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.
