MEGR 3231 Final Exam Questions
with complete solution 2025
What is CAD?
What are two types of CAD? - correct answer ✔Computer Aided Design
The implementation of computers in the creation. modification, analysis, and
optimization of a design.
Drafting and Modeling
What is CAM?
What are 3 types of CAM? - correct answer ✔Computer Aided
Manufacturing
Application of computers to the creation and assembly of physical
components.
NC - "Numerical control" of computer driven machine tools.
RP/AM - Rapid Prototyping / Additive Manufacture
CAPP - Computer Aided Process Planning
What is CAE?
,What are 3 types of CAE? - correct answer ✔Computer Aided Engineering
FEA - Finite Element Analysis. Can be mechanical of thermal. The
mechanical analysis can be static or dynamic.
CFD - Computational Fluid Dynamics
Simulations.
CAD Research in the 50's - correct answer ✔CNC Programming
CAD Research in the 60's - correct answer ✔Sketchpad [Ivan Sutherland]
Describe Sketchpad {Ivan Sutherland] - correct answer ✔Object oriented
programming
Computer power was finally available
2D sketches
Horizontal and vertical line, arcs, zoom capability
More of computer aided drawing and drafting
CAD Research in the 70's - correct answer ✔Corporate Development
,Computer Power Advances
(Super computers are room sized)
What were some CAD software companies in the 70's - correct answer ✔-
Unigraphics
-AutoTrol
-CATIA
-Computervision > Sun > Prime
CAD Research in the 80's - correct answer ✔Software Companies
What were some CAD software companies in the 80's - correct answer
✔Autodesk
Bentley
Dassault
Parametric Technology
What are the forms of 2D CAD? - correct answer ✔Raster
Vector
What are the forms of 3D CAD? - correct answer ✔Surface
Solid
Wireframe
What is raster?
, 1 bit and 3 bit - correct answer ✔A field of points that can be turned on and
off with different colors. The whole field presents a complete graphic. Think of
it like an image. (bitmap)
Depth of color depends on memory in bits per pixel.
1 bit (Monochrome)
Black or White, 1 on-off switch
3bit (Primaries)
Each pixel has 3 on-off switches
**SCALING CAUSES DISTORTION**
What is vector? - correct answer ✔A set of simple geometric features with
mathematical features.
Can be scaled without distortion
Describe Electronic Engineering Drawings - correct answer ✔Allows for
easier drawing modification and duplication.
Simplifies the transfer of data
Reduce paper use [Not really though]
