Our Engineering Support Services

We provide the critical engineering resources you need to prepare your project for manufacturing.

3D CAD Modeling

High-quality parametric models built for production.
We create native 3D CAD files in SolidWorks, Fusion 360, Creo, or the platform of your choice — structured for revision control, downstream tooling, and mechanical performance. Whether it's a single part, a complex assembly, or a fully constrained mechanical system, our engineers model with care and intent.

Use cases:

  • Converting sketches or 2D drawings into full 3D models

  • Building clean assemblies with motion constraints and BOM structure

  • Adapting models to specific manufacturing processes (e.g., draft for molding, corner radii for CNC)

2D Drawing Creation & GD&T Support

Communicate critical tolerances and specs clearly.
We create manufacturing-ready 2D drawings from your 3D models, including tolerances, surface finishes, hole callouts, threads, and GD&T where needed. These drawings are essential for quoting, inspection, and compliance — and we build them to match industry standards.

Includes:

  • Proper title blocks, revision control, and tolerancing schemes

  • Exploded views, section cuts, and detailed callouts

  • Fit, form, and function-driven drawing structure for parts and assemblies

Reverse Engineering & Legacy File Conversion

No CAD? No problem.
If you have a physical part, an old PDF, or an outdated CAD file format, we’ll recreate it with modern, editable geometry — ready for rework, production, or supplier handoff. We also adapt existing models to meet current production needs, including redesigning for new materials or processes.

Common reverse engineering workflows:

  • 3D scan to CAD conversion

  • Manual dimensioning with calipers or CMM

  • Surface reconstruction and clean-up

  • Legacy file updates and reformatting (STEP, IGES, Parasolid, native CAD)

THE ENGINEERING BRIDGE

Have an Idea, But Not a CAD File?

You've got a groundbreaking concept, a napkin sketch, or even a physical prototype, but you need a professional, production-ready 3D CAD model to move forward. This is where many great ideas get stuck.

Our engineering support services are designed to be your technical co-founder. We work with you to translate your concepts into precise, detailed, and manufacturable 3D models and 2D drawings, setting your project up for success from the very beginning.

Engineering & Design Consulting

Get a second set of expert eyes on your concept.
Beyond modeling, our engineers provide input on part geometry, assembly strategy, material selection, and production methods. We plug in as an extension of your team — helping troubleshoot design challenges, reduce cost, and ensure readiness for prototyping or mass production.

Includes:

  • Manufacturability assessments (paired with DFM)

  • Assembly optimization (snap fits, press fits, fasteners, etc.)

  • Material substitution based on use case

  • Tolerance balancing for performance vs. cost

Who We Support

 

    We serve design engineers, sourcing leads, and product developers across industries:

    • Startups who need full design support from concept to launch

    • Mid-sized OEMs with in-house design teams who need overflow capacity

    • Contract manufacturers looking to quote or revise customer-provided files

    • Sourcing teams inheriting incomplete or outdated CAD from legacy vendors

    • Inventors with a sketch or prototype that needs to go digital

How Our CAD Modeling Process Works

Kickoff → Sketch, reference part, CAD file, or notes → Engineering review + project scope

Modeling → Functional requirements & design intent → Fully parametric 3D CAD file (STEP + native)

Drawing Creation → Tolerances, fit types, finishes → Production-ready 2D drawings (PDF + DWG)
Review & Revisions → Your feedback or updated specs → Updated models and documentation
Manufacturing Handoff → Final BOM and production method → Files structured for prototyping or mass production

Why Trustbridge for CAD Modeling & Engineering Support?

Engineers, Not Just Designers: We think beyond CAD aesthetics — we model for manufacturability, cost, and performance.
Process-Aware Modeling: Every part is created with your intended manufacturing process in mind.
Tight Feedback Loops: We work collaboratively and iteratively to ensure designs match your vision and your constraints.
Cross-Platform Capability: From SolidWorks to Fusion, Creo to Inventor — we work in your system or export to any major format.
Seamless Manufacturing Integration: Once your part is modeled, we can quote, prototype, and produce it through our supplier network.
