Step
Requirement & Reference Study
Fit, function, materials and constraints defined before any geometry is drawn.
Mechanical CAD Services
Mechanical CAD that survives contact with a real factory floor.
Full-cycle mechanical CAD, from a rough concept or sketch through detailed assemblies, mechanism design and the documentation a manufacturer needs to quote and build.
Clear scope, editable files, practical handoff
The service page explains the risk it solves, the deliverables included and the workflow used to reach a production-ready result.
Where this usually goes wrong
A lot of CAD work stops at “it looks right.” Wall thickness that was never checked against the manufacturing process, mechanisms that bind under real load, tolerances copied from a template instead of calculated. Those gaps do not show up until tooling money has already been spent.
What you get
- Concept CAD from sketches, references or a rough prototype
- Mechanism design: latches, hinges, gears, linear actuation
- Full assembly modeling with mates and interference resolution
- Structural and thermal FEA where load, heat or fatigue matter
- Production-ready drawing packages with GD&T and BOMs
- Design iteration through prototype and manufacturer feedback
How it works
A practical five step workflow.
Every stage produces a clear decision, review point or manufacturing deliverable.
Step
Concept CAD & DFM Review
Parametric modeling reviewed early for moldability, machinability and assembly.
Step
Detailed Modeling & Simulation
Full assemblies, tolerancing, and FEA/thermal validation where load or heat matter.
Step
Manufacturing Drawings & GD&T
Dimensioned packages, flat patterns, BOMs and tolerance callouts a supplier can quote.
Step
Prototype & Handoff
Prototypes confirm fit and function, then final files are packaged for production.
Proof, not promises

The portfolio example shows how the same engineering decisions appear in completed work.
Project 14
Bench Grinder Assembly for AI Training Dataset
A configurable cordless screwdriver built around a 7.2:1 planetary gearbox and a coreless 12V, 16,000 RPM DC motor, with Precision, High Torque and Service configurations managed from a single master model rather than three separate files.

Can you start from a rough sketch or a physical prototype instead of a spec sheet?
Yes, that is the normal starting point for most projects. Concept development and resolving what is not yet defined is part of the process, not a blocker to starting.
Do you handle mechanisms as well as static housings?
Yes, latch, hinge, gear and linear actuation mechanisms are regularly part of the scope, not just enclosure geometry.
Will you flag manufacturability issues, or only model what I ask for?
Manufacturability review is built into the modeling process itself. If something will not mold, machine or assemble cleanly, that gets flagged before it is buried in a drawing.
What industries do you typically work in?
Consumer products, wearable electronics, EV hardware, electromechanical tools, industrial actuators and precision instrument enclosures.
How do revisions work after I review the first CAD pass?
Revision rounds are built into the project structure, and clear milestones make it obvious what changed and why between versions.
