feat(sheet): ISO 5457 frames and ISO 7200 title blocks for A4-A0
SECTION 24 opens with sheet_frame and titleblock_apply. engineering/sheet/frames.py transcribes ISO 216's trimmed sizes, ISO 5457's 20 mm filing margin and 10 mm edges, the grid reference system (an even number of divisions per side, that side of the frame over 50 mm; letters from the top, numbers from the left), the centring marks (trimmed edge to 5 mm inside the frame) and the 10 x 5 mm corner trimming marks. Every one of those numbers is pinned by a test against the clause it comes from, because a wrong margin is visible on every drawing this server makes. engineering/sheet/titleblock.py draws the ISO 7200 block -- 180 mm wide, which is exactly the drawing-space width of a portrait A4, which is why one block fits every size -- and carries the ISO 128-30 projection-angle symbol. Which symbol is which is derived rather than remembered: first-angle projection puts the view seen from the left on the right, and the view of the cone from its small end is the small circle inside the large one, so first angle draws the cone left and the circles right. The old A3 module folds in. apply_iso_a3_titleblock now forwards to apply_titleblock(size="A3", projection=None, zones=False, marks=False), which is the geometry it always drew, and tests/test_engineering_titleblock.py passes unchanged -- that is the regression gate for the fold. No new ActiveX member is called: both tools reach the drawing only through contract members the A3 title block has used on both engines since v1.0 (entity_create_polyline / _line / _circle / _text, layout_list, layout_set_current), so there was nothing to probe live. Declared, not glossed: the zone divisions drawn here are equal, so ISO 5457's allowance for shorter corner fields is not implemented; the division counts, which are what a zone reference quotes, are the standard's. ISO 7200's full optional-field list is not transcribed, only the fields this block has a cell for. Coverage is A4-A0; an unknown size is refused by name with the five it has.

## Why this exists

**A big MCP server is expensive to be connected to.** The full catalog costs a client **59,315 tokens** before it has asked for anything. Discovery mode replaces it with two tools and costs **356**.
|
||||
|
||||
**A drafter searches for `FILLET`, not `entity_fillet`.** Those command names appeared in no tool name or description — `df = 0` against a stock index, not badly ranked but *absent*. The fix was data: an authored corpus of **186 AutoCAD command names and 933 synonym phrases** covering all 204 tools. A test refuses to let a tool exist without one.

**Two rules worth knowing.** Every coordinate in and out of a tool is WCS on both engines — the one exception is TEXT `rotation`, which stays in the entity frame because a mirrored TEXT is mirror-imaged and no scalar angle expresses that. And never read vertices back and shoelace them: that loses **28.2%** of the area on a semicircular edge, silently. `analysis_measure_entity(handle)` reads the real geometry and states its own accuracy.

------

Sheet sizes ISO 216:2007, A series, trimmed sizes in millimetres.
|
||||
Frame and margins ISO 5457:1999, 4.2 -- the drawing frame that bounds the
|
||||
drawing space leaves a 20 mm filing margin on the binding
|
||||
edge and 10 mm on the other three, for every size A4 to A0.
|
||||
Centring marks ISO 5457:1999, 4.3 -- four marks at the middle of each side
|
||||
of the trimmed sheet, running from the trimmed edge to 5 mm
|
||||
inside the frame.
|
||||
Grid reference ISO 5457:1999, 4.4 -- the number of divisions along a side is
|
||||
an even number obtained from the length of that side of the
|
||||
frame divided by 50 mm. Columns are numbered from the left,
|
||||
rows are lettered from the top.
|
||||
Trimming marks ISO 5457:1999, 4.5 -- one mark in each corner of the trimmed
|
||||
sheet, two overlapping 10 mm x 5 mm rectangles.
|
||||
|
||||
COVERAGE: A4, A3, A2, A1, A0. The B series, the elongated sizes (A3.1, A4.2,
|
||||
...) and the untrimmed sizes are not transcribed; `sheet_size` refuses an
|
||||
unknown name and lists the five it has.
|
||||
|

NOT IMPLEMENTED, deliberately, so nobody reads more into the geometry than is
|
||||
in it:
|
||||
|
||||
* ISO 5457's allowance for shorter *corner* fields in the grid. The divisions
|
||||
drawn here are equal (frame side / n). The division COUNT -- the number a
|
||||
zone reference quotes, and the thing that is visible on the sheet -- is the
|
||||
standard's; the two end fields' boundary sits up to 5 mm from where a
|
||||
corner-field layout would put it.
|
||||
* The grid is drawn for A4 too, although ISO 5457 does not require one there.

(`company`), the identification number (`drawing_no`), the

date of issue (`date`), the segment/sheet number (`sheet`) and

the title (`title`). The rest carried here are optional

fields: creator (`drawn_by`), approval person (`checked_by`),

version (`revision`), and the supplementary item data this

shop draws (`part_no`, `material`, `scale`, `units`). ISO

the fields this block has a cell for.
