Symbol elements, such as furniture and light fixtures, are oriented in a logical fashion when you insert them in your drawing. For example, tables are inserted in a flat, upright position on the floor, and electrical outlets are inserted in a vertical position on the face of walls. You can edit the orientation of most symbol elements. For example, you may want to flip an air register so that you can insert it on the ceiling in your basement.
