Hi, I believe that dimensions are the hardest objects to handle, for me they are. I want to be able to mirror a drawing. To select the lines and objects isn't that hard to do, but to select the horizontal dimensions, but not the vertical dimensions is something I can't seem to get working. What I tried to do is to select all and then remove items from that selection, but I don't know how to select the vertical dimensions and then remove them. Can anybody help me with this one? Thanks Frank
