I’m commissioning a full-fidelity 3D CAD model of a converted 747 freighter. The aircraft must accommodate a double-height cargo bay sized specifically for standard 20-foot ISO containers, so the internal volume and loading sequence drive the whole project. I need every structural and visual element—including textures and materials—so the file is ready for engineering, VR review, and marketing renders without further adjustment. Core parameters you’ll be working with • Four GE combustion engines (classic pod layout) on a fixed-wing platform • Slimmed window count appropriate for a freighter conversion • Three-crew flight deck moved slightly forward; compact cockpit fittings to free up fuselage space • Pinned flooring and reinforced inner stabiliser tying directly into the container supports • Geometry, mass properties, and safety envelopes aligned to current EASA CS-25 requirements Because cargo area configuration is the priority, I need clear modelling of pallet rails, roller tracks, restraint systems, and door clearances showing how the double-stacked containers load and lock. External surfaces still matter, but devote the most polish to the interior bay. Deliverables 1. Native CAD assembly (SolidWorks or CATIA preferred) plus STEP and IGES exports 2. High-resolution renders highlighting container loading, cockpit, and tailplane structure 3. Basic compliance memo cross-referencing the model’s main features to EASA CS-25 clauses on cargo, access, and floor loading All geometry must be watertight, hierarchy organised logically, and materials labelled so downstream CFD and FEA teams can drop the model straight into their toolchains. If this sounds like your field, let’s discuss timeline and any additional reference data you need.
