Run on a real P&ID pair (kept outside the repository), the pipe takeoff wrote
an empty table. Three causes, each fixed with a test that failed first:
- Measured on the P&ID, a run still needed equipment tags at both ends,
which only routing on the layout needs. Few pipes on a field P&ID end on
a tagged outline. On the P&ID each piece now goes to the room it lies in:
cut at the room outlines when the P&ID has room faces, else to the
nearest room label. Diameters are kept piece by piece. On the layout a
takeoff that could not route every run now says how many, why, the drawn
length left to the control rows, and that length_source='pid' with
force=True measures on the P&ID instead.
- A TEXT stores its line breaks in caret notation ('6^JROOM'), which
plain() left as it was, so a room label's number read as '6^J...'.
plain() now decodes ^J, ^M, ^I and '^ ', leaving MTEXT stacks
('\S1^2;') alone.
- Labels that only mention a room were read as rooms: a control cabinet
naming the room it serves, or a note pointing into a room. An unnumbered
label that names equipment is no room. Without room faces, when the
drawing numbers its rooms, only numbered labels take pieces.
On the field pair the takeoff now fills its table, and every room key is a
real room number. The comparison with the hand-made workbook stays with
the user's files. README collected tests: 4981. The suite passes (4980, 1
xfailed).

A drawing somebody else made, read back as one report in which every
claim carries its evidence and a confidence; the drawing is never
modified.
- units.py: $INSUNITS against the unit the geometry implies (text
heights, wall thickness, door swings, labelled room areas, overall
size). The header is overruled only when the evidence outweighs it,
and then with a warning that quotes the numbers. Robust extents grow
from the quartile box of entity centres; what never joins is an
outlier, named by handle.
- clusters.py: separate bodies of model-space content by raster,
8-connectivity and box absorption - two copies of one plan are two
clusters.
- describe.py: layers with drawn length and the vocabulary's meaning
(name keyword, else the texts on the layer), equipment tags (one tag
lettered twice beside its symbol merged, repeats flagged ambiguous),
room labels in the wall-layer faces of engineering.arch.faces, text
languages by character class, blocks, layouts, the title block.
- server.py opens SECTION 26 (Understanding & QA) with
drawing_understand: core, read-only, tagged analysis/query. Alias
record, inventory, README release snapshot 242, frozen group sizes
(analysis 13).
