A fast method for entering distances is to point in a direction with a rubber-banding line and then enter the distance through the keyboard. For example, to draw a line 3 units long from left to right, click the Line tool on the 2D Draw control panel, click a start point, and then move the cursor so the rubber-banding line points to the right at some arbitrary distance. With the cursor pointing in the direction you want, type 3↵. The rubber-banding line becomes a fixed line 3 units long.
Using this method, called the Direct Distance method, along with the Ortho mode or Polar Tracking can be a fast way to draw objects of specific lengths. Use the standard Cartesian or polar coordinate methods when you need to enter exact distances at angles other than those that are exactly horizontal or vertical. If you have the Dynamic Input display turned on, you can set the angle of the rubberbanding line using the angle display as a guide and then enter the distance you want through the keyboard followed by a ↵. Lines are drawn to the nearest whole degree shown in the Dynamic Input display.
On some systems, the AutoCAD Blipmode setting may be turned on. This causes tiny cross-shaped markers, called blips, to appear where you select points. These blips can be helpful to keep track of the points you’ve selected on the screen.
Blips aren’t part of your drawing and don’t print. Still, they can interfere with your work. To clear the screen of blips, choose View Redraw, or type R↵. The screen quickly redraws the objects, clearing the screen of the blips. As you’ll see later in this book, Redraw can also clear up other display problems.
Another command, Regen, does the same thing as Redraw, but it also updates the drawing-display database— which means it takes a bit longer to restore the drawing. Regen is used to update certain types of changes that occur in a drawing.
To turn Blipmode on and off, type blipmode↵ at the Command prompt, and then enter ↵ or off↵.
