# Source: reference/user_blueprint.jpg (1408 x 768 px), an AI-drawn sheet "DEEP SEA EXPLORER - SUBTUB CLASS, ORTHOGRAPHIC
# BLUEPRINT DS-ST-001" (TOP, SIDE, BOTTOM, FRONT ELEVATION, BACK ELEVATION, two SECTION A-A: COCKPIT INTERIOR), sent with
# "create me 3d model of this tender from this blueprint exactly". Every number below is a pixel of the ORIGINAL picture,
# read on 4-10x zooms with rulers (reference/z4_*.png, build/gr_zoom.py), white-line runs per column and row (red channel
# > 105: the lines are 1.5-2 px wide, the grid R 15-60, the blue ground R 0-25), circle fits (build/gr_circles.py), closed
# regions (build/gr_regions.py) and the flood-filled silhouettes (build/gr_trace.py, gr_views.py ->
# reference/mask_*.png, lines_*.png, build/outline_tables.json). "line" = the centre of a drawn line; "edge" = the outer edge
# of the silhouette (0.75 px outside the outline's centre).
#
# VIEWS AND AXES
#   SIDE  (sheet x 430-1010, y 255-520): the STARBOARD side, nose to the RIGHT (+x), up = -y. SIDE RULES (the user's rule).
#   TOP   (x 440-1000, y 20-250): nose to the right; the upper half of the image is PORT. Centre line y 149.0. Same x as SIDE at
#         the stern (drum 516-543 in both) and at the nose face (912-916); its ring is drawn 6.8 px forward of SIDE's
#         (760.2 vs 753.4): plan positions are taken from SIDE where SIDE shows the part, widths from TOP.
#   BOTTOM(x 440-1000, y 520-745): a near copy of TOP (an AI sheet); used only for what neither SIDE nor TOP show
#         (the ventral port, the skeg's root, the transducer).
#   FRONT (x 95-385, y 215-550): looking aft at the nose; viewer's right = PORT. Same vertical scale and datum as SIDE (drum
#         centre 426.2 vs 425.3, pods 455.4, bottom 476.5 vs 476); horizontally 1/0.941 of TOP's (max hull width 153 px vs
#         144): lateral = (x - 231.85) * 0.941 TOP px.
#   BACK  (x 1075-1345, y 235-550): looking forward at the stern; viewer's right = STARBOARD. Vertical = SIDE's (duct centre
#         377.9 vs drum 379.1); horizontally 1/0.935 of TOP's: lateral = (1205.9 - x) * 0.935 TOP px.
#   SECTION A-A (top right, x 1040-1360, y 20-240): the full hull section at the ring, looking forward, drawn 1/1.346 of SIDE
#         vertically and 1/1.31 of TOP laterally (its ring top y 70 = SIDE 294, its circle r 55.7 = the hull's 73 px half
#         width, its bottom skids y 200 = SIDE 469 = the pods). The bottom-left SECTION A-A (x 150-315, y 565-710) is
#         another AI take of the same cabin: used only for the curved overhead console panels.

#   "1:100 (at A1 size)" is not a usable scale. 10.4 to 36.5 mm/px: no label set can be trusted; the two pairs that agree
#   (TOP 2800/2100: 19.4/20.5; the stern drum's 1850/1890: 23.1/23.6) disagree with each other.
#   The one hard size is the docking interface: the arm's claws close round a collar of the Kazah's profile (wall r 0.506-
#   0.535, hook lip r 0.552, lip top z 1.375; claws shut at r 0.558-0.693, never below z 1.213; landing feet z 1.405 over
#   r 0.41-0.53). The sheet's top ring, read in TOP as three circles round (760.2, 149.0): r 38.89 (its footprint on the
#   hull), r 32.19 and r 29.63 (the thick double line of its top face). At 0.0171 m/px: 0.665, 0.5505, 0.5067 m: the drawn
#   ring IS the Kazah collar (inner wall 0.506, lip 0.552) within 1.5 mm. At 20 mm/px the claws would land on the ring's top
#   face (r 0.59-0.64) and the clips would need their own hardware inside a smaller hatch than drawn.
#   Result: 7.42 m from the stern duct to the sensor drum's face, 2.46 m hull width, 2.71 m over the thruster pods,
#   2.95 m hull height (3.11 m to the collar's lip, 3.55 m to the antenna tip). Moon pool (estimated from the Mako's and
#   Spearfish's results: about 1.1 m left at 4.64 m aft of the origin): the stern face is 3.97 m aft -> about 1.7 m left;
#   the Coder's sweep_check gives the real number.
#   Checked independently on the user's concept render (reference/user_concept.jpg, 2026-10-22, "Check this picture as a
#   referance": the same sub with two pilots): the side window is about 3.2 head heights tall (0.74 m for a 0.23 m head)
#   -> 0.74 / 44 px = 16.8 mm/px; the hull height against the heads -> about 17.5 mm/px. Both agree with 17.1.
#   (A first reading at 14 mm/px from the section's seat heights was dropped: the section is the least careful drawing
#   and its seats come out tall at any scale that fits the docking collar and the concept's pilots.)
#   History: this file was written by two copies of the Designer on 2026-10-22 (02:43-03:01, the Administrator's
#   mistake); reconciled at 03:05 by the remaining one: one set of scripts (gr_trace.py -> gr_views.py -> gr_sil_tables.py,
#   gr_tracecheck.py), S = 0.0171 kept, sections 4, 5, 6, 7, 10 and 12 revised for the concept render.
#
# ORIGIN AND AXES (the Kazah's): 1 unit = 1 m, nose to -Y, port +X, Z up; origin on the centre line 9 cm behind the clamp
#   axis. Clamp axis = the ring's centre: SIDE x 753.40 (the collar's side walls 721/786 at y 297, 716/790.5 at its foot),
#   TOP lateral 0. Origin at SIDE x 753.40 - 0.09 / S = 748.14.
#   z: the collar's lip top must be z 1.375 (the Kazah's). Drawn, the top face's edge is SIDE y 296 and the hull under the
#   collar y 303.6: with y 296 = 1.375 the hull's top at the clamp axis would be z 1.245 and under the claws' inner tips
#   (r 0.558 on the diagonals) z 1.19, only 2.3 cm below the claws' lowest point (1.213). The collar is therefore built
#   1.75 px (0.03 m) taller than drawn: its lip top is image y 294.25 -> Z0 = 294.25 + 1.375 / S = 374.66. Hull top at the

# the nose's starboard side window and the big front window (two pilots side by side behind them), the deck with the two

# pod's lamp beside the drum).
