Undo command disabled?

Why is my UNDO command disabled?

REINSTALL YOUR CAD THATS THE ONLY WAY TO GET YOU UNDO TO WORK RIGHT. I TRIED EVERYTHING AS WELL BUT NOTHING WILL RESTORE IT BUT AN REINSTALL.

Type UNDO at the command-line and select option "One".

Now, the U command undoes one command at a time.

If this doesn't work, type UNDOCTL at the command-line, and tell us what value this is set to...

That appears to work. But only after I typed UNDO a second time. The first time I typed UNDO and entered 1. Autocrat replied that I needed to enter a number from 1 to 3####. You know a typical Autocrat WTF answer.

Second time around and it worked.

Thanks.

Hmm..

How about

UNDO

CONTROL

ALL

What does UNDOCTL give you?

[Anonymous]

UNDOCTL = 48 (read only)

[rhesusminus]

And if you type

UNDO

CONTROL

ALL

what's the value for UNDOCTL then?

[Anonymous]

UNDOCTL = 53 (read only)

OK another reason to hate Autodesk. Appearently this has been happening since 2008 Electrical

I am so glad that I get to use software that's had the same bug for over 5 years that dirrectly effects using the software. Thank you  Autodesk.

Command: u U command disabled. Use UNDO command to turn it on

Write the command twice and then its works... 😄

[controldesigns]

I tried everything listed in the forum, nothing worked.

Finally, I found a combination that worked.

UNDO
Current settings: Auto = On, Control = All, Combine = Yes, Layer = Yes
Enter the number of operations to undo or [Auto/Control/BEgin/End/Mark/Back] <1>: A
Enter UNDO Auto mode [ON/OFF] <On>: OFF

I turned Auto mode OFF and now Ctrl+Z works properly again...

For me anyway!

Okay, I'm back. So it worked in one drawing!

I tried it in another drawing that I had open in a different tab and it didn't work.

Why in the world would undo (control+z) stop working in the first place Autodesk?

Please help

I'm using 2023 Electrical

[colincampbell]

I am having the same trouble and nothing provides a lasting fix.  Sure I can fix it in one drawing but then I open another drawing and the same thing happens.

Why would anyone want UNDO disabled. 

I'm using Autocad Electrical 2022

[jseefdrumr]

I have access to both 2021 and 2023 and I can't even reproduce the issue.

One thing to try is to add UNDOCTL to the system variable monitor so you at least get notified when it changes. Then, it may become easier to at least identify why this is happening.

[controldesigns]

I also noticed that when I load a drawing, I get this message
"WD_ARX_FORMAT_PATH"
If that helps?

[controldesigns]

I'm sorry, my last email left an important part of the message off.
Here is the full message:

"AutoCAD Electrical menu utilities ; error: no function definition: WD_ARX_FORMAT_PATH"

Good God... losing 'Undo'?  That sounds terrible!  Sadly, all I have to give here is sympathy.  For all the new stuff they cram into the software year after year, it's frustrating to hear of a long-term bug in (of all things) 'Undo'!

[jseefdrumr]

I literally LOL'd at "all the new stuff they cram into the software year after year"

ACADE basically hasn't had a true new feature for at least five years. Even longer if you discount the SQL support they added a while back. We don't even get the cool stuff that Vanilla ACAD gets, dynamic blocks were introduced 16 years ago and we're STILL waiting on support for them in ACADE.

Back to the OP though. Whatever the UNDO issue is, doesn't appear to be happening to Vanilla ACAD, I can't find any forum posts about this anywhere but here in the Electrical forum. However, as for the arx format error, here's an old thread that addresses that. Perhaps this will help on that front, at least.

Has the system variable monitor provided any insights?

[mrackAUZYE]

Ah, gotcha... yeah, I'm kinda new here.  I've been in ACADE for about a month... ACAD/Inventor for 25 years, so that's where I'm coming from.

[jseefdrumr]

No problems. You'll get used to it, lol. I've been using ACAD and/or its verticals since the turn of the century. ACADE is fine for most of what I do but it doesn't get the developmental attention that I think it needs. We keep seeing issues like what the OP presented here, which don't seem to have a parallel in Vanilla ACAD. It's weird that some stuff only happens in ACADE but I usually chalk it up to this software being overlooked by the devs.

Sometimes we're stuck with straw-grasping to identify the source of a problem and find a workaround. I'm hoping the OP can find some information in the sysvar monitor that will shed light on this one. It's weird.
