Annotation scale not changing

Anonymous — Sun, 19 Apr 2020 03:09:14 GMT

Please please please help. I cannot find any article or post that can help me.

I have scaled a drawing in autocad, however the annotation scale will not change in model space. Yes i have changed the "Annotation scale or current view" to every option but it doesnt change at all. I am going crazy. This is so simple in other programs!

Please see attached images of what im seeing. Im pretty new to autocad so please go easy on me.

@Anonymous hi,

in AutoCAD Model tab (space) to have a drawing in another scale does not require scaling. instead you should plot it at the right scale. for example if your drawing is in mm and it is scaled to 1:50 and you want it in 1:100? you plot it at 1=100 plot ratio (of course there is need to fix the annotative objects [like texts, dimensions] to the new scale)

by doing a scale of 0.5 (for example) you took a measured line of 10000mm and made it 5000mm. that's means if you draw a new dimension on it you will get a measure of 5000 but it's not?!

what happened to you is after scale, although the drawing scale went down but the dimension global scale (known as global dimscale) was not cause dimensions are controlled by a dimension style and each scaled drawing need to have it own dimension style.

So to fix the state you entered, you need to scale the drawing back up and correct the global dimscale for the current dimension style. but the better way for you it is to create a new dimension layer and copy the existing dimension to that new layer, create a new dimension style with the corrected global dimscale and apply the new dimension style to those copied dimensions and yes i know maybe some will jump in now and say there is other way to do it and it's call annotation scale so i say to them: the op is a beginner and before he use annotation scales he need to learn how to use dimension and dimension styles 😀

Hi,

>> I have scaled a drawing in autocad

Which way did you scale the drawing content? Using _SCALE command does not change some parameters of the dimension objects.

If you are scaling because you want to have the drawing build with other units you might try -DWGUNITS instead, one of the last questions is if you want to scale the drawing content based on the units-difference/factor. This handles dimensions better.

Hi,

>> I have scaled a drawing in autocad, however the annotation scale will not change in model space.

you have here two separated command ( procedure ) , and some how they aren't related . Annotation scale is used for Annotative objects . You can control the method that an annotation object is scaled by defining the object either as non-annotative or annotative.

Non-annotative objects, require a fixed size or scale that is calculated based on the scale used to plot the drawing.
Annotative objects automatically adjust to display uniformly at the same size or scale regardless of the scale of the view.

So the idea here is to define your objects first to be Annotative objects then you can use Annotation scale for that .

In your after screenshot, it does indeed looks like your annotative scales did change: perhaps you are looking for another solution and using the wrong terms?
Post your DWG file and better explain what problem are you trying to overcome specifically without mentioning "annotation scale".

TIA

Thanks for all of your replies. I will go through them when i have time! in the mean time if just deleted scales of imported drawings and re-done it with my own scale style. cheers.
