Q

What does the SHELL tool do?

A

Removes material from a feature or object creating a hollow cavity with a specified wall thickness.

17
Q

What does the FILLET tool do?

A

Rounds off one or more edges or faces with a specified radius.

18
Q

What does the CHAMFER tool do?

A

Applies a bevel to one or more component edges.

19
Q

What is a COMPONENT?

A

A component is a part of an assembly

20
Q

What is an ASSEMBLY?

A

An assembly is where multiple components / features are brought together and combined to make one item.

21
Q

What is a SUB-ASSEMBLY?

A

a unit assembled separately but designed to be incorporated with other units into a larger manufactured product.

22
Q

What is a WORKPLANE?

A

A workplane is a location with two out of three axes, X, Y and Z and users can choose to start a new sketch on one.

23
Q

What is an AXIS?

A

An axis

24
Q

What is a FEATURE?

A

A feature is an object in CAD

25
Q

What is a PROFILE?

A

A profile is a closed circuit sketch without depth

26
Q

What is a SKETCH?

A

A sketch is a simple drawing on CAD normally made up of circles and lines.

27
Q

What is a FACE?

A
28
Q

What is an EDGE?

A

An edge is a part of a 3D feature / object found between two faces.

29
Q

What does MATING do when assembling?

A

Constrains two faces to each other so that their directions of movement are limited.

30
Q

What does ALIGNING do when assembling?

A
31
Q

What is a SOLID MODEL?

A

A solid model is

32
Q

What is a WIRE FRAME?

A

A wire frame is a technique for representing 3D objects, in which all surfaces are visibly outlined in lines, including the opposite sides and all internal components that are normally hidden from view.

33
Q

What is TOP DOWN MODELLING?

A

Top down design is an option to create new parts within assembly.
Constraints are the existing geometry elements from other parts within
assembly: lines, planes, surfaces, points, vertices (Vertices - where two or
more straight lines meet for example – corners of a cube).

34
Q

What is BOTTOM UP MODELLING?

A

Bottom up modelling is when parts are modelled then inserted and
fixed in relation to other components in an assembly using mates.

35
Q

What are VERTICES?

A
36
Q

What is a MODELLING TREE / HIERARCHY?

A

The model tree contains a hierarchical list of features or components in the order in which they were created

37
Q

What is a MODELLING PLAN?

A

A modelling plan is

38
Q

What are CAD LIBRARIES?

A

CAD library provides a place for every designer and engineer to easily access, locate, download, save, and share commonly reused CAD data.
