I am using Civil 3D 2013, Windows 7 x64.
Intellizoom does not seem to work properly on certain drawings, where if I undo... nothing happens. Rather, it tries to undo *each* click of my scroll wheel, without doing anything. This results in dozens and hundreds of undo commands, most of which are totally useless. This of course breaks my undo command, rendering it almost pointless. If I make a change, zoom out and decide that the change is not needed, I cannot easily undo; I have to undo something like 50 "commands" that do nothing, before I get to the "real" undo that I wanted to undo in the first place.
I understand there is the "Combine zoom and pan commands"; this is checked off. It does not seem to do anything. How do I make my undo command useful again? As a keyboard user, I want to use ctrl-z for my undos. I do not want to go to the undo button, pull down the menu, and search trhough the 50 commands to find the correct command to undo to, especially since I never had this problem before in previous versions of Civil 3D.
Some additional information:
1. I can open some other drawings that get the correct undo/zoom behaviour.
2. I can open the drawing I have problems with using a previous version of Civil 3d (2012), and get the correct undo/zoom behaviour.
I have no idea what it means other than that it's what shows up under the undo pulldown tab when I try to undo a (mousescroll) zoom command. If you try a mousescroll zoom and check that, it should show up.
I have had a Thinkpad Trackpoint USB keyboard hooked up to this system in the past, but I have confirmed that neither that keyboard nor the associated software (or drivers) is currently running.
Also, when I open a different drawing using Civil 3D 2013, or when I use Civil 3D 2012 with my current drawing (which obviously I can't work with), I do not see this behaviour.
We are experiencing the same issues. The only mouse software we have installed is the drivers that are installed by windows when you plug in a mouse.
Type UNDO and make sure AUTO is On.
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]
Not sure if this will help. But it's the only thing I've found in the Undo command that might have an affect.
I have the same problem and its annoying as h... please Autodesk do something about this. Judging by other post on this forum, this has been a problem for at least two years. My experience is that the problem increases the longer I work on the drawing.
It seems to be some sort of interaction with dense hatches. If you either delete or "dedensify" hatches, you will again be able to undo properly.
