Describe the machine. Get a spec and a model you can build.
ForgeFrame drafts the engineering package — subsystems, hard numbers, bill of materials, assembly order — and constructs a real 3D model in the same pass. Export it or push it straight into your prototype queue.

Or start from a finished machine
The arm, the tracked base, the gantry and the delta are built part by part from CAD of real, working builds — every dimension and mass measured, not guessed. The rest are sized by the same solvers a brief goes through, from makers' published figures: the quadcopter from its motors' thrust tests, the ROV from Blue Robotics' thrusters and housings, the conveyor from Forbo's belt method, the mining rover from the force to cut the ground it digs, the walker and the humanoid from their servos. Open one and change it.
Engineering draft
Subsystems, key numbers, BOM with quantities and materials, assembly order and honest risk notes.
Constructed model
A parametric assembly in millimetres you can orbit, explode, and export as STL or GLB — plus BOM CSV.
Prototype pipeline
Submit a design and track it from review through prototyping to built, with a timestamped history.
Drafting is free and unlimited.
Paid plans add exports, storage and the prototype queue.
