B3 Zone Location in DXF
The B3 zone is located in the NW corner of the basement level. The building is oriented with coordinates in meters, with the building extending across negative x and y quadrants.
B3 Zone Bounding Area (DXF coordinates)
- X range: approximately -69 to -60 meters
- Y range: approximately -144 to -140 meters
Reference Points
- North wall inner face: y = -139.911 m (from wall polyline, 30cm concrete wall)
- South wall: y = -144.217 m (from dimension entity endpoint)
- East wall: x = -59.956 m (from dimension entity, partition to B313)
Zone Geometry (VERIFIED)
Vertex Coordinates
| Point | DXF X (m) | DXF Y (m) | Zone X (cm) | Zone Y (cm) | Zone X (m) | Zone Y (m) | Description |
| SW | -67.326 | -144.217 | 0.0 | 0.0 | 0.00 | 0.00 | South wall, west end (diagonal base) |
| SE | -59.956 | -144.217 | 737.0 | 0.0 | 7.37 | 0.00 | South wall, east end |
| NE | -59.956 | -139.911 | 737.0 | 430.6 | 7.37 | 4.31 | North wall, east end |
| NW | -68.556 | -139.911 | -123.0 | 430.6 | -1.23 | 4.31 | North wall, west end |
Coordinate system: Zone coordinates use origin at SW corner, X positive east, Y positive north.
Transform: zone_x = (dxf_x + 67.326) × 100 cm; zone_y = (dxf_y + 144.217) × 100 cm
Wall Measurements
| Wall | Length (cm) | Length (m) | DXF Verification | Notes |
|---|
| South wall | 737.0 | 7.37 | SE_x - SW_x = 7.370 m | Entry side, interior partition |
| North wall | 860.0 | 8.60 | NE_x - NW_x = 8.600 m | Concrete exterior, 30cm thick |
| East wall | 430.6 | 4.31 | DIMENSION entity: 430.6 cm | Gypsum partition to B313 |
| NW diagonal | 447.8 | 4.48 | sqrt(123² + 430.6²) = 447.8 cm | Concrete exterior facade |
Diagonal Verification
- Horizontal component: 860.0 - 737.0 = 123.0 cm (1.23 m)
- Vertical component: 430.6 cm (4.306 m)
- Calculated: sqrt(123.0² + 430.6²) = sqrt(15129 + 185416) = sqrt(200545) = 447.8 cm ≈ 448 cm ✓
Shape: Right Trapezoid
- Two parallel sides: South (737 cm) and North (860 cm)
- One perpendicular side: East wall (430.6 cm ≈ 431 cm)
- One angled side: NW diagonal (447.8 cm ≈ 448 cm)
- Right angles at SE and NE corners
- Room WIDENS going north (NW extends 1.23 m west of SW)
Area & Volume
| Parameter | Value | Formula/Source |
|---|
| Gross area | 34.38 m² | ½ × (737 + 860) × 430.6 / 10000 |
| Ceiling to slab | 3.50 m (350 cm) | From scope (gypsum T-bar at 2.90m is removable) |
| Raw volume | 120.3 m³ | 34.38 × 3.50 |
| Float floor deduction | -15 cm | Neoprene pads + plywood |
| Acoustic ceiling deduction | -20 cm | Suspended acoustic panels |
| Effective height | 3.15 m (315 cm) | 350 - 15 - 20 |
| Effective volume | 108.3 m³ | 34.38 × 3.15 |
Note: Using exact east wall = 430.6 cm (from DXF) rather than rounded 431 cm gives area = 34.38 m² vs previous 34.42 m². The difference is 0.04 m² (negligible). For consistency with locked reference, 34.42 m² (using rounded 431 cm) remains the SSOT value.
