"""Panel Analysis Handling tab: the "Lifter and Dunnage Detail" plan drawing,
|
|
plus the panel's weight centroid -- pure geometry/arithmetic, both Pythons,
|
|
no Revit, no WPF, no `vibe.panelsketch` import.
|
|
|
|
WHY THIS IS A SEPARATE MODULE FROM `panelsketch.py`: the owner's ruling
|
|
(2026-09-04) was specific about what this drawing has to look like --
|
|
"lift&dunnage detail 画的完全不对。而且太小了。画图的时候，panel 的长度总要占满
|
|
整个显示窗口的宽度，因为不管什么板，你总是横着画" (the old drawing was wrong
|
|
and too small; the panel's LENGTH must always fill the drawing's full width,
|
|
because a panel is always drawn lengthwise no matter what it is) -- a layout
|
|
rule `panelsketch.plan()` does not follow (it letterboxes to whichever axis is
|
|
tighter, so a squat panel can end up far short of the column width). Rather
|
|
than change `panelsketch.plan()` out from under whatever else reads it, this
|
|
is a new, narrower entry point owned by the same module (`vibe.pa_handling`)
|
|
that reads the rest of the Handling tab, so the two stay in lockstep.
|
|
|
|
THE SEAM is identical to `panelsketch.py`'s own: a flat list of drawing
|
|
PRIMITIVES in a normalised, already-in-pixels coordinate space, origin
|
|
top-left, y increasing downward (WPF's `Canvas` convention) -- the WPF
|
|
painting is the button's job. `_clamp_primitive` below guarantees every
|
|
primitive lies inside `[0, width_px] x [0, height_px]`, same discipline as
|
|
`panelsketch._clamp_primitive`.
|
|
|
|
PRIMITIVE VOCABULARY reuses `panelsketch.plan()`'s own kinds on purpose (read
|
|
`panelsketch.py`'s `_clamp_primitive` and the button's `_drawing_canvas` /
|
|
`_draw_primitive` before changing this) so the EXISTING renderer already
|
|
knows how to paint everything here with no renderer change required:
|
|
|
|
{'kind': 'rect', ...} panel outline / openings
|
|
{'kind': 'dot', ..., 'role': 'face-lifter'} a FACE lifter -- the
|
|
renderer already draws
|
|
`dot` as a small filled
|
|
circle.
|
|
{'kind': 'support', ..., 'role': 'edge-lifter', 'edge': 'bottom'|'top',
|
|
'edge_kind': 'end'|'side', 'ambiguous': bool}
|
|
an EDGE lifter -- the
|
|
renderer already draws
|
|
`support` as a filled
|
|
triangle (hollow when
|
|
`flagged`); `edge` names
|
|
which side of the panel it
|
|
sits on ('bottom'/'top' of
|
|
whichever axis `edge_kind`
|
|
says -- the panel's two
|
|
ENDS for 'end', its two
|
|
long SIDES for 'side'),
|
|
same "informational until a
|
|
renderer wants to orient
|
|
the glyph" status as
|
|
before. `edge_kind` and
|
|
`ambiguous` are new
|
|
(2026-09-04) -- see
|
|
`parse_edge_lifters()`.
|
|
{'kind': 'line', ..., 'role': 'dunnage', 'dashed': True}
|
|
a transverse dunnage line,
|
|
paired with a
|
|
`role: 'dunnage-label'`
|
|
text primitive reading
|
|
'Dunnage'. `dashed` is a
|
|
hint the current renderer
|
|
does not read yet (it
|
|
draws every `line` solid);
|
|
carried so a later
|
|
renderer change needs no
|
|
primitive change.
|
|
{'kind': 'text', ..., 'role': 'dimension', 'font_px': 11,
|
|
'stagger': 'inner'|'outer'} a dimension-chain label --
|
|
`font_px` is the same kind
|
|
of forward-compatible hint
|
|
as `dashed` above (the
|
|
current renderer hardcodes
|
|
every `text` primitive to
|
|
10px regardless). `stagger`
|
|
(transverse-chain labels
|
|
only) names which of the
|
|
two columns a close-packed
|
|
label was pushed into --
|
|
see the THIRD ruling.
|
|
{'kind': 'marker', 'glyph': 'cross', 'role': 'centroid'} + a 'CG' text
|
|
the weight centroid, same
|
|
as `panelsketch.plan()`.
|
|
{'kind': 'line'/'text', 'role': 'dimension'} dimension chains, same
|
|
shapes as everywhere else
|
|
in `panelsketch.py`.
|
|
|
|
`role` in `'face-lifter'` / `'edge-lifter'` / `'dunnage'` is the exact
|
|
vocabulary `panelsketch.plan()`'s own docstring already reserved for this
|
|
data the day it existed ("wire it in next to `_parse_opening_row`") --
|
|
matched here for consistency even though the primitives themselves live in
|
|
this module, not that one.
|
|
|
|
INPUT is the same `values` dict `panelanalysisform.py` / `panelsketch.py`
|
|
read from the form -- string-valued, never mutated. Keys read, all optional
|
|
except `length_ft` / `width_ft` (see below):
|
|
|
|
