The module introduces the learner to the principles of computer aided design and engineering drawings using standard drawing practices. It equips the learner with a range of knowledge and techniques necessary to create standardised 3D models and 2D drawings for product design projects, using industry-standard solid modelling software.
Parametric CAD / Virtual Modelling:
Basic principles of ‘surface modelling’ vs ‘solid modelling’, ‘direct modelling’ vs ‘parametric modelling’, part/component creation, assembly creation, drawing production and file management (file naming, folder usage)
2D Profile Techniques:
- Planes, Geometry, Relationships
- Dimensioning
- Sketch conversion, Offset and mirror
- Sketch filleting and chamfering
- Sketch editing and copying deleting
Part Modelling Techniques:
- Feature based modelling
- Material addition and removal features (‘extrusion’, ‘revolve’, ‘fillet’ and ‘chamfer’, hole)
- ‘Thin’ ‘shell’ features
- Linked, associative features (‘mirror’ and ‘pattern’)
- Feature editing and modification
Assembly Techniques:
- Creation of assemblies via linked parts/components
- Insertion of parts/components, part copies & deletion
- Assembly mates, mate conflicts and offsets
Drawing Creation:
- Drawing Sheet setup (title block data, text/font styling, lineweight and colour)
- Insertion of Drawing Views (principal, model, auxiliary, detail, section)
- View scaling
- Dimensioning
- Drawing Annotation
Data Exchange
- Reasons for generation of separate manufacturing-specific data
- Comparison of industry-standard filetypes
- Data export methods
