Q

ISOMETRIC PATTERN

A

The pattern is made from equally sized equilateral triangles forcing the drawing into lines at 30°, 90° and 150°.
The sizes of these triangles can be easily changed to suit the drawing.

20
Q

KNURLING

A

A roughening effect, produced on a lathe, on round sections of metal to give a better grip.
Diamond Style which leaves a diamond pattern.
Parallel Style which leaves a series of parallel lines.

21
Q

LAYERS

A

Allows logical drawing separation.
Different elements are drawn on separate levels. Used to isolate parts of a complex drawing - viewing only the parts that are required.

22
Q

LIBRARY

A

Storage of suitable, frequently used clip art items ready for use within particular documents.
Suitably formatted for ease of use in all programs accessing the library.

23
Q

LINE TYPE

A

Style and thickness of line e.g. solid or broken - thick or thin.

24
Q

LOCK TO GRID

A

The cursor is forced to jump to the nearest grid point improving accuracy greatly.

25
Q

MANIPULATE

A

To change the overall shape of a part by different methods of transformation.
To move and adapt a drawing’s position.

26
Q

MIRROR

A

Copies and flips selected drawing part about a specified line.

27
Q

MODELLING

A

Produces a 3D graphic when 2D information is input. Allows the manipulation of the 3D image in real time with the mouse.

28
Q

MOVE

A

To change the position of one part of a drawing to a different position on that same drawing.

29
Q

ORTHOGRAPHIC PATTERN

A

The pattern is made from equally sized squares. The sizes of these squares can be easily changed to suit the drawing.

30
Q

PASTE

A

To transfer a part of a drawing, from the clipboard, to the main page.
Paste process can be repeated as many times as required.

31
Q

PATTERN

A

Used to produce a row or 2D series of copied parts - ‘Duplicated Array’.

32
Q

POLAR REFERENCE

A

Next line in a drawing positioned using measurements always referenced by the length and angle of the required line e.g. (100mm, 60°)

33
Q

PRECISION

A

The accuracy of the dimensioning.
Software will adjust all sizes to suit set precision.

34
Q

REFERENCE

A

An exact position on a drawing sheet from another exact position.

35
Q

REFLECT

A

See ‘Mirror’.

36
Q

RELATIVE REFERENCE

A

Next point in a drawing positioned using measurements always referenced from the previous point in a drawing.

37
Q

REPEAT

A

Copy selection a number of times.
Each copy is moved or rotated a specified amount from the previous copy in the sequence.

38
Q

ROTATE

A

Turn a selected part through a defined angle with respect to a certain point.

39
Q

RUBBER BANDING

A

A light construction line which follows the cursor while drawing to allow for easier alignment.

40
Q

RULER

A

Additional tool which allows the accurate measuring and positioning of items on the page.

41
Q

SNAP

A

Locks cursor or move to a grid or a specific part of a drawing e.g. corner, centre, end or intersection.

42
Q

STEP

A

Copy selection a number of times.
Each is moved a specified distance from the previous copy in the sequence.

43
Q

SYMBOL

A

A single part from a library.
Often a simple drawing of a complex part which is
used over and over again.

44
Q

TOOL BAR

A

Selection of icons grouped logically which allow the speedy access to parts of the graphics program.

45
Q

TRANSFORM

A

Similar to ‘Distort’.
To take a part of a drawing and distort it mathematically by changing its vertical and horizontal scales together with a possible rotation.

46
Q

TRANSLATE

A

Move a selection of a drawing across a page by a certain amount.
Uses (x,y) coordinates to give new position.

47
Q

UNDO

A

One of the most important drawing tools allowing you to retreat one stage in your work if you have made a mistake.

48
Q

UNGROUP

A
