Project Microsite

Off-Road Camping Trailer

A custom flat-fronted, tapered-prow box trailer. This record holds the design spec, the drawing workflow, the toolchain, and the project assets.

A welded steel box camper with a flat-fronted tapered nose. The body and nose are one continuous shell — the taper is in plan only; the form is full height throughout. Body 1500 × 1500 × 2000, 2500 overall, on a single off-road axle with externally-mounted wheels and a 550W roof solar panel.

Open items. Front-door description was never completed (location, size, full-height?). The 600-from-base belt line is flagged for confirmation — height, extent, or whether it wraps the tapered nose.

Drawing & render

For a dimensioned drawing the right tool is parametric CAD — AI image models approximate and will not hold exact millimetres. CAD draws the GA; the renderers handle photoreal.

3D model

First pass: Meshy text-to-3D from the spec prompt. Rejected — 0/10 against the brief.

Rejected first-pass mesh — Rejected first pass — archived, not the build geometry.

Why it fails (visual gate). The mesh is a rounded wagon blob: curved tumblehome body instead of a square full-height box; a scooped nose instead of the flat-fronted 430 tapered prow; vague embossed doors instead of the 900 / 600 off-centre barn pair; a flapping roof lid instead of a flat, centred solar panel. Text-to-3D held none of the hard dimensions.

Corrective path. One clean orthographic reference from the spec (Nano Banana) → image-to-3D (Meshy / Rodin) for geometry control → export GLB → scale to exact mm in Blender → render in D5 / Twinmotion. Or model the box directly in CAD.

Work log

Session startBrief: architectural drawing of the trailer. Sourced 550W panel dimensions; surveyed AI render + CAD tooling.
GeometryFlat-fronted tapered prow — 430 flat face, full height, centred; body + nose one continuous shell.
Running gear265/70/16 single axle, 800 from rear, 100 below base. Corrected: wheels external / outboard, not under the floor.
Openings & trimThree doors — rear barn pair 900 + 600 off-centre, full height, two RV handles. Edge / vertical / belt trim lines captured.
RoofSolar revised 400W → 550W (2278 × 1134 × 35), centred front-to-back.
ToolingHand-coded drawings drifted on precision. Decision: lock numbers in spec, model via prompt-to-3D, render in D5 / Twinmotion.
3D modelFirst mesh generated via Meshy text-to-3D from the spec prompt.
