kernelCAD — engineering drawings

export({ target: 'model', format: 'svg-drawing' }) renders a .kcad.ts model as a standard third-angle engineering-drawing sheet in SVG. It works on single bodies and on assemblies (assembly.model() / solvedModel(...)) — assembly parts are projected together in world frame, so one part occluding another renders correctly as hidden lines.

What the sheet contains

• Views: front, top (above front), left (left of front) — third-angle arrangement with shared-axis alignment — plus an isometric pictorial in the upper-right cell. One drawing scale for all views, snapped to the standard series (…, 2:1, 1:1, 1:2, 1:5, …) and stamped in the title block.
• Line styling per drafting convention: visible edges solid full-weight; hidden edges dashed half-weight; tangent edges (fillet boundaries, smooth face transitions) thin solid. The isometric view omits hidden lines.
• Dimensions: by default the overall bounding box — width (under the front view), height (right of the front view), depth (left of the top view), with extension lines and arrowheads. Values are model millimetres. Author your own with annotations (below) to dimension actual features instead.
• Title block: model name, scale, units (mm), date, and the third-angle projection symbol.
• Coincident projected segments (e.g. a bore's front and back rim landing on the same arc) are deduplicated visible-first — nothing renders twice or dashed underneath a solid line.

Quickstart

MCP:

{ "tool": "export", "input": { "target": "model", "file": "bracket.kcad.ts", "format": "svg-drawing", "output_path": "out/bracket-drawing.svg" } }

CLI:

kernelcad export svg-drawing bracket.kcad.ts -o out/bracket-drawing.svg

Options

Pass via options (MCP) — all optional:

• sheet: 'a4' (default, 297×210 landscape) or 'a3' (420×297).
• modelName: title-block name; defaults to the script's file name.
• date: title-block date string; defaults to a placeholder so output stays byte-deterministic (stamp an ISO date when the drawing is released).
• annotations: authored dimensions and notes — see below.
