Hey, I just had a weird thing happen to me, and was hoping someone could tell me why. I had a structural grid without all the columns placed. I isolated my grid and cols that were drawn in the first floor plan. I selected a col I had already drawn, and tried to do a create similar, and even tried to copy it. None of the new cols would show up. I unisolated everything, and was able to create the cols no problem. Is that a glitch, or did I do something wrong? Thanks.
