Engineering drawing

Provenance: maintained in earthtojake/text-to-cad. Use the installed local skill files as the runtime source of truth.

An engineering drawing is a DOCUMENT derived from a part. cadgen.eng_drawing projects views from the part's geometry, places dimensions between points ON that geometry, finds centre marks on it, and lays the result out on an ISO sheet with a frame and a title block. Change the model, rerun the drawing script, and the views, hidden lines and measured values move with it. Nothing on the sheet is drawn by hand, and nothing on it is a number you typed unless you chose to override a value.

The output is one PDF. That is what a shop receives and what every operating system opens. No DXF is written, nothing is paired or linked, and there is no CLI: the script is the interface. $dxf makes cut layouts and flat patterns, which are toolpaths, not documents; the two are different jobs.

Setup

Run cadgen through the cadgen command its installation writes, so this skill's commands share one installation, and its engine server, with the CAD app's:

• cadgen below means cadgen +0.8.4 (~/.local/bin/cadgen +0.8.4 where ~/.local/bin is not on your PATH)
• python below means cadgen +0.8.4 run

For first-time setup or an update, a missing cadgen command, a release it says is not installed, an engine that is not running, or an installation or kernel load error, read Setup and troubleshooting.
