What this service covers
New product design
Concept development through detailed design: packaging studies, material selection, design-for-manufacture and design-for-assembly reviews, and release-quality drawings — taken from a napkin sketch or a requirements spec to a manufacturable product.
Sustaining engineering, drafting & 3D modelling
Engineering change management, drawing updates, BOM maintenance and production support for products already in the field — the steady, high-volume work that keeps manufacturing lines and service organisations moving.
FEA simulation & GD&T validation
Structural, thermal and fatigue analysis in ANSYS to validate designs before tooling commitments, and GD&T application and validation to ASME Y14.5 — tolerance stacks that hold up on the shop floor, not just in the model.
Reverse engineering
Scan-to-CAD reconstruction of legacy parts with no surviving drawings: point-cloud processing, parametric remodelling, and re-established design intent with documented assumptions — essential for obsolescence and long-life fleet support.
Class A surface building
Production-quality Class A surfacing for visible automotive and industrial-design geometry — curvature-continuous surfaces built in CATIA to styling intent, validated with highlight and reflection analysis.
CAD legacy migration
Structured migration programmes from 2D drawing archives to full 3D parametric models — batch conversion with modelling standards, checking gates and traceability, so the migrated library is usable engineering data rather than geometry dumps.
How a mechanical engagement runs
The numbering below maps to actual engagement stages — each stage has an entry criterion, a deliverable and a decision point.
- Stage 01
Scope & standards alignment
We align on your CAD environment, drawing standards, checking rules and release process before any production work — the discipline that makes offshore delivery indistinguishable from your own team's output.
- Stage 02
Pilot work package
A bounded first package — a part family, a drawing backlog tranche, one FEA study — delivered end to end to calibrate quality expectations and cycle times on both sides.
- Stage 03
Ramp-up, onsite and offshore
Team scales against an agreed capacity plan: onsite engineers at your facility where daily interaction with design owners matters, offshore pods in Bengaluru for volume work — one workflow, one quality system.
- Stage 04
Steady-state delivery under quality gates
Work packages flow through defined checking and release gates with measured first-time-right rates and turnaround times reported monthly — engineering throughput you can plan production around.
- Stage 05
Sustaining ownership
Long-run arrangements where Crest owns a product family's sustaining engineering — changes, drawings, supplier queries — freeing your senior engineers for new development.
What you walk away with
- Release-quality CAD, drawings and analysis in your environment, to your standards
- Validated designs — FEA reports and GD&T stacks that survive tooling and production
- A migrated, usable 3D parametric library where there were 2D archives
- Measured throughput: first-time-right rates and turnaround times you can plan against
