If You Would Like More Practice…

If you would like to practice the skills you have learned so far, here are some extra exercises.

An Alternate Sliding Glass Door

Here is a simplified version of the sliding glass door of the cabin . It doesn’t include any representation of the panes of glass and their frames .

To draw it, use a technique similar to the one described in the previous section. Copy the jambs for the 7' opening to the right, and draw this door between them.

An Addition to the Cabin

This addition is connected to the cabin by a sidewalk and consists of a remodeled two-car garage in which one car slot has been converted into a storage area and an office (see Figure 4.49). Use the same commands and strategies you have been using up to now to draw this layout adjacent to the cabin. Save this exercise as Cabin04c- addon .dwg .

Figure 4.49: The garage addition

Refer to this chapter and the previous one for specific commands. Here is the general procedure:

1. Draw the two lines that represent the walkway between the two buildings .

2. Draw the outside exterior wall line.

3. Use Offset, Fillet, and Trim to create the rest of the walls and wall lines.

4. Use Offset, Extend, and Trim to create the openings.

5. Use Rectangle and Arc to create a swinging door.

6. Use Copy, Rotate, and Mirror to put in the rest of the doors.

7. Use Offset, Line, and Copy to draw the storage partitions.

Draw Three Views of a Block

Use the tools you have learned in the last few chapters to draw the top, right side, and front views of the block shown in Figure 4.50.

Figure 4.50: The block

Below is a graphic representation of the twelve steps necessary to complete the exercise.

Here are the 12 steps in summary that correspond to the 12 drawings. Start with the top view:

1. Start a new drawing. Leave all settings at the defaults. Use relative polar or relative Cartesian coordinates and the Line command to draw a rectangle 17.75 wide and 11.51 high.

2. Offset the bottom horizontal line up 2.16 and the new line up 4.45.

3. Offset the right vertical line 4.75 to the left and the new line 3.50 to the left.

4. Use the Trim command to trim back lines and complete the view.

Next, do the right side view:

1. Draw a vertical line to the right of the top view. Make it longer than the top view is deep.

2. Offset the vertical line 2.4 to the right, and then offset the new line 2.4 to the right also.

3. Use Endpoint Osnap to draw lines from the corner points of the top view across the three vertical lines.

4. Trim the lines back to complete the side view.

Finally, draw the front view:

1. Draw a horizontal line below the top view. Make it longer than the top view is wide.

2. Offset this line 2.4 down, and then offset the new line 2.4 down.

3. Use Endpoint Osnap to draw lines from the corner points of the top view, down across the three horizontal lines.

4. Trim the lines back to complete the view.

This ends the exercise. There are ways to rotate and move each view relative to the other views. We will look at those commands later in the book, and draw more views in Chapter 8.
