About this service

I provide mechanical CAD design and product development support for functional parts, assemblies, fixtures, enclosures, adapters and prototypes.

My services include parametric 3D modelling, 2D-to-3D conversion, reverse engineering from drawings, photographs or measurements, assembly design, design for manufacturing, design for additive manufacturing, technical drawings and print-ready files.

I work primarily with SolidWorks, CATIA V5, Autodesk Inventor and AutoCAD. Deliverables may include native CAD files, STEP, IGES, STL, 3MF, DXF, PDF drawings, exploded views and revision-ready technical documentation.

Each project is reviewed before starting to define the scope, required files, delivery time and included revisions. Package selection depends on geometry, number of components, functional requirements and documentation level.
