Project Microsite · Brief
Freelancer brief — 3D model & GA drawings
Produce an accurate, editable 3D model and dimensioned general-arrangement drawings of a custom off-road camping box trailer, built strictly to the locked spec below.
Scope
Model the trailer as a clean parametric CAD solid to the dimensions in SPEC v1.3 (all millimetres, exact). This is the as-built box trailer — flat-fronted tapered prow, two rear barn doors, one front door on the right-hand tapered face, externally-mounted wheels, roof solar, aluminium trim. The styling explorations on the concepts / shaping pages are not part of this brief unless explicitly called out.
Deliverables
| Item | Format |
|---|
| Parametric 3D solid (editable, feature tree) | STEP + native (Fusion / SolidWorks / FreeCAD) |
| Mesh for render | GLB or OBJ |
| General-arrangement drawing — plan, front, side, rear, dimensioned | PDF (1:20) + DWG/DXF |
| Exploded / assembly view (frame + ACP panels + doors + axle) | PDF |
| One clean studio render of the model | PNG, 2K |
Accept criteria. Every dimension matches SPEC v1.3 to ±0; model is watertight and editable by parameter; doors, wheel positions and trim lines are placed exactly per spec; STEP opens clean in a third-party CAD package.

Open item to confirm with client before drawing: belt-line extent — does it wrap the tapered nose?

Terms
Milestone 1: GA drawing for sign-off. Milestone 2: parametric model + STEP/GLB after GA approved. All files and IP transfer to client on final payment. Quote fixed price + turnaround against the deliverables table.
