Parametric CAD & Adv Surf Mod
Run by School of Education and Human Development
20 Credits or 10 ECTS Credits
Organiser: Mr Aled Williams
Overall aims and purpose
The aim of the module is to develop and validate students’ practical capability in CAD to a commercial / professional standard. CAD applications enable designers and engineers to rapid and efficiently design and manufacture new products without the need for traditional lengthy prototyping and testing. Skilful implementation of this technology is essential in quickly bringing new innovations market. The module initially focuses on parametric solid modelling of products and their constituent parts. The module progresses onto advanced surface modelling techniques which are highly regarded and sought after within industry. The module also aims to develop students’ ability to generate commercial quality 3D renders and engineering drawings. The module prepares students for SolidWorks CSWA, CSWP and CSWPA – Surfacing certification.

60 -69%: Knowledge base covers all essential aspects of subject matter dealt with in the assignment and shows good evidence of drawing skill beyond this. Conceptual understanding is good. CAD modelling work is constructed in a reliable and efficient manner, with a good appreciation of commercial standards and requirements. Problems of a familiar and unfamiliar nature are solved in a logical manner; solutions are generally correct and acceptable. Performance in transferable skills is sound and shows no significant deficiencies.
70% and above: Knowledge base is extensive and extends well beyond the work covered in the assignment; conceptual understanding is outstanding. CAD modelling work is exemplary and shows a thorough analysis and appraisal of outcomes, with appropriate suggestions for improvement. Problems of a familiar and unfamiliar nature are solved with efficiency and accuracy; problem-solving procedures are adjusted to the nature of the problem. Performance in transferable skills is generally very good.

Resource implications for students
A laptop of PC suitable for running CAD software – see following spec. • Ensuring the amount of RAM in the machine is sufficient for the typical size of datasets is important. Running regular, data-heavy Simulations increases the need for RAM, because large amounts of data typically needs to be loaded during calculations. Minimum amount of RAM: 16GB. If running Simulations, 32GB is recommend. • Graphics: SOLIDWORKS requires a professional, fully-certified graphics card which runs the OpenGL engine in order to function correctly (e.g. Nvidia Quadro and the AMD FirePro). SOLIDWORKS has been known to run on “gaming” graphics cards which use DirectX (e.g. AMD Radeon and the Nvidia Geforce cards), however users may experience graphical glitches. • Processor: CAD is predominantly a single core application. It is more effective to buy faster processors with fewer cores. Some processes in CAD do use multiple cores, e.g. opening and rebuilding drawings with multiple views. Rendering also uses multiple cores and will run effectively with eight or twelve. Simulations run efficiently with two or four cores. Recommendation: Intel i7 or Xeon processors • Storage: A fast mechanical HDD (spinning at 7200RPM or above), or a Solid-State Drive (SSD)
