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.
Catch fit and clash issues on screen, not on the shop floor.
Move from concept to build-ready files sooner.
Parts designed for the process need less rework.
Engineers, suppliers and shops work from the same model.
Parametric models update when a dimension changes.
Add design capacity without hiring.
Accurate solid models of machined, molded and fabricated parts.
Multi-part assemblies with mates, clearance checks and parts lists.
Dimensioned drawings with tolerances for the shop.
Bent, cut and welded parts and frames.
Turn paper, PDF or DWG drawings into editable 3D models.
Review tolerances, wall thickness and assembly for CNC, molding and fabrication.
Modify existing CAD files and drawings.
Models and drawings your supplier can use directly.
Problems found before manufacturing.
Clear files shorten the build start.
Fewer revisions and fewer remakes.
Defined tolerances and fits.

Full part models with features and tolerances.
Assemble, check fit and create drawings.
Editing, effects as needed.
You give feedback and we refine.
Delivered in your formats, on time.
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.
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.
