Change Annotative Scale In Autocad
Annotation scaling is a new feature in AutoCAD that lets you place Dimensions, Multileaders, Blocks and hatches in Model space, and have them scale to the right size to suit a Paper space Viewport. The Annotation scale feature is a new beast. It can take a while to get your head around and I’ve.
I'm still pretty new to annotation scales and think I'm missing something obvious with the annotation scale in paperspace. I'm working in some of our drawings and when in paperspace the annotative scale is set to 1:1 while others have 1' = 1' and others have 1' = 1'. I want change them to all be the. Annotation objects assigned a fixed text height or object scale remain proportionate in size to the current plot or viewport scale. If the annotative property of an annotation object is enabled, the text height or scale of the annotation object adjusts based on the current drawing annotation or layout viewport scale with the result that it will.
Annotation scale is used to determine text height or the overall scale of an annotation object.
The approach used to calculate an annotation scale depends on whether the object is placed in model space or on a layout.
In Model Space
When annotation objects are created in model space, the following must be considered:
- Drawing or plot scale if plotting from model space.
- Viewport scale of a layout viewport if plotting from a paper space layout.
You can specify different annotation scales for model space and for individual viewports in paper space. When you change the annotation scale, annotative objects and objects with annotative components are scaled accordingly. Connected objects, such as the wires connected to devices, are also updated accordingly. You do not need to regenerate the model.

Shaun Bryant covers the basics of the user interface, showing how to use the ribbon, choose workspaces, and use the ViewCube. The annotative property was added in the AutoCAD 2008 version and it is by far one of the most useful tools of AutoCAD. Prior to induction of annotation scale of AutoCAD, the task of plotting objects with correct scale for different viewports was a tedious job. When AutoCAD ask you to select objects, just type ALL then enter. Now you should see your dimension correctly. Now we are going to add another scale to these dimensions. Activate ‘automatically add scales bla.bla.bla’ in annotation scale group. Change the annotation scale to 1:200. You should see the dimension size adjusted for 1.
The text height or scale of an annotation object in model space can be set to a fixed text height or be controlled by assigning the object an annotation scale. Annotation objects assigned a fixed text height or object scale remain proportionate in size to the current plot or viewport scale.
If the annotative property of an annotation object is enabled, the text height or scale of the annotation object adjusts based on the current drawing annotation or layout viewport scale with the result that it will remain at the same size automatically.
Directly on a Layout
Annotation objects created in paper space on a layout should be created at full size because layouts are commonly plotted at a 1:1 scale. For example, text created with a height of 1/8” in paper space will be output at 1/8” unless a scale other than 1:1 is used to plot the layout.

As most know AutoCAD 2008 was released about 2 weeks ago on March 23. Perhaps the most exciting new feature in AutoCAD 2008 is what is known as “Annotative Scaling”. I have often referred to the 2008 release of AutoCAD as the “your wish is now a command release”, and Annotative Scaling is of the wishes that have been made a command. Using AutoCAD releases prior to 2008 it was common to copy text for printing at different scales. A common one in Civil engineering is 1″ = 50′ for design sheets, and 1″ = 100′ (or larger) for overall sheets. Of the challenges of having multiple copies of a single note is keeping each copy in sync with the other when revisions are made.
The idea behind Annotative Scaling is that you can have a single piece of text which will scale itself up or down based on the scale of your drawing. While powerful the concept and use of Annotative Scaling can be rather complex. A number of pieces must come together in order for Annotative Scaling to work properly. The cool thing is, while I will only focus on text, lots of things including blocks can be Annotative.
Text Style
AutoCAD 2008 introduces a new Text Style dialogue. This change is due in part to the introduction of Annotative Scaling. The key to making text magically scale itself is to make sure the “Annotative” checkbox is checked.
For years we have had to calculate the height of text by doing a calculation such as (Plotted Height X Drawing Scale = Model Space Height). In other words if you were working on a 1″ = 50′ drawing and wanted your text to print at a height of 0.1″ you would; 0.1 in. x 50 ft.= 5 ft. If all of that math confused you, well you’re not the only one. The new Annotative Scaling feature is all about making it so you don’t have to think about anything other than you want your text to plot out at say 1/10″ tall. When the Annotative checkbox is checked the “Height” field changes to “Paper Text Height” (illustrated above). Once again this value is going to be the height you want your text to print out at on paper. You’ll notice I have entered 0.1 in the illustration representing a 1/10″ plotted height.
Annotation Scale
Just as you were beginning to master system variables such as LTSCALE and PSLTSCALE AutoCAD introduces another to us – CANNOSCALE. This new system variable controls how your text will appear in Model space. For instance, if the majority of your plan sheets were at a scale of 1″ = 50′ then you would likely set CANNOSCALE to “1:50”. Assuming you set your Paper Text Height to 1:50, your model space text will be scaled 50x, and consequently appear to be 5′ tall.
Annotation Scale In Autocad
If you have taken a look around your AutoCAD 2008 interface you have likely noticed one addition to the Status Bar at the bottom of the screen. Isumsoft windows password refixer windows 10. These additions have to do with the new Annotative Scaling feature. Instead of typing CANNOSCALE each time you would like to change the Annotation Scale, you can simply click the scale listed on the Status Bar. Clicking the scale will result in a list of available scales being displayed as illustrated to the left. Keep in mind that the Annotation Scale is more or less for reference purposes only. Annotative text displayed in a viewport will be scaled up or down per the viewport scale. Thus it is possible for a single piece of text to be scaled to a height of 5′ in a 1:50 scale viewport, and 10′ in a 1:100 scale viewport.

People who have used AutoCAD Civil 3D in the past will be familiar with the way text can magically scale itself. While Annotative Objects work in much the same way as Civil 3D objects, there are some differences. Figuring out how Annotative Text works can take a little time, but after only a short period of time you’ll find yourself asking “where has this been for the last 21 releases of AutoCAD”. In some future posts we’ll take a look at some of the other things Annotative Text can do.
