A UH-1C Huey gunship, part by part
The Vietnam-era Bell UH-1C in its gunship fit — 540 rotor with the stabilizer bar, T53 turbine, skids, quad M60C guns, seven-shot rocket pods and the door gunners' M60s — modelled as exact solids in NativeCAD from the Army's own parts manuals and test reports. Drag to orbit, pinch or scroll to zoom, spin up the rotor, open the doors, explode it by system or cut it open, and pick a close-up.

Download the scene
The same aircraft as a SceneReady export — glTF with a level-of-detail chain and instancing, a STEP AP242 assembly, and the bill of materials from the parts census.
GLBfull detail · instanced fasteners, rockets, links · rotor / door / gun clips
GLB LOD 125 % of the triangles
GLB LOD 25 % of the triangles, for a distant view
STEP AP242 (.stpZ)compressed assembly: a sub-assembly per system, the four loadout configs
BOM (CSV)part number, name, qty, source TM figure, from the parts census
Manifestconfigs XM16 / XM21 x M60 / M60D, joints, clips, sizes, audit record
Gated: the export is written only when the scene audit is clean for every loadout and pose, so these links go live the day it passes.
What we asked for
The whole aircraft started from the requests below. Every prompt is printed word for word, in order, with the answers picked along the way.
-
oh I want a showcase demo of a helicopter designed in NativeCAD / let's do a vietnam era huey as realistic as we can make it down to the m60D's on the side and rocket pods / tons of research, get drawings + manuals
Picked: UH-1C gunship Full build, every part piece by piece -
include in the showcase what we exactly prompted to get the output

How close is it to the real aircraft?
15 of 15 manual dimensions measured on the built meshes are within 1 in or 1 %. Each figure is measured on the placed 3D parts and compared with the Army's published dimensions; the gate is 1 in or 1 %, whichever is larger.
473.6 inLength, nose to tail skid · manual 474 in (−0.4 in)
631.6 inLength, rotors turning · manual 634.8 in (−3.2 in)
152.7 inHeight to mast top · manual 152.4 in (+0.3 in)
529.5 inMain rotor diameter (540) · manual 528 in (+1.5 in)
Furthest from the manual: skid gear width (−0.8 in, −0.8 %); elevator (synchronized) span (+0.7 in, +0.6 %); length, rotors turning (−3.2 in, −0.5 %). Nothing is over the gate.
Silhouette metrics: side 598 x 182 in, fill 24 %; top 216 x 598 in, fill 25 %; front 216 x 182 in, fill 27 %. IoU against the calibrated three-view is pending a host run (reference images stay out of git).

Loadouts
XM16 · the default
Four M60C machine guns on flexible mounts, two each side, with a seven-shot XM158 rocket pod outboard — the most common UH-1C gunship setup, and the one the page opens on.
XM21 · miniguns
The quad M60Cs give way to a pair of M134 six-barrel miniguns, 31.5 in long, on the same XM156 mount, still with the XM158 pods.
Door guns
UH-1C door gunners flew with M60s hung on bungee cords from the cabin roof; the M60D on a fixed pintle belongs to the longer-cabin D and H models, and is here as a switch.
