Bearings are used by surveyors, geologists, and mapmakers. For a detailed discussion of bearings, see online Help. Standard and compass angles use the same system of notation. To enter an angle using the keyboard, simply enter the angular value followed by any of the following angle notations: Angular Unit degrees Notation #.#d Examples 45.00d degrees-minutes-seconds #d #' #'' 19d 18' 45'' minutes #.#' 47.5' seconds #.#'' 15.3'' radians #.#r 0.7845r grads #.#g 1.25g bearings N|S#d#'#''E|W N|S#.E|W N14d8'15''E S30.W NOTE # represents a signed, whole, decimal, or exponential number (e.g., 3, 4.123, 5e20). You can also enter angles using the mouse. Entering angles with the mouse is handy when you need entities to have the same orientation. You can enter an angle with the mouse by: s Entering three points in the drawing. s Entering two points in the drawing. s Clicking an arc, line, polyline or polygon segment, text entity, marker, or symbol. To enter an angle on the edit bar based on three points 1 Select an entity in the drawing. 2 Place the insertion point in the Angle text box and press CTRL+ENTER. 3 Enter the vertex (the center point) of the angle. 4 Enter a point that defines the beginning point of rotation. A rubber-band arc appears. 5 Enter the ending point of rotation. 122 | Chapter 10 Entering Lengths & Angles
