The takeoffs were run again on a real P&ID pair (kept outside the repository)
and compared with the hand-made workbooks. The user chose how three gaps
should close:
- Rooms drawn as frames. A room label that no wall face holds takes the
smallest closed, straight-sided polyline around it, provided it holds no
other room number and is at least ten label heights a side (label+frame,
0.8). A P&ID draws its rooms this way, so P&ID lengths are now cut at the
frames rather than sent to the nearest label. An unnumbered mention inside
a frame ('hot room') does not deny it.
- The nearest panel, flagged. cable_takeoff(panel_rule="nearest") is the
default: a load that no callout places takes the nearest panel on the
layout, among names with a panel prefix (is_panel_name: CP, JB, DB,
MCC ...) or names a callout gives. The row is flagged panel_inferred, and
an inferred panel never makes a package. panel_rule="stated" keeps the old
behaviour. The takeoff_roundtrip gate and the cable correctness check read
stated panels only: a guess is no evidence.
- Possible packages and detail copies. pipe_takeoff reports detail_copies:
compact groups of tags drawn twice (repeated), and compact groups of one
equipment's own parts, such as M150B, M150C and M150D of M150 (family). A
vendor package or an equipment detail shows up this way. Nothing is
removed until exclude_regions names a region. The runs left out go to the
control rows as excluded_region and to excluded_m. The workbook's method
sheet names the regions.
Each change has a synthetic test that failed first. Suite: 4986 passed, 1
xfailed. The inventory and the document numbers match (README: 4987
collected).
