W-6 registered center · X

68.306003 ft · estimated uncertainty ±1.5 ft

Center of the analytical locator only; not a shaft, hatch or stair centerline.

Calculated from: f4-elevator-2-w6-world-vertex-1-x, f4-elevator-2-w6-world-vertex-2-x, f4-elevator-2-w6-world-vertex-3-x, f4-elevator-2-w6-world-vertex-4-x

W-6 registered center · Z

49.909662 ft · estimated uncertainty ±1.5 ft

Center of the analytical locator only; not a shaft, hatch or stair centerline.

Calculated from: f4-elevator-2-w6-world-vertex-1-z, f4-elevator-2-w6-world-vertex-2-z, f4-elevator-2-w6-world-vertex-3-z, f4-elevator-2-w6-world-vertex-4-z

Physical geometry accepted

Extruding any transformed locator into physical walls, shafts, stairs or rooms. Treating control-fit zero as proof of accuracy. Using the coarse Elevator 3 or stair locator boundaries as clear or outside faces. Replacing unresolved wall, slab, opening or construction thicknesses with defaults.

Cross-sheet registration residual

0.797087 ft · estimated uncertainty ±1.5 ft

Checks the minimum-X side of the broad outer-enclosure trace against the printed east outside face; the face classification still needs a dedicated detail-to-plan overlay. Reference package: elevator-w230-first-floor-east-face-control.
