CAD

Question 1

What is CAD?

Answer 1

> CAD -> Computer-aided design
Way to digitally create 2D drawings and 3D models of real-world products before manufacturing. With 3D CAD, you can share,review,simulate and modify designs.

Question 2

What are the three types of modelling in CAD?

Answer 2

> Solid modelling: works with 3D shapes. Shapes may vary but act together like building blocks.
Wireframe modelling: can help in cases where the surface is complex and curved.
Surface modelling: Highly professional applications demand smooth surfaces and seamless inegration and more complexity.

Question 3

Isometric and Orthographic are types of Drafting method. Explain what each of them represent.

Answer 3

Isometric: a method of representing 3D objects on a flat surface by means of drawing that shows three planes of object. (Shows from 3 perpspectives in single drawing)

Orthographic: a method for representing a 3D object by means of several views from various (2D) planes.

Question 4

How to apply Extrude?

Answer 4

Extrude extends a sketch profile into 3D space to create a solid or cut material.

Question 5

How to apply Revolve?

Answer 5

Revolve rotates a sketch profile around an axis to create a 3D shape.

Question 6

Loft?

Answer 6

Creates a shape by transitioning between multiple profiles.

Question 7

Sweep

Answer 7

Creates a solid or surface by moving a profile along a path.

Question 8

Shell?

Answer 8

Hollows out a solid body, leaving a specified wall thickness.

Question 9

Fillet?

Answer 9

Adds rounded edges to one or more edges of a 3D body or an arc between two lines in a sketch.

Question 10

Chamfer?

Answer 10

Creates a beveled edge between two faces or along an edge.

Question 11

Mirror?

Answer 11

Duplicates features, bodies or components across a plane or line

Question 12

pattern?(rectangular, circular, pattern on path)

Answer 12

Duplicates features or bodies in specified pattern

Question 13

Offset:

Answer 13

creates a copy of a sketch curve at specified distance

Question 14

move/copy:

Answer 14

moves or copies bodies, components or sketches

Question 15

scale

Answer 15

changes the size of body or component

Question 16

combine

Answer 16

joins, cuts, or intersects solid bodies

Question 17

split body/face

Answer 17

divides a body or face using plane or sketch

Question 18

draft

Answer 18

applies a taper to faces of solid body

Question 19

hole

Answer 19

creates holes with customizable parameters (eg counterbore, countersink)

Question 20

thread

Answer 20

adds helical threads to cylinderical faces

Question 21

rib

Answer 21

creates thin support features from open sketch profiles

Question 22

boundary fill

Answer 22

creates or removes volumes using bounding volumes formed by tool selections

Question 23

section analysis

Answer 23

creates cross-sectional view of model for inspection

Question 24

offset plane

Answer 24

creates construction plane at specified distance from a model.
