Mechanical CAD Design Services

Professional Mechanical CAD Design Services Built for Manufacturing Every good mechanical product starts with clear, accurate CAD. NBY IT Solution is a mechanical CAD design company with 90+ 3D artists, 17+ years of experience and 224,000+ 3D models created. We turn your ideas, sketches and samples into 3D models, assemblies and drawings that your engineers, machinists and suppliers can build from.

What Is Mechanical CAD Design? Mechanical CAD design is the process of creating precise 3D models and 2D drawings of mechanical parts and assemblies using CAD software. It covers part geometry, how parts fit together, tolerances, materials and the drawings a shop needs to make them. A well-built model lets you check fit, clearance and manufacturability on screen before any metal is cut or any prototype is printed.

WHY BUSINESSES NEED IT

Frequently Asked Questions About Mechanical CAD Design Services

Don’t see what you’re looking for?
What do you need to start a mechanical CAD project?

Sketches, photos, PDFs or existing CAD files, plus key dimensions and units, material, how the part will be made (CNC, molding, sheet metal, 3D printing) and the file formats you need.

Yes. We can model from sketches, photos or samples. The more dimensions you share, the more accurate the model. For parts that must be rebuilt from a physical sample, see our reverse engineering services.

Formats such as STEP, IGES, STL, native CAD files and PDF, DWG or DXF drawings, as agreed.

We work mainly in SolidWorks and can deliver neutral formats for other CAD systems. 

Yes, with dimensions and tolerances for your shop or supplier.

Yes. We can rebuild paper, PDF or DWG drawings as editable 3D models.

Yes. Send the files and tell us what needs to change.

It depends on part count and complexity. We confirm the timeline in your quote.

We provide the CAD design and drawings. Your manufacturer builds the parts. 

We can sign an NDA before work starts.
