From Sketch to
Manufacturable Part.

I turn rough sketches, concepts, and CAD that isn't quite production-ready into supplier-quotable manufacturing packages: SolidWorks models, dimensioned drawings, flat pattern DXFs, BOMs. Licensed P.Eng, 8+ years in production-focused mechanical design.

The moment founders call me

Where projects go wrong
before a supplier ever sees the file.

🔍
Your CAD isn't quote-ready

A model that "works" on screen isn't the same as one a supplier can actually price. Undefined tolerances and missing callouts turn into delays and re-quotes.

📐
Your drawings raise more questions than they answer

If a supplier comes back asking what you meant instead of giving you a number, that's time and money lost before production even starts.

⚠️
DFM issues surface after tooling, not before

Wall thickness, draft angles, material selection — catch these in review, not after the mold is already cut.

How I work

From sketch to supplier-ready package

Four steps. Defined outputs at every stage. Nothing left vague.

1
Send the File
Sketch, concept, or existing CAD, whatever stage it's at. I look at what's actually there.
2
DFM Review
I flag manufacturability issues before they become expensive: tolerances, wall thickness, draft angles, process fit.
3
Build the Package
Full SolidWorks CAD, dimensioned drawings with GD&T, flat pattern DXFs, BOMs.
4
Supplier-Ready Handoff
STEP, DXF, PDF, the questions a vendor would ask are already answered.

What you get

Sketch to CAD to supplier-ready package

🔧
Sketch to CAD

Rough concepts and hand sketches turned into production-ready SolidWorks models.

📏
DFM Review

Sheet metal, CNC, injection molding, checked before tooling or fabrication is committed.

📄
Fabrication-Ready Drawings

Dimensioned, GD&T per ASME Y14.5, ready for a shop to work from without interpretation.

📦
Supplier Quoting Packages

STEP, DXF, BOM, formatted the way a vendor actually needs it.

🏭
Injection Mold & Overmolding Tooling

Tooling design experience from real automotive production parts.

🤝
Full-Package Delivery

Not a model handed back with no path forward — a complete package from sketch to supplier handoff.

"Engineering becomes enormously valuable once founders like me realize what you've missed. The amount of spilled milk I could have avoided is huge."

About

Moataz Ibrahim, P.Eng

I'm a licensed Professional Engineer with 8+ years in production-focused mechanical design: two years on Michelin North America's CA1 plant engineering team, four years at Protocase programming laser cutters and press brakes, running CMM inspection, and delivering custom enclosures and fabricated parts, and injection mold and overmolding tooling design at Neocon International for automotive production parts.

I know what a shop actually needs from a file because I used to run the machines that file lands on. Now I take that same eye and apply it to your part: sketch to CAD, DFM review, fabrication-ready drawings, supplier quoting packages.

Send me a sketch, a concept, or a CAD file that isn't quite production-ready — I'll tell you what it needs.

Before you commit the next dollar

Have a sketch or a part that needs to be production-ready?

Send it over. I'll tell you what it needs to become a package a supplier can actually quote.
