2D And 3D CAD Design

Intratech are proud to host a team of expert CATIA engineers with advanced skills in 3D CAD modelling. 3D CAD is the backbone of the engineering design process – It enables the creation of design concepts and forms the basis of information to support manufacture. It also facilitates communication and the exchange of ideas across a multi-disciplined team and is the key element of product development. CAD data is used to enable a range of support activities including CNC Manufacture, Photorealistic Rendering, Digital Mock-up, Assembly Simulation and Ergonomic Assessment – All of which, Intratech can offer as a service.

The foundation of 3D CAD design begins at the sketch phase of 3D part design, from which sketch-based features are created. Expert CAD part design within CATIA is exercised by using functions, laws, relations and parameters which increase the efficiency of CAD design by linking sketch-based features within the CAD part model and ultimately reducing the yield time for complex CAD part design. Advanced CAD assembly design skills allow our engineers to produce complex assemblies efficiently by leveraging advanced techniques within CATIA.


The completion of CAD design is presented through the creation of engineering drawings. The team of expert engineers at Intratech are proud to be certified in Geometric Dimensioning & Tolerancing (ASME Y14.5-2009 International Drawing Standard; SANS 10111 South African National Standard; BS 8888 and ISO International Drawing Standard) ensuring all engineering drawings are precisely annotated with the required tolerances, geometrical characteristics, datums and modifiers.

Our team of experts at Intratech will provide a consolidated CAD design solution from design requirements, to CAD part and assembly modelling and concluded with the complete engineering drawings to spec, in accordance with Geometric Dimensioning & Tolerancing annotations.
