Polar Tracking
Polar tracking lets you specify angles at which to draw. Polar tracking is similar to Ortho mode, but unlike Ortho, polar tracking merely indicates your specified angles and does not force you to draw horizontally or vertically like Ortho does.
Step 7. Set polar tracking angles at 15°, as described next:
polar tracking: A means of specifying points using your own increment angle.
Prompt
Response
Type a command:
Place your mouse over Polar Tracking on the status bar and right-click
A right-click menu appears:
Click Tracking Settings…
The Drafting Settings dialog box appears with the Polar Tracking tab selected:
Click the list under Increment angle: and click 15 (as shown in Figure 3-48)
Click OK
Polar Tracking (<F10>): Shows temporary alignment paths along specific angles of interest (for example, 15 degrees). Although the default increment for PolarSnap is 90 degrees, one can change it easily to 60, 45, 30, 15, and so on, as shown in Figure 3-48. You can use the system variable POLARANG to reset PolarSnap.

Step 8. Use the LINE command with direct distance entry and polar tracking to draw the inside lines of the conference room walls (Figure 3-49), as described next:
