I can not seem to keep the oven in the house. I will place a slide in range on the floor plan, then go to the ortho view and voila... Range is half way out of the house... Its magic and I am so new to this program I do not know how to rectify this problem. However, I did not see that symbol on my library either, I had to use two different symbols. On a positive note, the microwave did stay inside the house, just sat on top of the range... Directly on top...
