Autoscale annotation objects

00:04

Annotative objects enable you to create a single annotation

00:08

object that can represent multiple sizes or scales.

00:12

Instead of creating multiple instances of

00:14

an annotation object on different layers,

00:17

you can enable the annotative property of an annotation

00:20

object and assign multiple drawing scales to the object.

00:25

When the drawing scale changes or the annotation

00:28

is displayed in a viewport on a layout.

00:30

The correct representation of the annotation is displayed if

00:34

that drawing scale has been assigned to the object.

00:38

If the new scale has not been assigned to the annotative object,

00:42

it will not be displayed or the annotation object will appear unchanged

00:49

in the exercise file on the model tab.

00:52

You can see some existing geometry as well as several annotation objects.

00:59

Notice that the radial dimension in the

01:01

upper right is larger than the other annotations

01:05

on the status bar. Toggle off the annotation visibility tool.

01:11

When you do the radial dimension disappears

01:15

because it is not set to display at the current

01:19

annotation scale which happens to be 1 to 1.

01:24

When you toggle annotation, visibility back on

01:27

you again. See the radial dimension

01:31

on the status bar, expand the annotation scale tool and select 1 to 4

01:38

when you do,

01:39

nothing appears to have changed.

01:42

But when you toggle off the annotation, visibility,

01:46

all of the annotations disappear

01:49

because none of them are currently set to display when the

01:52

drawing is set to a scale of 1 to 4,

01:56

when you expand the annotation scale tool

01:60

and switch to a scale of 1 to 2. However,

02:04

all of the annotations become visible and they are all the same size

02:09

because they are all set to display. When the drawing is set to a 1 to 2 scale,

02:16

you can easily control which annotative objects display at which

02:20

scales by adding and removing scales supported by selected objects.

02:25

And there are several ways to accomplish this

02:29

on the status bar.

02:30

The annotation auto scale tool is typically toggled off so that

02:35

the program does not automatically add annotation scales to objects.

02:40

When the annotation scale of the drawing or viewport changes

02:44

toggle this on

02:47

then

02:48

expand the annotation scale tool and select 1 to 4

02:54

this time instead of disappearing,

02:57

all of the annotation objects immediately changed size,

03:02

some of them now overlap.

03:04

So you may need to select them and use grips to reposition the annotations.

03:10

But doing this is relatively easy

03:14

since you typically do not want the program

03:16

to add new scales to every annotative object.

03:19

Every time you change the scale of the drawing

03:22

toggle annotation auto scale off again,

03:26

then expand the annotation scale tool and select 1 to 1

03:33

the annotations all change size and position

03:37

and the radial dimension in the upper right disappears

03:41

because it is not currently set to display

03:44

at the 1 to 1 scale.
