[implemented] Undo functionality in tree selection

[sirvinskasp]

Hello,

First time here, so not an expert in FreeCAD.

My job is creating assembly instructions for various electronics. I work mainly with tree selection, so turning layers on/off multiple times. It is very annoying that "undo" [Ctrl+Z] does not work when I'm trying to restore hidden layers/parts, I always have to scroll through the whole tree, find the part that I had hidden by just selecting it in the 3d view and hitting [space] and turn it back on again, when I could have just hit [Ctrl-Z] a couple of times (just like in other CAD software).

I was browsing this forum/wiki/youtube for a long time already but could not find the answer.

Is there a way to fix this? I would really appreciate the answer.

Thanks in advance!

Hello. Welcome to the FreeCAD forum (notice the spelling of FreeCAD ).

What version of FreeCAD are you using? Please always add your full About info when asking for help, it saves time for us trying to troubleshoot issues.

There is a way to do this when changing the Visibility item inside the property editor (View) instead. However, this option is off by default and you have to enable it, first:
* Open the parameter editor (Tools > Edit parameter)
* Navigate to BaseApp > Preferences > PropertyView
* Create a boolean key with the name AutoTransactionView and set its value to true
* Restart FreeCAD

For the tree view we can think about adding this option, too.

Thank you for your response!
The visibility toggle was already there, in the property view, even before I added the boolean key you have mentioned. [Ctrl-Z] still does not work.

I added the boolean key you have mentioned. [Ctrl-Z] still does not work.

And you have restarted FreeCAD? It's important because this key is only checked at program start.

Try this example:
* Swtich to part wb
* Create a cube and select it
* In the View property editor select the item Visibility
* In the combo box select the item false
* In the Undo drop menu click this little arrow => you should see two entries
* Press Ctrl + Z

Does this work for you?

Does this work for you?

Yes, it does! It's quite weird though:
If I use [space], which changes the value to true/false - ctrl+z does not work.
If I change the value manually from the properties view - ctrl-z works.

Now it seems like a bug.

Thanks for such quick answers!

As usual, it is not a bug, it's a the way FreeCAD (FC for short) will work, probably some actions are not added to the "undo stack".

@wmayer that is one of the lead developer, has answered you,:

Probably something will happen in future.

Doing it with property editor is a workaround.

Now it seems like a bug.

It's a missing feature. I will implement it shortly.

Wow, thanks! I will wait patiently.
I was already busy creating a workaround using macros. No success unfortunately.
