Ctrl+z is not working

[LeandroSD]

My Ctrl+Z on creo7.0 is not working, it stays grayed out and does not allow me to undo any steps.

Thank you, my friend, but it didn't work.

Hi,

what do you want to achieve with CTRL+Z ?

[LeandroSD]

I want to undo some action in a part or assembly. For example: undoing a command that I made, or reverting an action in an assembly

Hi,

unfortunately your answer is worthless. Please do simple test:

• create new part
• create Extrude feature
• modify one dimension
• press CTRL+Z

Does CTRL+Z work well ?

[LeandroSD]

Yes, it works within the sketch or when I am in some editing action. It does not work, for example:
when I create a command and want to undo the action of that command,

Or when I insert a part and want to undo it, or when I create a command and no longer want it.

Hi,

it means that CTRL+Z can only be applied in some situations. You have to learn to live with it.

Hi.
But I remember that in 4.0, I was able to undo almost the entire modeled part. I believe it must be some configuration.

Hi,

if you are sure then contact PTC Support and discuss the problem with Support Engineer directly.

We just moved from Creo 4 to Creo 6. I haven't notice much difference in what I can undo and what I can not. It seems completely random. Creo has never been very good with undo, in my opinion.

If you think there is a configuration problem, remove all your configuration files (config.pro, creo_parametric_customization.ui, config.sup) and re-start creo and test.

Hello, I haven't found a solution to the problem yet, but I noticed that the command becomes enabled for a brief moment and then it disables again.

[StephenW]

Its very odd that it just goes away after a few seconds. I assume you aren't clicking randomly.

Are you using a start part that was customized by your workplace? 

Try creating an empty part (or assy) without a start model. On my system, I go to File, New, Part, (make sure "use default template" isn't checked, then OK,  then pick Empty.  Test the undo command with that model

Here are a couple of configs that could be causing issues:

sketcher_undo_stack_limit - 200 is default

general_undo_stack_limit - 50 is default

Do you have any Toolkit or other Creo API customizations loaded in your test environment? If so this can cause problems with undo functionality. Even if you do not have company API programs loading you may have it due to use of 3D mouse for example (3D Connexion). If so, create a test environment that does not have any customization via APIs loaded.

Thank you very much, I stopped the toolkits and the command started working normally again. Thank you very much, my friend.
