Design and detail
3D CAD modelling
Parametric parts and assemblies, set up for what comes next: analysis, drawings or the machine shop.
- You send
- Sketches, a specification, 2D drawings, scan data or an existing model to improve
- You get back
- Native parametric Inventor or SolidWorks models, plus STEP or Parasolid, with 2D drawings, PDFs and exploded views

Overview
Built to be changed
Key dimensions, features and relationships are controlled parametrically, with a clear feature tree and consistent naming, so design changes, variants and manufacturing updates go in quickly and predictably.
Modelled with manufacture in mind
Our engineers understand the materials, processes and tolerances behind each feature, so the model reflects how the part will actually be made, whether that is by machining, fabrication, moulding or printing.
Checked before release
Models and assemblies are checked for dimensional integrity, interference and manufacturability. Drawings follow BS 8888 with ISO geometrical tolerancing (ISO GPS), with surface finishes and parts lists where they are needed.
What we model
- New products and components
- Structural frames and fabrications
- Mechanisms, tooling and jigs
- Industrial equipment and process layouts
- Existing models that need simplifying or improving
One model
Built once, used for everything after
The model we build goes straight into analysis, flow simulation and drawings, without being rebuilt.
Process
How a project runs
- 01
Design inputs
Drawings, sketches, parts or a short specification. Where needed, we agree key parameters, interfaces and performance with your team first.
- 02
Model development
Modelled in Inventor or SolidWorks, with the key dimensions and relationships set up before the detail goes in.
- 03
Verification
Assemblies checked for interference, and each part for how it will be made.
- 04
Delivered
Models issued in the formats you asked for, with assembly documentation and renders where they help.

Questions
Questions we are often asked
How detailed will the model be?
As detailed as the job needs, from a simplified concept model to a fully detailed, production-ready assembly.
Can you model from 2D drawings or scans?
Yes. We build 3D models from 2D drawings, scan data or sketches, and the same engineers handle our paper to CAD and reverse engineering work.
Which CAD software do you use?
Autodesk Inventor and SolidWorks, so you get native parametric models. We also supply STEP or Parasolid, and IGES, DWG or DXF where your system needs them.
Can the models be used for simulation and rendering?
Yes. Our models are structured for direct use in FEA, CFD and photorealistic rendering.

Developing a whole product?
Design to manufacture takes it from specification to production in six stages, with 3D CAD used throughout concept and detail design.
