The Door tool allows you to place a variety of doors by clicking on parallel lines in the drawing. The tool provides a wide variety of options and detail.
Architects vary widely in the way they draw doors.
Some regard doors as a symbol only and use the minimum amount of detail to show the door, while others are compulsive about showing details of trim, stops on the door frame, sills and thresholds. The Door tool attempts to serve the full spectrum of users by placing these decisions in your hands. You pick the type of frame, threshold, door angle, frame size, setback, etc. To place a door, you click on one wall line, drag to the second wall line and then move the cursor to locate the door.
