Make Your Product Fit, Function, and Last With CAD & Mechanical Engineering

A promising product idea can fail because the enclosure overheats, parts do not align, or the first prototype cannot be assembled. Turn that concept into practical 3D CAD models and mechanical designs built around real dimensions, materials, assembly requirements, and user needs.

Mechanical Product Design

Will your concept still work when it becomes a real object?

Great-looking renderings are not the same as buildable products. SDI helps translate sketches, industrial-design concepts, and rough models into parametric CAD assemblies with attention to fit, clearances, mounting, sealing, service access, and component placement.

We can plan enclosures around boards, sensors, batteries, connectors, fasteners, and the human experience—not discover their conflicts after parts arrive.

Basic 3D prototypes start at $200; advanced CAD and mechanical engineering are scoped separately.

Engineering for Real-World Constraints

How do you catch mechanical problems before expensive rework?

Depending on the product, the engineering workflow may use SolidWorks, Autodesk Fusion, or Onshape for parametric design; STEP files for handoffs; drawings with GD&T; and tolerance-stack analysis. Finite-element or thermal analysis may be appropriate when structural loads or heat make them necessary.

Materials, manufacturing methods, assembly sequences, and maintenance access are considered early, so the model supports the next prototype—not only a presentation.

From Idea to Engineering Detail

What does mechanical CAD design actually deliver?

Design around the details that decide whether a physical product feels finished and can be built.

3D Models & Assemblies

CHECK THE FIT

Create editable part and assembly models around real hardware dimensions, internal packaging, and user-facing geometry.

Enclosures & Mounts

PROTECT THE PRODUCT

Design practical housings, fastener locations, cable paths, brackets, and mounting features for the operating environment.

Drawings & Handoffs

MOVE TOWARD BUILD

Prepare dimensional drawings, interface details, and neutral CAD exports for prototyping and manufacturing review.

Iterative Mechanical Engineering

What happens after the first CAD model looks right?

SDI can review the assembly with electronics and firmware requirements, evaluate manufacturability, create prototype-ready revisions, and incorporate measured feedback from physical builds. When a sensor needs a clear optical path, a battery needs more space, or vibration affects a mount, the mechanical design should respond.

You receive a clearer path from concept to prototype, with revision-controlled design files that can evolve as the product matures.
