Turn design intent into production-ready 3D geometry.
Intratech's experienced CATIA engineers help turn concepts, drawings, existing components and legacy CAD data into accurate digital models that can support design development, manufacturing, simulation, visualisation and downstream engineering.
CAD DESIGN
REVERSE ENGINEERING
SURFACING
MANUFACTURING READYWhen engineering capacity or CAD data becomes the bottleneck
A good 3D model is more than a visual representation. It becomes a reusable engineering asset that can connect concept development with detailed design, manufacturing, simulation and documentation..
01
Existing parts without usable CAD
Physical components, legacy products and tooling may need to be reconstructed digitally before they can be modified, analysed, reproduced or integrated into new designs.
02
Complex geometry needs specialist skills
Advanced surfaces, contoured forms, composites and sheet-metal products often need more than basic solid modelling to create robust, editable engineering geometry.
03
Different CAD systems create friction
Customers, suppliers and project teams may work in different CAD environments. Converting and repairing data can prevent unnecessary redesign and lost engineering time.
Intratech 3D modelling capabilities
Our engineering team supports a broad range of modelling tasks, from everyday part and assembly creation through specialist geometry reconstruction and manufacturing-oriented design.

2D & 3D CAD Design
Create and develop parts, assemblies and engineering geometry from sketches, drawings, concepts or existing data. Models can form the basis for manufacturing, digital mock-up and engineering documentation.
Reverse Engineering
Convert existing physical objects or digitised geometry into usable CAD models for redesign, retrofit, digital manufacturing, drawings, CAM and future product development.
Surfacing
Develop advanced and contoured geometry using specialist surface-modelling techniques, with surfaces linked into robust solid models where required.
Composites
Support composite product development for demanding sectors such as aerospace, automotive, marine and industrial applications where lightweight, high-performance structures are required.
Sheet Metal Design
Create sheet-metal parts around manufacturing requirements including bends, cut-outs, formed features and production-ready definitions for fabrication workflows.
CAD Data Conversion
Convert engineering data between proprietary CAD environments and open standards such as STEP and IGES, reducing the need for time-consuming manual recreation.
Engineering data built for what happens next
The value of 3D modelling increases when the geometry can move confidently into downstream engineering. Intratech's modelling services are designed with those later activities in mind.
From concept modelling to manufacturing support, the objective is to create usable engineering geometry—not simply a model that looks correct on screen.

Manufacturing support
Use accurate CAD geometry as the foundation for machining, fabrication, tooling and other production activities.
Digital validation
Support assembly reviews, spatial checks and digital mock-ups before committing time and material to physical builds.
Visual communication
Create a strong digital product definition that can support photorealistic rendering, reviews and communication across multidisciplinary teams.
Reusable design intent
Where appropriate, build associative and parameterised geometry so design changes can be managed more efficiently than with disconnected static models.
A practical route from source data to usable CAD
The exact workflow depends on the project, but the engineering objective stays consistent: understand the requirement, create the correct geometry, validate it and deliver the data in a form that supports the next stage.
1 Define the engineering requirement
We review your source information, required outputs, CAD environment, manufacturing constraints and how the model will be used downstream.
2 Create, convert or reconstruct the geometry
Our engineers build new CAD, convert existing datasets or reconstruct physical components using the modelling approach appropriate to the job.
3 Review model quality and design inten
Geometry, interfaces and model structure are checked against the agreed requirement so issues can be addressed before handover.
4 Deliver for the next engineering activit
Models can be supplied in the agreed native or exchange format and prepared to support drawings, CAM, simulation, digital mock-up or continued design development.
Why outsource 3D modelling to Intratech?
Use specialist engineering capacity when you need it—whether the challenge is workload, missing CAD, specialist modelling capability or the need to turn old data into a useful digital asset.
ENGINEERING CAPACITY
Scale when needed
Add experienced CAD resource to support project peaks, overflow work or specialist tasks without permanently increasing internal headcount.
LEGACY PRODUCTS
Recover digital definition
Turn drawings, physical parts and older geometry into CAD that can support modification, retrofit, reproduction and future development.
COMPLEX GEOMETRY
Specialist capability
Bring advanced surfacing, composites, sheet-metal and reverse-engineering skills into projects that need more than standard solid modelling.
DATA EXCHANGE
Reduce rework
Convert and repair engineering data so customers, suppliers and internal teams can work together across different CAD environments.
DOWNSTREAM USE
Design once, reuse
Create engineering geometry that can support manufacturing, drawings, rendering, mock-up, simulation and other digital processes.
PROJECT DELIVERY
Keep work moving
Remove modelling bottlenecks that delay design reviews, manufacturing preparation or the release of engineering information.
