Exercise 9
1. Start AutoCAD 2010.
2. Open the fi le
Exercise_09.dwg
.
3. Using
Ortho
and
Direct Distance Entry
, draw the following shape
(without dimensions) using the
Pline
command with width = 0.1.
4. Save the fi le and close it.
Take note of the following tips:
In order to draw the large arc, use angle = 180.
Before you draw the last arc, change the mode to
Arc

2.11 POLAR TRACKING
°
We learned that we can force the cursor to give us four orthogonal angles
(0, 90, 180, 270) using
ORTHO
.
If we want other angles, such as 30 and its multiples or 60 and its multiples,
ORTHO
would not help us. For this reason, AutoCAD provides another
powerful tool called
Polar Tracking
.
Polar Tracking
allows you to have rays starting from your current point
pointing toward angles such as 30, 60, 90, 120, and so on. You can use
Direct
Distance Entry
just as we did with
ORTHO
.
On the
Status Bar
, click the
Polar
Tracking
button.
