Autocad find angle of line

One lap of the circle is and degrees is equivalent to zero degrees on the circle. The mastery of the concept of angles is crucial to your ability to get things done in AutoCAD. You have to be capable of quickly deducing what the value of an angle is from the angle zero. On the images above you will notice the trigonometric circle with angles counted respectively from the positive side anticlockwise and from the negative side clockwise. One of the most important information to have in mind is that AutoCAD always starts counting angles from zero.

Click to set the vertex of the angle that you want to measure. Click where the angle that you want to measure begins. Select Base or Continuous. Select two points to display the distance between the points.

Select another point. When you finish selecting points, press Enter to view the total of the distances. Click a point on the first line. Click the first line at the point where it intersects the second line. Click a point on the second line. The optional dimension label displays the calculated angle between the two lines. To change the precision of primary units, specify the number of decimals to round off to, in the box adjacent to Power Dimensioning tab Dim Text panel Primary Precision Find.

Right angle. Obtuse angle. Straight angle. Reflex angle. Here are the three basic devices used to measure angles. The most common device to measure angles is the protractor. There are some more devices used for measuring angles, and they are: Navigational Plotter. The Sextant. The Theodolite. Miter Saw. A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuring angles. Radian-scale protractors measure angles in radians.
