"""How many physical pieces one mark is. The control-number multiplier. No Revit.
|
|
|
|
WHY THIS IS ITS OWN MODULE
|
|
---------------------------
|
|
It is the single number that decides whether the takeoff is right, and there
|
|
is more than one place it can come from. An assembly is a MARK, a mark is one
|
|
drawing, and the pieces on the floor are the pieces the mark issues.
|
|
Identical pieces share a mark, so counting marks under-orders every material
|
|
in the job.
|
|
|
|
How badly is measurable off an exported ticket set without opening Revit:
|
|
151 tickets, 71 distinct marks. The heaviest mark in that sample issued
|
|
eighteen tickets. A per-mark takeoff of that sample would have ordered 71
|
|
pieces' worth of hardware for 151 pieces -- IF one ticket is one piece there,
|
|
which is a declared fact and not this module's to assume. See the ticket-unit
|
|
section below; it is the reason a ticket set can be read to two different
|
|
numbers.
|
|
|
|
THREE SOURCES, RANKED, AND THE RANKING IS THE POINT
|
|
----------------------------------------------------
|
|
control_numbers the control numbers carried by the model's own
|
|
elements, grouped by mark. AUTHORITATIVE: a control
|
|
number is one physical piece, and this is where they
|
|
actually live. Measured on this job by the job
|
|
reconciliation: 2480 control-numbered elements ->
|
|
1776 pieces, against 755 assemblies. They sit on
|
|
STRUCTURAL FRAMING; walls, floors, columns,
|
|
foundations and generic models were swept -- 17,239
|
|
elements -- and carried none.
|
|
ticket_files the exported tickets, named <job>-<control>_<mark>.
|
|
Only covers marks that have been ticketed, so it is a
|
|
cross-check rather than a source -- and a very good
|
|
one, because it is ground truth for the marks it does
|
|
cover.
|
|
assembly_instances how many assembly instances share the mark's name.
|
|
MEASURED AND FOUND USELESS ON THIS JOB, and kept only
|
|
because it is useless in a way worth recording: 755
|
|
assembly instances, 755 distinct names, not one
|
|
duplicate. It therefore returned 1 for every mark,
|
|
which made every per-job figure silently equal its
|
|
per-mark figure -- the exact undercount this module
|
|
exists to prevent, wearing the costume of a sourced
|
|
number. It now REFUSES to emit a count of one (see
|
|
`from_assembly_names`), so on a job like this one it
|
|
contributes nothing at all and the marks it cannot
|
|
speak for stay visibly `assumed_one`.
|
|
|
|
Anything none of them covers is 1 with basis `assumed_one`, which the report
|
|
prints as an UNDERCOUNT rather than as a quantity. A multiplier nobody could
|
|
source is not a multiplier of one -- and the reason that rule was worth
|
|
writing is that it is what caught `assembly_instances` being wrong.
|
|
|
|
WHAT ONE TICKET IS, AND WHY THIS MODULE MAY NOT DECIDE IT
|
|
----------------------------------------------------------
|
|
`ticket_files` is a piece count only where ONE TICKET IS ONE PIECE. That is
|
|
not universal and it is not this module's to assume: some plants issue one
|
|
ticket per control number, and some issue one ticket covering a whole mark --
|
|
one drawing, one sheet, a QUANITY field and several control numbers printed
|
|
on it. The same export folder read under the second arrangement gives one
|
|
filename per mark, and counting those filenames as pieces would return a
|
|
confident 1 for a mark that is really seven. That is exactly the
|
|
`assembly_instances` failure in different clothes, and it is why the ranking
|
|
above stops being a constant here.
|
|
|
|
So the fact is DECLARED, in `nomenclature.ticket_unit`, and read out of the
|
|
knowledge layers rather than compiled in. `takeoffgather.run` does the read,
|
|
with the literal path, and hands the value to `counting_plan()` below, which
|
|
turns it into the ranking this run is allowed to use and one sentence saying
|
|
why. Three states, and all three are printed:
|
|
|
|
control_number one ticket per control number. A ticket IS a piece, so
|
|
all three sources rank exactly as `ORDER` says.
|
|
piece_mark one ticket covers the mark. A ticket filename is not a
|
|
piece count, so `ticket_files` is WITHDRAWN and the
|
|
ticket-against-model cross-check stands down with a
|
|
sentence rather than reporting every mark as a
|
|
disagreement.
|
|
not declared nobody has said, so this run does not know which of the
|
|
two it is looking at. `ticket_files` is withdrawn HERE
|
|
TOO, and the refusal names the key to declare.
|
|
|
|
That last one is the only judgement call in this file and it goes the way
|
|
this codebase's other unset switches go -- `rails.left_rail_is_fixed`,
|
|
`takeoff.not_ordered`, `notes.instruction_views`. Falling back to
|
|
"one ticket is one piece" would be a guess that can only ever UNDER-count,
|
|
and it would arrive wearing a source's name (`ticket_files`) rather than
|
|
`assumed_one`. Withdrawing the source instead costs nothing that was known:
|
|
the marks it covered fall to `assumed_one`, which the report already prints
|
|
as an undercount in those words. A number that says "could not judge" is a
|
|
different thing from a number that says "judged, found one", and the whole
|
|
point of this module is that the two must never look alike.
|
|
|
|
ONE PARSER FOR ONE RULE
|
|
------------------------
|
|
A control field may hold a range: `50120-50123` is four pieces, not one
|
|
token. `jobrecon.expand_control_field` already implements that expansion,
|
|
with its dash normalisation and its 500-wide sanity cap, and this module
|
|
CALLS IT rather than reimplementing it. Three implementations of one parsing
|
|
rule is how they come to disagree.