length_ft, width_ft required -- see MISSING INPUT below.
|
|
thickness_in, section_type, wythe_top_in, insulation_in, wythe_bottom_in
|
|
feed `centroid()`'s Y (through-thickness) figure.
|
|
openings_rows same shape `panelsketch._parse_opening_row`
|
|
documents (a list of dicts: 'type', 'pos_along',
|
|
'pos_along_from', 'length', 'pos_vert', 'height',
|
|
'label'). This module only ever needs the
|
|
along-length / through-width axes (a PLAN view
|
|
has no through-thickness axis), so it parses a
|
|
narrower version of that row shape than
|
|
`panelsketch.py` does -- duplicated, not
|
|
imported, for the same "stay a leaf" reason
|
|
`panelsketch.py` gives for not importing
|
|
`panelanalysisform`.
|
|
face_lifters, edge_lifters
|
|
free text, one lifter per line, `'x_ft @ frac'`
|
|
-- `x_ft` along `length_ft` from the start,
|
|
`frac` the fraction of `width_ft` from the
|
|
bottom edge. The exact grammar
|
|
`vibe.pa_lifters.parse_lifter_lines` reads;
|
|
duplicated here rather than imported for the
|
|
same leaf-module reason as `openings_rows` above.
|
|
`edge_lifters` rows are classified END vs SIDE
|
|
by geometry -- see `parse_edge_lifters()`.
|
|
top_edge_lifters, side_edge_lifters
|
|
free text, same `'x_ft @ frac'` grammar as
|
|
`edge_lifters` -- the reads sibling's OWN
|
|
classification of which edge a lifter sits on,
|
|
preferred outright over re-deriving it from
|
|
`edge_lifters` by geometry when either carries
|
|
text. See `parse_edge_lifters()`.
|
|
dunnage free text, dunnage positions in ft along
|
|
`length_ft`, comma/whitespace separated.
|
|
dunnage_positions_ft a list of ft positions along `length_ft`, the
|
|
reads sibling's own dunnage read off Panel
|
|
Lift's job -- preferred outright over parsing
|
|
`dunnage` text when it is a list with at least
|
|
one usable entry. See `dunnage_positions()`.
|
|
There is NO plant-rule fallback reachable from
|
|
this leaf module for either dunnage source (that
|
|
lookup lives in `vibe.knowledge`, which this
|
|
module deliberately does not import -- see
|
|
MISSING INPUT below); neither present means no
|
|
dunnage lines are drawn, and is NOT reported
|
|
from here -- see `dunnage_positions()`'s own
|
|
docstring for why, and `pa_handling.page()` for
|
|
where it is said instead.
|
|
mark, design_number label only, as in `panelsketch.py`.
|
|
|
|
MISSING INPUT IS THE HEADLINE STATE, same law as `panelsketch.py`:
|
|
`length_ft` / `width_ft` missing, blank, non-numeric or <= 0 is the one hard
|
|
stop -- `sketch()`... `lifter_dunnage()` returns `([], problems)`, no panel
|
|
drawn, nothing guessed. Every other gap (no lifters typed, no dunnage, an
|
|
opening row with an unresolved axis, a lifter outside the panel) still draws
|
|
what it safely can and reports the rest, exactly like every `panelsketch.py`
|
|
entry point.
|
|
|
|
THE LENGTH-FILLS-THE-WIDTH LAYOUT (the owner's ruling quoted above) means
|
|
`lifter_dunnage()` does NOT letterbox to whichever axis is tighter the way
|
|
every `panelsketch.py` drawing does -- `draw_w` is always the full available
|
|
width, and `draw_h = draw_w * (width_ft / length_ft)` follows from it,
|
|
true-to-scale but never fit-to-height. The `'aspect'` the caller's `drawing`
|
|
block declares (`width_ft / length_ft`, clamped) is what sizes the
|
|
CONTAINER to roughly match this before this function ever runs, so the two
|
|
are meant to agree; `_clamp_primitive` is still the backstop that keeps
|
|
every primitive inside whatever box actually gets passed in.
|
|
|
|
2026-09-04 SECOND RULING, off a headless render of this tab against a real
|
|
wall (37.58 x 8.375 ft, 8 face lifters, 4 edge lifters all sitting at
|
|
`x == length_ft`), three parts, all folded into this pass:
|
|
|
|
1. EDGE LIFTER CLASSIFICATION was wrong. The old code treated every
|
|
`edge_lifters` row identically -- position it along the top/bottom of
|
|
the PANEL OUTLINE by its `frac` (`<= 0.5` -> 'bottom', else 'top'),
|
|
the same way a face lifter is positioned, just with a triangle glyph
|
|
instead of a circle. For four lifters that all share `x == length_ft`
|
|
that collapses them onto two overlapping points at the panel's two
|
|
right-hand corners -- "the drawing put one triangle at the corner" --
