CAD Design & Reverse Engineering

Turn a sketch, photo, or physical part into a printable, editable CAD model.

Don't have a file yet? Our engineers can model your idea from reference photos, measurements, or a physical sample — reverse-engineering a part that's no longer sold, or turning a rough idea into something printable.

What people cad design with us

Illustrative examples of what's possible. See real past work.

Replacement parts from a photo
A broken part with no file anywhere — send photos and measurements and we'll rebuild it.
Reverse engineering a physical sample
Bring or ship us the part and we'll measure and model it to match.
Idea to printable model
Sketches or rough dimensions turned into a parametric, editable CAD file.
Capabilities

What we deliver

Every job is scoped in a consultation first — pricing depends on complexity.

STEP & STL deliverables

What to prepare

Reference photos

Multiple angles, in focus, with a ruler or known-size object in frame for scale.

Measurements

Key dimensions if you have calipers or a tape measure on hand — the more precise, the fewer follow-up questions.

What it needs to do

Tell us if the model needs to fit another part, hold a load, or just look right — it changes how we model it.

How it works

Review & order process

1

Share your reference

Photos, measurements, or a sketch — whatever you have.

2

Scoping call

A short consultation to confirm what's needed and quote the modeling work.

3

We model it

An engineer builds the CAD file, checking fit and function as they go.

4

Review & receive files

You review the model; once approved, you get the CAD/STL files — or send it straight to print.

Questions

Good to know before you upload.

I only have a photo of the part, not the part itself — can you still help?

Often, yes, especially with a few angles and a scale reference in frame. For tighter tolerances, having the physical part (or precise measurements) helps a lot.

Do I own the resulting CAD file?

Yes — it's modeled for you and is yours to keep, print, or manufacture elsewhere.

Can you print it once it's modeled?

Yes — once the model's approved, it can go straight into the same upload → engineering review → quote flow as any other print.
