lint_drawing
Run structural drawing-quality checks to detect label-measured divergence, overlaps, redundant lines, and page-bound overshoot. Identify SVG export issues like native elements. Catches bugs before rendering.
Instructions
Run structural drawing-quality checks and return JSON {violations: [...]}.
Session mode (default): reconstructs the session's annotations and delegates
to build123d-drafting-helpers (lint_drawing + find_interferences) — single
source of truth. Surfaces label-vs-measured divergence (axis swap), Leader
line through its own label, annotation/label overlap, a witness/extension
line piercing a neighbour's label, redundant collinear lines, and page-bounds
overshoot.
SVG mode (svg_path set): scans an SVG file for export-only pathologies — most
importantly native <text> elements (build123d renders glyph paths, so any
<text> won't DXF-export and won't scale with the model).
drawing_scale: when the geometry was scaled up before projecting — e.g. a
7.5 mm feature drawn at 5:1 via part.scale(5) — pass the same factor (5.0)
so the label-vs-measured check divides each measured path length by it
before comparing to the label. This lets labels carry the *real* dimension
while the geometry is drawn enlarged, instead of every dim tripping a false
axis-swap warning. Session mode only; defaults to 1.0 (no scaling).
view_shape_names: list of shape names (from show()) representing the placed
view outlines. Used to detect view_annotation_overlap (annotation bbox
overlaps a view outline) and view_overlap (two view outlines overlap).
Pass the visible-side placed compounds from each projection, e.g.
["front_placed", "side_placed", "plan_placed", "iso"]. Session mode only.
Each violation is {severity, check, object, message}. Run this after major
drawing additions; running it BEFORE rendering catches the bug at the source.
