D. 5
Please scroll down to see the correct answer and solution guide.
Right Answer is: C
SOLUTION
Explanation:
The four categories are
1) Geometric modelling: Geometric modeling is as important to CAD as governing equilibrium equations to classical engineering fields as mechanics and thermal fluids.
Basic Geometric Modeling Techniques
- 2-D Projection (Drawings)
- Wireframe Modeling
- Surface Modeling
- Analytical Surface
- Free-form, Curved, & Sculptured Surface
- Solid Modeling
- Constructive Solid Geometry (CSG)
- Boundary Representation (B-Rep)
- Feature Based Modeling
- Parametric Modeling
2) Engineering analysis: It is the broad usage of computer software to aid in engineering analysis tasks. It includes finite element analysis (FEA), computational fluid dynamics (CFD), multibody dynamics (MBD), durability and optimization. It is included with computer-aided design (CAD) and computer-aided manufacturing (CAM) in the collective abbreviation "CAx".
3) Design review: It acts as a publisher, merging files from many sources - such as raster images, word processing documents, spreadsheets and drawings from other CAD packages - into a single, multipage document.
4) Evaluation and automated drafting: Evaluation is checking whether the designed part has been designed properly or not and if they will fail in practical situations. It is very important part of the whole design process. With CAD software the process of design review and evaluation has become much faster and convenient.
