Mangesh L.

I'm a Mechanical Design Engineer with 4+ years of corporate experience in product development at a global manufacturing organization, working in engineering design, cross-functional technical coordination, and quality-focused CAD review. I specialize in PTC Creo Parametric and bring hands-on production-environment judgment to every engagement — whether that's building a model from scratch or reviewing someone else's design before it goes to manufacturing.
What I offer:
CAD Design Review & QC — thorough review of 3D models and 2D drawings for accuracy, completeness, and manufacturing readiness
DFM (Design for Manufacturability) Audits — identifying tolerance issues, material/process mismatches, and assembly feasibility problems before they become costly manufacturing errors
GD&T Review & Tolerance Stack-up Verification — ensuring dimensioning and tolerancing is correct, complete, and manufacturable
3D Parametric Modeling & 2D Drafting (Creo) — parts, assemblies, sheet metal
Reverse Engineering — physical part/reference to CAD model
File Format Conversion (STEP, IGES, STL, DXF)
BOM creation and drawing package assembly
Why work with me:
4+ years hands-on corporate CAD and product development experience — real manufacturing judgment, not just software operation
Strong at catching errors others miss — tolerance conflicts, incomplete dimensioning, non-manufacturable features
Every engagement is scoped precisely upfront and delivered against a clear technical standard — no surprises
Comfortable working independently or reviewing output from your existing design team/vendors
Whether you need a design built or an existing design checked before it goes to production, send me your requirements and I'll confirm scope and timeline before we start.
