НОМТ tower: 3D model and walkthrough, checked against the drawings

The model was built from measurements extracted from the architect's drawing set and cross-checked against the Revit DWG. Every window and door position, width, sill and head traces back to a sheet, and every check below ran automatically and passed.

Drawing set: Номт хэвлэх 2-11 БА · 70 sheets
CAD: Revit DWG export · floors 1–9
Posters: compass poster · types A–H
Scale: plan 1:100 · elev. 1:200
Modelled: floors 1–15, tech floor, crown, site

Final render. Native 1920×1080, 16 samples, denoised (a compressed copy plays here; the full-quality file is deliverables/video/nomt-walkthrough.mp4). It shows all four sides, the south wing's "open book" LED screen, four flats (A, B, C, D) and the typical-floor cutaway.

What was checked

all passing

346/346

checks while extracting windows, doors and balconies from the PDF

38/38

cross-checks between the PDF and the architect's DWG

25 mm

RMS fit of 34 doors, DWG vs PDF; the 32 flat doors agree within 12 mm

±10–30 mm

window frames on the elevations vs openings on the plan

0.5 mm

worst residual of the height calibration (19–20 level markers per sheet)

8.5 mm

median wall-face offset, model vs DWG wall lines

Camera paths are planned through the flats' free floor space and sampled every 5 cm against walls, furniture and open door leaves; every frame's view is also tested so the camera never stares into a wall.

Doors are entrance ДХ-2 (1050) + bedroom ДХ-3 (950) + WC ДХ-4 (850). Living windows: casement | fixed | casement, heights in metres above the floor. Balconies are enclosed, 3.0 × 1.6 m clear, glazed 0.89–2.31 m over a parapet. Floor 15's living windows are drawn 0.135 m taller; the model follows that.

To confirm with the architect

found by the checks

Ц-2 height. The p19 table says 1500; Ц-2's own detail (20 + 1350 + 30) and elevation p18 say 1400. Modelled 1400. p19 · p18
“Ц-3” means two things. p18 tags the living-room window vents Ц-3; p19's Ц-3 is the balcony door-window. Each drawing's geometry was followed; the living-room window is not in the schedule. p18 · p19
Flat G balcony opening. The p11 dimension string gives 1980 + 1220; the DWG and the p19 schedule give 2000, like the other seven. Modelled 2000. p11 · DWG · p19
Balcony glazing Ц-5 / Ц-6 is tagged on the plans and p33 but missing from the p19 schedule. p11 · p33 · p19
Bronze colour. CMYK 37/52/19/0 on the sheets converts to mauve, while the drawing fill reads bronze-beige. Rendered as bronze. p16–p18 legend
"Open book" outline. Plans p5–p7 draw a second, thin outline 0.5 m outside the screen's thick outline; the east elevation p17 and the 1250 mm dimension match the thick one. Modelled on the thick outline. p5–p7 · p17
Choices made for the visualisation (not in the drawings): bedding, lamps and cushions (the beds and nightstands themselves are from the DWG); WC doors shown closed; 11 Revit furniture pieces (10 wardrobes, 1 kitchen unit) moved 4–10 cm out of walls they overlapped; balcony frame colour, surrounding blocks and trees are placeholders; the LED screen shows a placeholder "НОМТ ТӨВ". logged in scene_spec.json

How it was built

tools/

Plan chains, door cut-outs and tags on p10/p11 give every opening; elevations p16–p18 give frames, sills and heads (extract_openings.py).
The Revit DWG gives each door and window as a named element; a fitted transform compares both sources (extract_dxf.py, verify_sources.py).
Walls, windows, doors, balconies, fins and the architect's furniture become a checked scene spec (scene_spec.py, furniture_spec.py, massing_spec.py).
Blender builds and renders it; orthographic renders are overlaid on the sheets (blender_build.py, overlay_check.py).
Camera paths are planned and checked through free space; frames render in EEVEE and are cut with Mongolian titles (shots.py, render_shots.py, edit_video.py).

The film itself is the Blender render. Higgsfield was used only to upscale it to 4K (Topaz) — the frames still come from the model, so windows and doors cannot drift. A photoreal AI restyle of the approach was tested and kept out of the film: trees popped in and the surrounding city was invented.
