Why is the 1:1 scale being added?

[h_s_walker]

In the attached drawing you will see a block with a 1:50 scale and a 1:1 scale.

The problem is I didn't add the 1:1 scale and it's not added in the block itself.

If I use ADC to drag it from it's source drawing into a blank drawing it doesn't add it.

It does it if I use the tool palette icon I created for it. However as you can see in the image below 1:1 is nowhere to be seen.

Dumb question if I may: how is that affecting your workflow or task?

[h_s_walker]

Not a 'totally' dumb question.

I don't like having multiple scales in my blocks if I can help it.  And the 1:1 is just annoying as I have other annotative blocks which aren't doing that at all and they are only inserting in the scale I choose

EDIT: It's just done it on another block of mine, and I can't get rid of it

@pendean Below is the problem. The white "circles" and the red "circle" are both the same block.

The red circle only has 1:100 as a scale. The white "circles" have both 1:1 and 1:50 and the B-04 is 1:200

The scale in modelspace is set at 1:20 and the text in the block is non annotative, but the block is annotative.

As you can see it messes up my blocks totally

I have the exact same problem.  How does it affect workflow you ask?  All text in model space changes to 1:1 annotative scale on its own if the scale you are currently drawing in is changed.  I draw most elevations in 3/4" scale, but most sections in 1-1/2" scale.  As I change scales back and forth my labing in model space changes to 1:1 which makes it impossible to read.  

This just started happening.  I have used the same blocks to label my drawings for many years.  I thought I messed up a setting somewhere, but with this user having the same problem it has to be a bug of some sort.  Or, we both messed up something.  

[JeffKD411IWS]

I am having the same problem.  I thought I messed up a setting somewhere.  I doubt we both messed up the same setting, but that could be possible.  I have tried everything to remove that extra 1:1 scale from the annotative scale list, but every time I insert it from the Tool Palette it comes in with the extra scale and i cannot remove it once the block is inserted.

@JeffKD411IWS glad to see I'm not the only one having problems.

I can remove the 1:1 scale from my blocks, but changing the scale in model space is shown in the picture I posted.

The really annoying thing is some of the blocks on my tool palette which are also annotative do not add the scale.

I tried deleting the block from my tool palette and then reinserting it and it happened again.

Also what's weird is if you use design center to drag the block into the drawing it doesn't add the 1:1 scale

[JeffKD411IWS]

Yes I have tried creating a new block in a new reference file and even that block got a 1:1 scale added to it when inserted from the Tool palette.  If I copy and paste the block from the reference drawing into the working drawing the scale is not added.  It only happens when coming from the tool palette.

Some more information I have found...

I had an old exported settings file from AutoCAD 2023.  I reverted back to 2023 and restored my settings from back then and all the blocks that came in from the tool palette did not have a 1:1 scale added, everything worked correctly.  I then exported those settings into 2024, and then exported settings again up the 2025.  No 1:1 scale was  automatically added in 2023 or 2024, but in 2025 the same problem is still there.

So for me, 2025 is the issue as far as I can tell.  Not sure if that is the same for everyone, I figured maybe this information could help you.

Seems like it will have to be escalated

[dillonlagrange80RKWTC]

I've started to have this same problem. It's annoying because if I switch to an annotative scale that's different than any block in the model space, the text shrinks down to 1:1 and becomes illegible while I'm working. So then I have to switch scales just to read something. It didn't used to do this. The text used to just stay at the scale I set it at and even if I switched scales, I could still read the blocks set to other scales. One thing I have noticed though is that it only happens to blocks with dynamic functions. Other plain blocks don't get the 1:1 added. And as was already noted, it only happens when the blocks are pulled from a tool palette. I still don't know the solution but I'm hoping someone can figure it out.

I am having the same issue and is causing problems when drafting as the annotative dynamic blocks change scales when they shouldn't which makes the drawing very messy and often illegible.
I have logged the issue with customer support, hopefully can be fixed.
If interested here is another thread with same issue that suggests a temp workaround.

FYI reply from Customer support in case anyone else is having the same issue:

Thanks for contacting Autodesk Technical Support Team.

This is Sophia Lee who will be assisting on '1:1 scale being added to dynamic annotative blocks inserted from Tool palette'.

This is known issue for 2025 and has been fixed in AutoCAD 2026 version which was released 2 weeks ago. AutoCAD 2024 version is also working as expected. But I would highly recommend to use our latest version of AutoCAD which has many enhancements!

Hope this is helpful.

Kindly let me know if you need further assistance. 

Look forward to hearing from you soon
