| Description: | To build the student’s knowledge of computer based engineering communication. This subject aims to build on the basic skills in orthographic drawing achieved in Engineering Graphics and Communications 1 and will enable the student to communicate component part information in a technical situation. The student will able to create three dimensional CAD models, interrogate a model history tree and subsequently generate two dimensional drawing layouts with geometric dimensions. The module exercises will build the students spatial awareness. |

| Learning Outcomes: |
|---|
| On successful completion of this module the learner will be able to | - State the steps required to create a basic 3D solid model
- Identify component features of a 3D model
- Identify and create suitable profile defintions for modelling features
- Apply geometric and dimensional constraints to a sketch profile
- Select an appropriate base feature for initiating a component model
- Combine modelling features to represent a component
- Produce a three dimensional (3D) CAD model
- Create moderately complex solid models by combining modelling features
- Produce 2D drawings sheets directly from a solid model
- Produce orthographic drawings including toleranced dimensions, enlarged details, auxiliary views, threaded detail
- Demonstrate three dimensional spatial awareness by orienting /positioning component features on a three dimensional model
- Print drawings with standard title blocks and multiple views correctly scaled
