Functional 3D CAD Industrial Model

I have a set of unfinished 3D CAD designs hand-sketches and rough 2D drawings for an industrial product and I need them translated into a single, production-ready 3D CAD model. The design includes moving parts, so I require full representation of the functional components and mechanisms—nothing overly ornamental, just an accurate, mechanically correct build.

You’ll receive unfinished 3D CAD step other format files, the scanned sketches, dimensional notes, and a short explaining instructions or video call if preferred. Feel free to use Onshape, SolidWorks, Inventor, Creo, Fusion 360 or any other parametric platform, as long as the finished file is exported to STEP and remains fully editable.

Deliverable
• A complete 3D CAD assembly in STEP format (showing all functional parts, mates/joints, and clear naming of each component)

Acceptance criteria
• All key dimensions match my drawings (±0.2 mm tolerance)
• Moving parts articulate correctly when the model is tested in CAD
• No unresolved mates, missing references, or suppressed features in the final file

Once the initial model is ready, I’ll review it and share any minor tweaks; one round of revisions is anticipated before sign-off.
