3D CAD Modeling Mechanical Product Design and Manufacturing Drawing

Turn your concept, sketch, reference image, or existing part into a detailed 3D CAD model and a clear engineering drawing package.

I’m Malik Mubashar Riaz, a Mechanical Design Engineer with experience in product development, mechanical assemblies, reverse engineering, and design for manufacturing. I use SolidWorks, Autodesk Fusion 360, and Creo to develop practical designs suited to your project requirements.

Services include:

- Parametric 3D modeling of mechanical parts and assemblies
- Product design and refinement
- CAD reconstruction from sketches, photographs, or supplied measurements
- Reverse engineering from scan or mesh data, depending on source quality
- Sheet metal components, frames, and weldments
- Enclosures, housings, brackets, and mechanical mechanisms
- Assembly fit, clearance, and interference checks
- 2D manufacturing drawings with dimensions, tolerances, and relevant fabrication details
- Exploded views, assembly drawings, and bills of materials
- STL preparation for 3D printing and product renders for presentation

What you receive

Depending on the agreed scope, deliverables can include editable native CAD files, STEP files, STL files, PDF drawings, DXF files, assembly documentation, and rendered images.

Models are structured for future revisions, with key dimensions and features kept editable. Material selection, manufacturing processes, assembly requirements, and functional clearances guide the design.

What I need to get started

Share your sketches, reference images, dimensions, intended function, preferred materials, and manufacturing process. If some dimensions are missing, I can develop an initial model using agreed engineering assumptions and refine it with your feedback.

Whether you need a single component or a complete mechanical assembly, I can help you develop a clear, practical design package for prototyping and manufacturing.