|
|
when what they actually are is four TOP-EDGE (end) lifters spread
|
|
along the short edge at `x = length_ft`, one per transverse fraction.
|
|
`parse_edge_lifters()` below is the fix: an edge lifter whose `x_ft`
|
|
sits within `_END_TOL_FT` (0.5 ft) of 0 or of `length_ft` is an END
|
|
lifter -- drawn ON that end edge (`x` pinned to 0 or `draw_w`), at its
|
|
TRANSVERSE position (`y = frac * width_ft`, continuously, not snapped
|
|
to the panel's top/bottom); one whose `frac` sits within
|
|
`_SIDE_TOL_FRAC` (0.05) of 0 or 1 (and does not already qualify as an
|
|
END lifter -- the x-check runs first) is a SIDE lifter -- drawn on
|
|
that long edge at its longitudinal `x_ft`, the old behaviour. A row
|
|
that fits neither test is still drawn (never dropped) as a side
|
|
lifter by which half of `frac` it falls in, the historical default,
|
|
but comes back with `ambiguous: True` and a `problems` sentence,
|
|
because a "edge" lifter that sits on no edge at all is worth a flag.
|
|
`top_edge_lifters` / `side_edge_lifters` -- free text in the same
|
|
`'x_ft @ frac'` grammar as `edge_lifters`, added by the sibling that
|
|
reads Panel Lift's own classification (`vibe.pa_lifters.
|
|
edge_lifter_lines`) -- are PREFERRED outright over re-classifying
|
|
`edge_lifters` by geometry, when either carries text: a
|
|
`top_edge_lifters` row is always an END lifter (`kind`), but that
|
|
field files BOTH a panel's bottom-end and top-end lifters -- the name
|
|
is a holdover, not a promise -- so `side` still comes from `x_ft` via
|
|
`_end_side_from_x`; a `side_edge_lifters` row is always a SIDE
|
|
lifter, bottom/top chosen by `frac` alone. `pa_handling._lifter_table_block`
|
|
reads this exact same function (through the `psh` it already imports)
|
|
for its own "Face / Side Edge / Top Edge" table groups, so the table
|
|
and the drawing can never disagree about what a given lifter is.
|
|
2. DIMENSION CHAIN READABILITY. Every dimension-chain text primitive now
|
|
carries `'font_px': 11` -- a rendering HINT, same discipline as
|
|
`dashed` on a dunnage line (see the vocabulary list below): the
|
|
current renderer does not read it yet, but a later renderer change
|
|
needs no primitive change to pick it up. The chain itself already
|
|
drew one backbone line plus one tick/label per DISTINCT position
|
|
(`sorted(set(round(..., 3)))`); that discipline is unchanged, and the
|
|
end-edge lifters' transverse positions were already folded into
|
|
`all_y_ft` the same as a face lifter's -- the classification fix
|
|
above did not touch that part. (A live render of THIS fix still
|
|
showed the chain squashed into an illegible ~20px box -- see the
|
|
THIRD ruling below, which is the part that actually fixed it.)
|
|
3. DUNNAGE. `dunnage_positions()` (renamed from the old private
|
|
`_dunnage_positions`, and now a documented sibling of `centroid()`)
|
|
reads `values['dunnage_positions_ft']` -- a list of ft positions the
|
|
reads sibling supplies straight off Panel Lift's job -- FIRST, and
|
|
only falls back to parsing `values['dunnage']` free text when that
|
|
list is absent or every entry in it is unusable. Each dunnage line
|
|
drawn now carries a matching `'dunnage-label'` text primitive reading
|
|
'Dunnage'. And the part that actually changes behaviour: when NEITHER
|
|
source has anything to draw from, this function no longer adds a
|
|
`problems` sentence of its own. It used to ("Dunnage positions are
|
|
not entered..."), and `PanelAnalysis.pushbutton/script.py`'s
|
|
`_drawing_canvas` prints every `problems` entry a drawing function
|
|
returns as a RED inline note directly under the drawing -- so a panel
|
|
with genuinely no dunnage data got a permanent red warning under an
|
|
otherwise-fine picture. `pa_handling.page()` now owns saying so, ONCE,
|
|
as a single quiet sentence elsewhere on the page (see its own
|
|
docstring) -- this function stays silent on the "nothing entered"
|
|
case and reports only a REAL defect (an unreadable list, unparseable
|
|
text) the way it always did.
|
|
|
|
2026-09-04 THIRD RULING, off a LIVE render of the second ruling's own font
|
|
hint fix -- the transverse chain was still a squashed ~20px-wide box of
|
|
