Setting the Polar Tracking Angle AutoCad Help

You’ve seen how Polar Tracking lets you draw exact vertical and horizontal lines, You can also set Polar Tracking to draw lines to other angles, such as 30 or 45 degrees. To change the angle Polar Tracking uses, you use the Polar Tracking tab of the Drafting Settings dialog box.

Capture

Open this dialog box by right-clicking the POLAR button in the status bar and then selecting Settings from the popup menu. Or you can select Tools >.Drafting Settings from the menu bar and then click the Polar Tracking tab.

To change the Polar Tracking angle, enter an angle in the Increment Angle input box, or select a predefined angle from the drop-down list. This can be done while drawing a series of line segments, for example, so that you can set angles “on the fly.”

There are numerous other settings available in the Polar Tracking tab. Here is a listing of their functions lot your reference:

Additional Angles This check box and list box let you enter a specific angle for Polar Tracking. For example, if you want Polar Tracking to snap to 12 degrees and only 12 degrees, click the New button next to the Additional Angles list box and enter 12. The value you enter <lPPCMS in the list box, and when the Additional Angles check box is checked, Polar Tracking snaps to 12 degrees. To delete a value from the list box, high height it and, click the Delete button.

The Additional Angles option differs from the’Increment Angle setting in that the Increment Angle setting causes Polar Tracking to snap to every increment of its setting while Additional Angles only snaps to the angle specified. You can enter as many angles as you wish in the Additional Angles list box.

Object Snap Tracking Settings These settings let you control whether Object Snip Tracking uses strictly orthogonal directions (0,90,180, and 270 degrees) or the angles set in the Polar Angle button group of this dialog box, See Listing Objects Using Object Snap Tracking later in this chapter.

Polar Angle Measurement These radio buttons let you determine the zero angle on which Polar Tracking bases its incremental angles. The Absolute option uses the current AutoCAD setting for the 0° angle. The Relative to Last Segment option uses the last drawn object as the 0° angle. For example, if you draw 1 line at a 10° angle, and have the Relative to Last Segment option selected with the Increment Angle set to 90, Polar Tracking snaps to 10, 100, 190, and 280 degrees, relative to the actual 0° direction .
