## Description

Make an engineering drawing of a part as a PDF - orthographic views with hidden lines and centre marks, real dimensions, hole callouts, notes and a title block on ISO sheets, all projected from the part's geometry so the drawing follows the model. Use when the user asks for a drawing, a dimensioned sheet, shop or manufacturing drawings, a print, or "2D views of this part".

# Engineering drawing

Provenance: maintained in [earthtojake/text-to-cad](https://github.com/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](references/setup.md).