ticks, because `font_px` is only a hint the renderer does not act on yet
|
|
and the LAYOUT itself was still cramming the whole chain into the ordinary
|
|
(<= 40 px) margin:
|
|
|
|
1. THE LEFT MARGIN is now reserved specifically for this chain --
|
|
`_left_margin()` returns at least `_LEFT_MARGIN_MIN_PX` (90 px)
|
|
regardless of how small `_margin()` comes out, and `lifter_dunnage()`
|
|
uses it (not the ordinary `margin`) for `ox`. `draw_w` is computed off
|
|
the REMAINING width (`width_px - left_margin - margin`), so the panel
|
|
still fills every pixel that is left over -- the length-fills-the-
|
|
width rule from the FIRST ruling did not change, only what counts as
|
|
"available."
|
|
2. TWO LABELS WHOSE PIXEL POSITIONS ARE CLOSE now stagger into an inner
|
|
and an outer column instead of overlapping: whenever a label's `py`
|
|
falls within `_LEFT_LABEL_STAGGER_TOL_PX` (14 px) of the PREVIOUS
|
|
label's `py` (both walked in ascending-`y_ft` order), it draws at
|
|
`outer_x` instead of `inner_x` (`_LEFT_LABEL_STAGGER_OFFSET_PX`, 34 px
|
|
further from the chain); a label whose neighbour is far enough away
|
|
resets to the inner column. Each label also carries a `'stagger':
|
|
'inner'|'outer'` hint alongside `font_px`, for a renderer that wants
|
|
to draw a short leader line back to its own tick.
|
|
|
|
`centroid()` is the second half of the owner's ruling ("centroid 该算要算的"
|
|
-- if it can be computed, compute it): the panel's weight centroid, X from
|
|
the start and Z from the left (the plan-view, area-weighted centroid,
|
|
identical arithmetic to `panelsketch.plan()`'s own, corrected for `Opening`
|
|
rows only -- a Reveal is partial-depth and a Solid Zone removes nothing, so
|
|
neither reduces the plan-view area) and Y from the bottom (the
|
|
through-thickness centroid). Y is deliberately NOT mass-weighted by each
|
|
wythe's own unit weight for a Sandwich section: `panelanalysisform.py` has
|
|
no established mapping from `unit_weight_pcf` / `unit_weight2_pcf` (wythe 1
|
|
vs wythe 2, a MATERIAL pairing) onto `wythe_top_in` / `wythe_bottom_in` (top
|
|
vs bottom, a POSITION pairing) -- inventing one here would be exactly the
|
|
kind of unverifiable guess CLAUDE.md SS3 rules out, so Y is computed from
|
|
the wythe THICKNESSES alone (half the total, same as a solid section) with
|
|
a `problems` note when the wythe trio is what made that possible instead of
|
|
`thickness_in`. `centroid()` is called both by `page()` (for the printed
|
|
kv block) and by `lifter_dunnage()` (for the marker), so the two can never
|
|
show a different number for the same panel.
|
|
|
|
Standard-library only (`re`, for the dunnage/lifter text splitting) --
|
|
IronPython 2.7 in the button, plain CPython in `tests/`: no f-strings, no
|
|
dataclasses/typing/enum, `'{0}'.format(...)` throughout. `values` is never
|

mutated by anything below.

list with at least one entry that reads as a number; falls back to

parsing `values['dunnage']` free text (one number per line, or

comma/whitespace separated) otherwise. There is no plant-rule lookup

to add a `problems` sentence of its own for exactly this case, and

`PanelAnalysis.pushbutton/script.py` prints every `problems` entry a
|
|
drawing function returns as a permanent RED note directly under the

drawing, so a panel with genuinely no dunnage data got a standing red
|
|
warning under an otherwise-fine picture. `pa_handling.page()` now says
|
|
so once, quietly, elsewhere on the page instead -- this function
|
|
reports only a REAL defect: `dunnage_positions_ft` present but not a
|
|
list, a list entry that will not parse as a number, or `dunnage` text

with an unparseable token. `values` is never mutated.

`length_ft` / `width_ft` are `None` when not entered -- this function
|
|
never invents a placeholder rectangle the way `pa_sketch_extents.
|
|
outline_geometry_ft()` does, because every one of the lists above is
|
|
only meaningful relative to a real length/width and a fabricated pair
|
|
would misplace every lifter drawn against it; the page is expected to
|
|
show "enter length and width" in that case, named in `problems`, rather
|
|
than a picture that looks plausible and is not. Never raises; `values`
|
|
is read-only.
