Update: We released a free e-book that you can use to learn annotation scaling. You can download it here: Free e-book: Working with AutoCAD Annotation Scaling. We suggest you to download it because it contains more information than this article.
Annotation scaling was introduced first time on AutoCAD 2008. I love this feature. This feature adds benefits to AutoCAD layout. There is some work around AutoCAD users do before this feature exist. But now, presenting our drawing in different scales is very easy and quick. If you are interested in learning this feature, this tutorial will be an excellent reading to start.
First, what are annotations?
Annotations are every object in your drawing which is not a model or geometry. We use it to show dimensions, text as description, symbols, and pattern to show sections, materials, etc.
The problem with annotation occurs when you need to represent your drawing in different scales.
Two images above are the same model in two different viewports, with different scales. If we draw the model and prepare it for a particular scale, say 1:100, when we need to represent the drawing in 1:200, the text, hatches, and all other annotations will be shown in half size to what we expected.
AutoCAD users used to create annotations in the layout. But there are some downsides.
- It works for text and dimension, but not for hatches.
- You may need to create more than one annotation to the same object if you show them in different viewports. When you need to change the text content, you will have to change them all manually. Sometimes you left some of them unchanged.
- When you move the viewport, some annotations might be left behind.
So, if you have those problems, you may love this feature.
Download and open this drawing. We are going to continue using the same drawing. Change your active scale from annotation scale list. It’s on your status bar. Change it to 1:100. We are going to set our drawing for 1:100 first.
Now open your dimension style. You should see a style named ‘1-100 3mm’. Right click on it, and rename it to ‘3 mm’. Click Modify button on the right side of this dialog box.
On the FIT tab, scale for dimension features section, activate Annotative.
- On the Text tab, change text height to 3, offset from dimline to 1.
- On Symbols and Arrows tab, change arrow size, center marks, and break size to 2.5.
Close the dimension style dialog box.
You see all your dimension text and arrow too small? Don’t worry. We need to update them to apply the changes.
Activate update in dimension panel, annotation tab. 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 1:200 scale! Turn off the ‘automatically add scales…’ again. Try to change it to 1:50. What happen? Nothing.
Open your layout. Select the left viewport border, and change the scale to 1:100. Press [esc] to deselect the viewport. Select the right viewport, and change the scale to 1:200.
Compare the dimension size on those two viewports. Even the viewports have different scales; the dimension size will always be the same! When you plot this sheet, the text in all viewports will be 3mm.
We will discuss more about annotation scale in the next post.
I have problem when I click “Update” in dimension panel the AutoCAD applications gets stuck and the following error appears as a buuble in the windows task bar notification panel: “Display driver stopped responding and has recovered”
I am using AutoCAD 2012 (64-bit) and have a 1 GB dedicated nVIDIA card. I doubt this occurs because it requires more GPU memory. I am not sure though. Is there any other way to update the dimension style in a less memory intensive way?
Thanks very much for this topic,I feel gaining my understanding in autocad
waiting for more lectures
The tutorial is perfect. I have been blind for more then 7 years.
Edwin, thank You very much for this useful topic.
ok … mr edwin : can you answer ?
which of these can’t use annotative scale ?
1- hatch pattern
2- revision cloud
3- block
4- attribute
Zee,
Only revision cloud can’t use annotative. You can use annotative scale for the other objects.
good morning mr edwin …
revision cloud is using annotative scale ? thanks ..
Good morning.
No, revision cloud is not annotative.
It works for text and dimension, but not for hatches,,,
really hatch don’t use annotative scale ,,,,
what do you mean ? and how ? annotative scale doesn’t work with hatches …
Zizo,
You need to set the hatch to annotative when you create it. Or you can modify it later in properties palette.
Check the ribbon, contextual tab when you create the hatch.
Hi Edwin,
Many of CAD users around me do not know about this. When i showed this, they just appreciated.
All credit goes to you. Thank You.
I have one small query. It looks perfect when there is only one dimension. If we need to show many dimensions (element to element, overall) in same side, the dimension overlaps in lower scales. How can we overcome this problem.
Thank you Nirmal,
Have you checked this article? https://www.cad-notes.com/controlling-annotation-scale-further/
It covers about annotation scale further, and it guides you how to control appearance in different scale.
hai dude’s…
im study for architectural.. first im using ‘microstation’ after tat using ‘Gstar Cad’ n now using autocad 2007..
autocad im using when im studing time oni… after tat start using differents software in my working firms..
can u teach me how to draw the site plan n pls show me the format calculations…
its very hard to find.
pls help me… frend..
tq..
this awesome
really helpful
big up for the work you are doing
Thank you for posting all these informations on your site. It helps me a lot to get to know AutoCad better and use it in a more efficient way. I have your site in my bookmarks and I will learn from it a lot I guess.
