List and describe three basic Boolean operations commonly us

List and describe three basic Boolean operations commonly used in computer geometric modeling software? What is a primitive solid? What does CSG stand for? Which Boolean operation keeps only the volume common to the two solid objects? What is the main difference between a CUT feature and a HOLE feature in Autodesk Inventor? Create the following 2D Sketch and measure the associated area and perimeter. Using the CSG concepts, create Binary Tree sketches showing the steps you plan to use to create the two models shown on the next page:

Solution

anwers

1. JOIN,

CUT &

INTERSECT

2. The primitive solid is a building block that we use to work in 3D.

3. CSG stands for constructive solid geometry, a technique used in solid modelling.

4. Intersect Operation keeps the volume common to the both solids
