Bundled drawing templates

Five templates, built by the server's own tools — never hand-edited — and listed by drawing_template_list. Start from one with drawing_new(template="iso_a3_mech").

name	standard	sheet	layer set	styles	page setup
iso_a3_mech	ISO	A3 landscape, ISO 5457 frame + ISO 7200 title block	mech	ISO-25 / ISOCP	ISO_A3, monochrome.ctb, 1:1
iso_a1_arch	ISO	A1 landscape	iso13567	ISO-25 / ISOCP, annotation scale 1:50	ISO_A1, monochrome.ctb, fit
iso_a3_pid	ISO	A3 landscape, ISO 5457 frame + title block	pid	ISO-25 / ISOCP	ISO_A3, monochrome.ctb, 1:1
ansi_b_mech	ANSI (metric)	ANSI B landscape	mech	ANSI / ROMANS	ANSI_B, monochrome.ctb, 1:1
ansi_d_arch	ANSI (metric)	ANSI D landscape	iso13567	ANSI / ROMANS	ANSI_D, monochrome.ctb, fit

The two files per template

• <name>.dxf — the headless twin. Produced by uv run --frozen python scripts/build_templates.py, which runs drawing_new → apply_layer_set → styles → drawing_settings → layout rename → titleblock_apply_iso_a3 (A3 sheets) → page_setup_apply → drawing_save_as. scripts/build_templates.py --check rebuilds into a temporary folder and fails if any committed DXF differs (the save-time stamps $TDCREATE, $TDUPDATE, $FINGERPRINTGUID, $VERSIONGUID and the two EZDXF_META entries are masked; everything else must be byte-identical). tests/test_templates.py runs the same check.
• <name>.dwt — the live twin, used by drawing_new(template=…) on the COM backend. AutoCAD's DWT is a DWG container, which no headless library writes, so these are produced on the live machine by uv run --frozen python scripts/smoke_settings_com.py --build-dwt (Task 24's smoke): it opens each DXF over COM and calls drawing_template_save(…dwt) (SaveAs(path, ac2018_Template)), then the files are committed once. While a .dwt is missing, resolve_template falls back to the DXF and reports source: "bundled_dxf"; drawing_template_list shows files.dwt.present. The live engine does not open that DXF blank: Documents.Add accepts only a genuine DWT (measured on AutoCAD 2026), so the COM drawing_new converts the DXF through SaveAs(…, ac2018_Template) once, caches the result under the temp folder keyed on path, size and mtime, and reports template_dwt: {path, cached}.

Line endings: ezdxf writes CRLF and .gitattributes pins templates/*.dxf to CRLF so a checkout on any platform equals a fresh build.

Rebuild after changing anything the build depends on (layer sets, the title block, the dimension presets, the settings facade) and commit the result together with the change — the reproducibility test is the gate.
