays, mirrors, and 3D solids with CSG booleans in .cf TOML layers orchestrated by project.toml. - Validation and visual verification: Run cadspec check --json for machine-readable validation and cadspec preview to render PNG/SVG previews with entity highlight markers so edits can be confirmed visually. - Live preview and DXF pipeline: Use cadspec serve for a browser live preview that refreshes on save, cadspec build to compile DXF, and cadspec import to convert existing DXF files into .cf layers. - Use Case: Ask the agent to scaffold a floor plan project, draw walls and dimension annotations in .cf files, preview the render to verify placement, then build the final DXF for delivery. ## Quick Start Ask the agent to create a new cadspec project, start the live preview server, and add a dimensioned rectangle to the main layer.High-intent search queries and answers about installing and using this skill.
Run cadspec new to scaffold a project, then declare geometry in .cf TOML files using primitives like line, polyline, circle, text, dim, and hatch. Compile the layers to DXF with cadspec build or preview them with cadspec preview.
Run cadspec serve to start a live preview server on port 4377 that daemonizes by default and refreshes the browser about 80ms after each save. Stop it with cadspec serve --stop, or use cadspec preview to render a static PNG or SVG.
Yes, cadspec renders a real extruded 3D view via cadspec preview --3d or the viewer's 3D button. Primitives accept extrude and elevation attributes, and [[solid]] blocks with [[boolean]] operations support difference, union, and intersection.
Yes, cadspec import <file.dxf> converts an existing DXF drawing into .cf TOML layers, optionally targeting a named layer with --layer. The resulting files can then be edited, validated, and rebuilt like any cadspec project.
cadspec check only validates layers, entity counts, and constraints without writing output; build --check behaves the same way. To generate the DXF artifact, run cadspec build, optionally with --layer or --output flags.
cadspec supports extrusion and CSG booleans on box and cylinder solids, but not a B-rep feature tree or interactive sketch-on-a-face workflows. Cutting operations require positioning the tool solid by coordinates rather than selecting faces interactively.