Width Formula
W(Y) = 7.37 + (Y / 4.31) × 1.23 meters
(Y = distance from south wall in meters, room WIDENS going north)
| Y from south (m) | Width E-W (m) | Width (cm) | Notes |
|---|
| 0.00 | 7.37 | 737.0 | South wall (narrowest) |
| 0.50 | 7.51 | 751.3 | |
| 1.00 | 7.66 | 765.5 | |
| 1.11 | 7.69 | 768.7 | COL-WEST south face |
| 1.36 | 7.76 | 775.8 | Column row center |
| 1.50 | 7.80 | 779.8 | |
| 2.00 | 7.94 | 794.1 | |
| 2.50 | 8.08 | 808.4 | |
| 3.00 | 8.23 | 822.6 | |
| 3.50 | 8.37 | 836.9 | |
| 4.00 | 8.51 | 851.2 | |
| 4.31 | 8.60 | 860.0 | North wall (widest) |
Column Positions (FROM DXF — WRONG X POSITIONS)
CRITICAL CORRECTION: The DXF polylines identified below have correct Y coordinates, correct widths (60cm), correct depths (50/55cm), correct col-to-col gap (333cm), and correct gap to north wall (270cm) — but their
X positions are shifted 71 cm west of the actual positions. The PNG reference dimensions (334 + 60 + 333 = 727) are authoritative for column X positions. The DXF extraction identified the wrong polylines on the COLUMNS & STRUCTURE layer.
CORRECT positions (PNG-derived, now in SSOT-GEOMETRY.md):
- COL-WEST: center (3.64, 1.36)m, faces W:334 E:394 S:111 N:161
- COL-EAST: center (7.57, 1.33)m, faces W:727 E:787 S:106 N:161 (~50cm past east wall, ~10cm visible)
The DXF-extracted values below are preserved for documentation but
DO NOT USE for any calculations.
COL-WEST (Interior Column — Labeled 60×50 in PNG) — X values wrong, shifted 71cm west
| Property | DXF Value | Zone Value | Notes |
|---|
| Size | 60 × 50 cm | width × depth | Confirmed from polyline bounds |
| DXF bounds X | [-65.0863, -64.4863] | | |
| DXF bounds Y | [-143.1113, -142.6113] | | |
| Center (zone) | | (254.0, 135.6) cm | = (2.54, 1.36) m |
| West face | | 224.0 cm | from SW |
| East face | | 284.0 cm | from SW |
| South face | | 110.6 cm | ≈ 111 cm from south wall ✓ |
| North face | | 160.6 cm | from south wall |
| Gap to north wall | | 270.0 cm | ✓ matches PNG |
COL-EAST (Partially Embedded in East Wall) — X values wrong, shifted 71cm west
| Property | DXF Value | Zone Value | Notes |
|---|
| Size | 60 × 55 cm | width × depth | 5 cm deeper than COL-WEST |
| DXF bounds X | [-61.1563, -60.5563] | | |
| DXF bounds Y | [-143.1613, -142.6113] | | |
| Center (zone) | | (647.0, 133.1) cm | = (6.47, 1.33) m |
| West face | | 617.0 cm | from SW |
| East face | | 677.0 cm | from SW |
| South face | | 105.6 cm | ≈ 106 cm (5 cm further south than COL-WEST) |
| North face | | 160.6 cm | ALIGNED with COL-WEST north face |
| Gap to north wall | | 270.0 cm | ✓ matches PNG |
| East face to east wall | | 60.0 cm | Partially extends into east side |
Column Alignment Notes
- Both columns have north faces aligned at zone_y = 160.6 cm
- COL-EAST extends 5 cm further south (55 cm depth vs 50 cm)
- COL-WEST south face at 110.6 cm ≈ 111 cm from south ✓ (PNG reference)
- COL-EAST south face at 105.6 cm ≈ 106 cm from south
Structural Spans at Column Row
| Span | Distance (cm) | Notes |
|---|
| Diagonal wall → COL-WEST west face | 262.7 | At y=1.36m from south |
| COL-WEST width | 60.0 | |
| COL-WEST east → COL-EAST west | 333.0 | ✓ matches PNG "333" |
| COL-EAST width | 60.0 | |
| COL-EAST east → East wall | 60.0 | Partially showing into east side |
| Total room width at column row | 775.7 | W(1.36) = 7.757 m ✓ |
| Center-to-center | 393.0 | Between column centers |
PNG "334" Reference Note
The PNG reference shows 334 + 60 + 333 = 727 as the structural span. The 333 and 60 are DXF-confirmed. The 334 measurement reference point could not be precisely identified in the DXF geometry — at the column row center (y=1.36m), the diagonal wall to COL-WEST west face measures 262.7 cm. The 334 may reference a structural grid line or a measurement convention not directly derivable from B3 zone geometry alone. The key verified spans remain 333 cm (col-to-col) and 60 cm (column width).
