**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.

"""ISO annotation symbols: surface texture (ISO 21920-1 / ISO 1302) and welds (ISO 2553).
|

|

Pure geometry. Every function here returns primitive *descriptions* from
|
||||
`engineering.mech.primitives` in a symbol-local frame whose origin is the point
|
||||
the leader attaches to; `draw_*` is the only async part and the only part that
|
||||
touches a backend. That split is what lets a test assert the emitted tuples
|
||||
instead of a screenshot.

|
||||
SOURCE - surface-texture symbol proportions: ISO 1302:2002, "Geometrical
|
||||
Product Specifications (GPS) - Indication of surface texture in technical
|
||||
product documentation", the table of graphical-symbol dimensions (text height
|
||||
h -> line width d', short-leg height H1, minimum overall height H2). The seven
|
||||
rows below are transcribed from it. ISO 21920-1:2021 superseded ISO 1302
|
||||
without changing the graphical symbol, so the same proportions serve both
|
||||
designations. The clause/table *number* is deliberately not quoted: the values
|
||||
are what this implementer can state, the numbering is not, and a fabricated
|
||||
citation is worse than none. A text height outside the seven rows is refused
|
||||
by name - never interpolated.
|
||||
|
||||
SOURCE - direction-of-lay symbols: ISO 1302:2002, the seven symbols for the
|
||||
direction of lay (=, perpendicular, X, M, C, R, P). A lay name outside those
|
||||
seven is refused with the list.
|
||||
|
||||
SOURCE - weld symbols: ISO 2553:2019, "Welding and allied processes -
|
||||
Symbolic representation on drawings - Welded joints", elementary weld symbols,
|
||||
plus its rules for the reference line, the dashed identification line, the
|
||||
size written before the symbol, the length and pitch written after it, the
|
||||
field-weld flag and the all-around circle at the kink, and the tail carrying
|
||||
the process reference. SIX elementary symbols are transcribed here: square (I),
|
||||
single-V, single-bevel, single-U, single-J and fillet. The rest of the
|
||||
elementary table - spot, seam, plug/slot, backing run, surfacing, edge,
|
||||
steep-flanked V and bevel, fold joint, inclined joint - is NOT shipped,
|
||||
because their drawn form could not be verified; a weld kind outside the six is
|
||||
refused with the list of the six. A narrow catalogue is merely narrow; a
|
||||
guessed weld symbol is a wrong instruction to a welder.
|
||||
|
||||
DECLARED, not transcribed. Neither standard dimensions these, so they are this
|
||||
implementation's stated choices and are named as such wherever they are used:
|
||||
the all-around circle radius, the field-weld flag, the identification line's
|
||||
dash pattern and its offset from the reference line, the text line pitch and
|

the character-width estimate used to size the extension line and lay out the

weld annotation.

"""Centre marks, the cutting-plane line and the material hatch.

|

Pure geometry: these functions return primitive descriptions from
|
||||
`engineering.mech.primitives`; the `draw_*` functions are the only async part
|
||||
and the only part that touches a backend.
|
||||
|
||||
SOURCE - centre marks and centre lines: ISO 128-23, "Technical drawings -
|
||||
General principles of presentation - Lines on construction drawings", which
|
||||
draws a centre line as a long-dash-dotted line that overruns the feature's
|
||||
outline by a short amount. The *dash pattern itself is not written here*: the
|
||||
prims are plain LINE entities on the CENTER layer, whose CENTER linetype
|
||||
(bootstrapped by `drawing_new`) supplies the standard's dash proportions. That
|
||||
is deliberate - transcribing a dash table this module cannot verify would put
|
||||
an invented pattern next to a real one.
|
||||
|
||||
SOURCE - the cutting-plane line: ISO 128-40, "Technical drawings - General
|
||||
principles of presentation - Basic conventions for cuts and sections": a
|
||||
long-dash-dotted line that is *wide* at its ends and at every change of
|
||||
direction, an arrow at each end pointing in the direction of viewing, and the
|
||||
same capital letter at both ends. Line width is a layer property here, so the
|
||||
wide ends are emitted on the `visible` role and the thin middle on the
|
||||
`center` role - the wide/narrow contrast, expressed in the role vocabulary
|
||||
this repository already has.
|
||||
|
||||
The two widths are not numbers this module picks: they are whatever
|
||||
`engineering.layers.ENGINEERING_LAYERS` gives GEOMETRY and CENTER. MEASURED
|
||||
on a drawing `drawing_new` bootstrapped:
|
||||
|
||||
GEOMETRY is 0.50 mm, CENTER is 0.18 mm, a ratio of 2.78:1.
|
||||
|
||||
That measured pair is what is stated here - not the standard's own
|
||||
wide:narrow ratio, which this module does not transcribe.
|
||||
A ratio quoted from memory beside a measured one is exactly the invented
|
||||
number the SOURCE blocks above refuse to ship, and an earlier revision of
|
||||
this block did ship one (it said CENTER was 0.25 mm and the pair 2:1; both
|
||||
were wrong). `tests/test_mech_marks.py` now pins these three figures to
|
||||
`ENGINEERING_LAYERS`, so the sentence cannot drift from the layer set again.
|
||||
|
||||
DECLARED, not transcribed: ISO 128-40 says the ends are thickened and that
|
||||
arrows are placed there; it does not dimension them. The end-segment length,
|
||||
the arrow shaft length, the arrowhead size and the label offset below are this
|
||||
implementation's stated choices, expressed in text heights.
|
||||
|
||||
The material hatch is not authored here at all: it comes from
|
||||
`engineering.mech.standards.materials.hatch_for`, which carries the ISO 128-50
|
||||
map and its own refusal.
