11. Add lines on the Ceiling layer to represent the door header.
12. Draw lines between the two jambs (on the Door layer) to indicate a sliding-glass door (see
Figure 6.19).
The wall facing the balcony is now complete. To finish the unit, you need to show a handrail and
the corners of the balcony wall:
1. Offset the bottom line of the balcony 3˝ toward the top of the drawing. Metric users should
offset the line 7.6 units.
2. Create a new layer called F-rail, and assign this offset line to it.
3. Add a 5˝ (13 cm for metric users) horizontal line to the lower corners of the balcony, as
shown in Figure 6.19.



4. Choose Draw  Block  Base from the drop-down menu to set the base point at the lowerleft
corner of the balcony, at the location shown in Figure 6.19.
5. Assign the lines indicating walls to the Wall layer, and put the sliding glass door on the Door
layer (see Figure 6.19).
6. Zoom back to the previous view. Your drawing should now look like Figure 6.20.


7. Choose File  Save to save the drawing, and then close the file.
Your studio apartment unit plan is now complete. The exercises you’ve just completed demonstrate
a typical set of operations you’ll perform while building your drawings. In fact, nearly 80 percent
of what you’ll do in AutoCAD is represented here.
Now, to review the drawing process, and to create a drawing you’ll use later, you’ll draw the
apartment building’s lobby. As you follow the steps, refer to Figure 6.21.


The Construction Line Options
There is more to the Construction Line command than you’ve seen in the exercises in this chapter. Here
is a list of the Construction Line options and their uses:
Hor Draws horizontal Construction Lines as you click points
Ver Draws vertical Construction Lines as you click points
Ang Draws Construction Lines at a specified angle as you pick points
Bisect Draws Construction Lines bisecting an angle or a location between two points
Offset Draws Construction Lines offset at a specified distance from an existing line
As is usual in floor plans, the elevator shaft is indicated by the box with the large X through
it, and the stair shaft is indicated by the box with the row of vertical lines through it. If you’re in a
hurry, use the finished version of this file called Lobby.dwg (Lobby-metric.dwg for metric users).
To draw the apartment-building lobby, follow these steps:
1. Create a new file called Lobby, using the Unit file as a prototype. (Open the Unit file, choose
File  Save As, and enter Lobby for the new filename.)
2. Erase the entire unit (choose Erase  All).
3. Draw the three main rectangles that represent the outlines of the stair shaft, the elevator
shaft, and the lobby.
4. To draw the stairs, copy or offset the stair shaft’s left wall to the right a distance of 4´ (122 cm).
This creates the first line representing the steps.
5. Array this line in one row of 10 columns, using 11˝ (28 cm) column offset.
6. Draw the center line dividing the two flights of stairs.
7. Draw the elevator, insert the door, and assign the door to the Door layer. Practice using
Construction Lines here.
8. Draw the door jambs. Edit the door openings to add the door jambs and headers.
9. Use the Base command to set the base point of the drawing. Your plan should resemble the
one in Figure 6.21, step 4.
10. Save the Lobby file.
