Models can be reworked and modified easily to aid product development, regeneration and continuous improvement processes in industry. ADVANTAGES More accurate than traditional hand drawn drawings. Drawings can be automatically scaled and re-scaled as necessary. Can be used directly to generate cutting data for CNC machines Models can be stored and retrieved easily. Engineers, designers and technicians can share the design data in computerised manufacturing management systems. Accurate 3D models can be visualised and tested before making in costly materials. Assembly of the final model allows the designer to check for exact fit of the parts.ģ The advantages of CAD Lessens the need for large numbers of expensive draftsman in the designing of a product. 3D models can be viewed from any angle allowing complete visual testing. Each part can be modified at any time and changes will be applied to the final model also. 3-dimensional CAD allows all of the parts of a design to be modelled in separate files and then assembled together into a final model. Designs can be tested virtually before being made from costly materials.

Using 3-dimensional CAD software designers can create fully rendered 3D models of parts and whole assemblies for designs.

It can also be used to develop and firm up design ideas by concentrating on single views and using the range of geometric tools available. 2 What is CAD? : Computer Aided Design 2 and 3 Dimensional CAD: Using 2-dimensional CAD software, designers can create accurate, scaled drawings of parts and assemblies for designs.
