I'm using Revit 2014.  Since I moved to 2013 and then 2014 Revit keeps giving me this error message when I try to alter many of my previously existing walls.  This never happened in 2012, so it feels like this has to do with Revit, not my walls.  Has anyone else experienced this or know of how to sort it?

(these are not foundation walls, which is basically what came up when I searched for this error)

You are talking about existing elements that were coverted, not copied into a new file - correct?  If they are copied then I suggest user error.

Otherwise, look at the properties of one of these walls when the error occurs.  Perhaps the location level is incorrect.  Post an image of the wall properties.

THis happens to me all the time.... usually when I'm in a hurry... unfortunately, it is caused by user error! (Using R2013)

I feel your pain! I want to know why it happens as well - i never seem to be able to draw a wall from scratch and not get an error message, and it never lets me draw the wall to the base and height that I enter...

Always look at the properties BEFORE you pick the first point of your wall.

I found out yesterday that it is the way the walls work, whether you use an architectural wall vs a structural wall - i use structural walls because I do structural drafting - Structural Walls like to go from the top down (by depth) Rather than top up (by Height) and if you change the depth to height in the options bar (at the top) and enter your properties BEFORE you pick the first point of your wall, then those properties will remain for your next wall, etc.

Wall Base Offset... one works, one doesn't. Why?
