Product Design & CAD Services
CAD models, engineering drawings, and DFM analysis that turn your idea into something a shop can actually build — done by real engineers, not a template generator.
Book Free Design ReviewWho this is for
You have a sketch, a rough prototype, or just an idea, and need real engineering behind it
You're a startup that needs investor-ready CAD and documentation
You're redesigning an existing product to cut manufacturing cost or fix a design flaw
You don't have in-house mechanical engineering and need a partner who does
What you get
Full 3D CAD models — STEP, IGES, and native SolidWorks/Fusion 360 files
2D engineering drawings with GD&T call-outs
A complete bill of materials (BOM)
DFM analysis and manufacturing method recommendations
Photorealistic product renders
An engineering sign-off memo documenting key decisions
What it actually costs
Design work starts around $2,000. A typical project runs $3,000–25,000 depending on complexity — a single molded part costs a lot less than a multi-part electromechanical assembly.
Our Design Process
Discovery & Requirements
We start with a deep-dive session to understand your product goals, target users, functional requirements, budget, and timeline — before touching CAD.
Concept Sketching
Multiple design directions are sketched and presented. You choose the direction — or we blend the best elements — and move forward with a single agreed concept.
CAD Development & DFM Review
The concept is developed into full 3D parametric CAD, with a DFM pass flagging anything that would increase manufacturing cost or complexity unnecessarily.
Documentation Package
Complete engineering drawings, BOM, and supporting files are produced and delivered. You own everything.
Not sure you're ready for the design phase?
Run your idea through our free Reality Check — an engineer's two-minute read on what's solid, what's unknown, and what design would pin down first.

"Working with RMA was a game changer for Shifters Eyewear. As a startup founder, I needed a partner who could take my design sketches and turn them into a real, manufacturable product. Reid guided me through every phase with patience and precision."
