Description
This subject is designed to build on the knowledge and proficiency in the principles and techniques of reverse engineering learnt in the Introduction to Reverse Engineering subject, whilst using 3D scanning methods. Through this subject, students gain experience in using 3D scanning technology to capture a component’s complete geometry and using mesh clean-up tools to prepare faceted bodies for downstream modelling and/or manufacturing. They also learn how to identify logical facet shapes and group triangles for use in the creation of faces, use reverse engineering software to create native surfaces on top of imported data, and use deviation analysis to ensure accuracy between the re-engineered part and its original. This subject equips students with the skills necessary to apply reverse engineering techniques using 3D scanning methods for manufacturing, quality assurance, or other purposes.
Subject learning objectives (SLOs)
Upon successful completion of this subject students should be able to:
| 1. | Use 3D scanning technology to capture a component’s complete geometry. (D.1) |
|---|---|
| 2. | Demonstrate knowledge in using point cloud and mesh clean-up tools to remove errors and prepare faceted bodies for downstream modelling and/or manufacturing. (D.1) |
| 3. | Create surfaces on top of imported data to enable use in CAD software. (D.1) |
Course intended learning outcomes (CILOs)
This subject also contributes specifically to the development of the following Course Intended Learning Outcomes (CILOs):
- Technically Proficient: FEIT graduates apply theoretical, conceptual, software and physical tools and advanced discipline knowledge to research, evaluate and predict future performance of systems characterised by complexity. (D.1)
Teaching and learning strategies
The subject uses a combination of self-paced online content, interactive live sessions and industry relevant examples, activities and assessment.
The online component focuses on learning the technical concepts that underpin 3D scanning, capturing an object geometry data and downstream processing of the data that enables recreating the object in computer-aided design software.
Concepts are presented using high-quality videos and interactive text and practice activities. Learners will build a broad introductory understanding of 3D scanning the underlying concepts and relevance for adoption in industry. Each module contains practice activities to engage the concepts within the module. Discussions will be held using online discussion boards and during drop-in sessions.
The interactive live sessions will build on the modules through the practical application of 3D scanning an industrial part of moderate complex geometry. Learners will be able to gain hands-on experience on 3D scanning using scanners used in the industry. Peer learning is part of the live sessions where students can exchange knowledge and experiences.
The assessments focus on 3D scanning pipeline requiring learners to implement this understanding and reflect on how these concepts can be applied to their own professional industry contexts.
