Engineering services for every stage of product development
Engage GoBigCAD for a single deliverable or the full path from concept to manufacturing-ready files.
Product Development
End-to-end product development: concept exploration, mechanical design, engineering validation, DFM review and production-ready documentation in one continuous engagement.
Learn more →3D CAD Design
Parametric mechanical CAD design built around real design intent — clean feature trees, correct constraints and models that are actually editable, not just visually correct.
Learn more →Mechanical Engineering
Mechanical engineering support for product teams: material and process selection, tolerance analysis, structural sanity-checking, and resolving specific technical problems in an existing design.
Learn more →Design for Manufacturing (DFM)
A DFM pass evaluates your design against the realities of your chosen manufacturing process — wall thickness, draft, undercuts, tolerances, tooling complexity — and returns specific, prioritized changes.
Learn more →Prototyping Support
CAD prepared specifically for prototyping — correct orientation, tolerances and file health for 3D printing or CNC — with guidance on which method fits your stage of development.
Learn more →Engineering Drawings
Clear, correctly toleranced 2D manufacturing drawings with proper GD&T, so quotes are accurate and incoming parts can be inspected against a real standard.
Learn more →Injection Molding Design
Part design for injection molding: consistent wall thickness, appropriate draft, rib and boss design, and gating/parting-line-aware geometry that reduces tooling cost and cycle-time risk.
Learn more →CNC Design
Part design and review for CNC machining: setup-aware geometry, achievable tolerances, and features that avoid unnecessary machining time or tooling access problems.
Learn more →Reverse Engineering
Reconstructing parametric CAD from physical parts, legacy drawings, or 3D scan data — for parts that need to be modified, replaced, or manufactured again with no original digital source.
