Correcting mistakes means you can't go forward in time again?

Hello,

So annoying that if you make a mistake and go back in time a bit too much.. You can't go forward again?

Any one else find they've had the same problem? Although I'm sure you can! But how??

Adam

Can you post an example that exhibits this behavior?

Is this an AutoCAD question or is it an AutoCAD Architecture question?

You could always do a "save as" before getting in that time machine and going back in time Dr. Who.

Autocad will only "redo" a single undo, so if you are going to back up through a drawing using undo, you should do as Remark said and saveas, or hit save before you undo. Then if you miss, simply close the drawing without saving it again and you'll be back where you started. You should be aware that if you use either method, you won't be able to undo from that point. Once you close the drawing, all undo and redo information is lost.

That is something that has always bugged me how dozens of undo steps can be remembered, yet redo steps can't be remembered like in a lot of other software programs. I guess it prevents inducing any errors accidentally though.

In Autodesk Inventor you can Undo/Redo all the way back to starting the file and finishing the part (within reason, there are certain dependencies that can be created that cannot Redo, but if using the BORN Technique these dependencies can be largely avoided). I use this functionality to show my students how a part was created forward and backward. History based modeling takes some discipline, but once you learn the techniques it becomes a second nature as driving a stick shift transmission - you just do it without thinking.

Interestingly, another history based MCAD solution - SolidWorks - is far less forgiving on Undo/Redo.

I don't know if this is still true but in r14 there is a mechanism in the UNDO command to "Mark" your current position. Then you can undo to some point with UNDO...Back bringing you back to the marked position. Also there is a Begin...End mechanism. Look at the UNDO command in your help file.

You can do this in 2010 if you set an "undo begin" point. You can then do things to your drawing, then undo back to the begin point in a single action if you wish or one step at a time. Or by placing a mark in this sequence, you can use "back" to go the point at which you placed the mark. You can place as many marks as you want.

I had forgotten, because I've only used it once or twice, but there is an MREDO in 2010. It will let you redo an number of undo actions. You're options are "number", "all", or "last".

I've not used it much myself Jack - mostly because I don't often make any mistakes.

 

It's like a lot of things in AutoCAD, unless you use something you tend to forget it's there or forget how to use it. And in many cases it is a little cumbersome to use and takes some practice to understand how to use it.

Yeah me either (insert smiley of me walking on water)! I use undo for little stuff like if I'm erasing with a crossing and grab unintentionally grab something, or insert the wrong block...stuff like that. A long time ago I got in the habit of hitting the save button frequently. That does two things for me...one, I don't lose much if there's a crash, and 2, if I want to take off and explore a variation of the design, hit save, then saveas and do the exploration. If I don't like it or discover that it doesn't work or whatever, my original drawing is intact. I even do this during the "exploration" as I called it, and will have several versions saved. For instance, say I'm working on a drawing called "elm street house" and decide to try different floor plans. By the time I'm done, I'll have "elm street house", "elm street house2", "elm street house3" and so on. That way I can gather bits that I like from any of the variations and combine them. I find this saves time and effort over undoing back to whatever point, and you can preserve all that work for future use if you wish. Never draw any twice if you don't have to!

--edit-- "grab unintentionally grab something"....sheesh. That's what we need undo buttons for!!!

Jack, all good habits to get into. My save button is beginning to show signs of wear. I'm sure it will need replacement soon.

Save button... Ctrl - s all the way!

Thanks for all your help!! Just goes to show 2 minds (or in this case 5/6) are better than 1!
