OK, I finally decided to start my first project in 2014. I drew four walls > auto dimension > then edit dimension.
I noticed that there are now little curved arrows that point to the location of the small offset dimensions ( in this case it was the wall thicknesses ). However whenever I edited the wall length to be shorter the little curved arrows stayed anchored where they were originally and grew in length according to the size adjustment I had made. In other words not something I want on my drawing.
Any idea what is happening and what setting affects this ? I looked back at my dimension settings and arrow setting but don't see anything telling the program to add those arrows and nothing to uncheck to get rid of those arrows ?
