My selection widows do not work anymore unless I hold down the "right click". Before I could use a regular or crossing window just like always, pick the first point, drag either way and pick the 2nd point. Not now. I have already checked the "Selection" settings under "Options" and they are just like everyone else and also like they are in my plaic AutoCAD 2011. It works just like always in regular AutoCAD so I know it's something specific to my Civil3D. I have verified all of my settings with other users here in the office and they're fine. I have downloaded and ran the latest update, about a month ago I think. It does this in every drawing and it's aggravating.
If anyone has any ideas it would be greatly appreciated.
Thanks, LCTilley
make sure the press and drag box is not checked off in your selection tab of the options. that did it for me.
