3D Modelling & Assembly
Precise parametric 3D models of components, sub-assemblies, and full products
Every part modelled to spec — assemblies that fit first time.
What This Service
Actually Covers
Accurate 3D modelling is the foundation of every mechanical design. We build fully parametric, history-based models in SolidWorks, Fusion 360, or STEP format — from individual custom components and PCB enclosures to complete product assemblies. Every model is structured for ease of modification and downstream use in simulation, rendering, and manufacturing.

Model-based definition (MBD) with 3D annotations
How We Approach
This Service
A clear, structured methodology tailored specifically to this engagement.
Requirements & Reference Geometry
Gather all dimensional constraints, PCB outlines, mounting requirements, and aesthetic references.
Initial Modelling & Concept Review
Build initial 3D models and review with stakeholders for fit, form, and function before detailing.
Detail Modelling & Assembly
Add all features, interfaces, and fasteners. Build the full assembly and verify fit with all sub-components.
Export & Handover
Export in all required formats, document model structure, and hand over to downstream teams.
Ideal For
Engineering teams needing precise 3D models for downstream manufacturing, simulation, or rendering.
What You Receive
Native CAD files, STEP/IGES exports, assembly BOM, and model documentation.
