Overview

Computer Aided Design has entirely replaced the drawing-board in industry. There are different 'types' of CAD application, including 2D CAD, Parametric CAD (both 2D and 3D), and surface modelling software. The SQA specify that parametric CAD must be used for creating models and drawings. 

There are many options available, from paid platforms such as Solidworks, Catia, Creo, to free-to-education options such as Autodesk Inventor, Autodesk Fusion, and PTC On-Shape. There are also a host of free options available.

Computer Aided Design

Computer Aided Design is a complex topic that takes a significant proportion of the SQA Higher Graphic Communication course. These course notes and resources are designed to help pupils prepare for the exam and ensure they fully understand the terminology and principles of 3D CAD. 

These CAD notes tie with the CAD Challenges shown further below, but can be used independently. The course notes have over 70 questions and tasks to complete.
