Edit Bar controls: Fixed Text, Align dimension, Text mode, Width, Height, Small angle, Settings, Favourites.
The tool allows you to dimension the angle between any two lines. It does not matter whether the two lines actually cross, so long as they are not parallel.
Checking Small Angle will generate angular dimensions less than 180º, whilst unchecking the Small Angle option will draw angular dimensions greater than 180º.
See Dimension General for standard Edit Bar controls.
This tool applies a Single Dimension mode.
Pick the first line from which any angles are to be calculated, and then the second line. A flexible dimension, comprising two projection lines, the dimension line (actually an arc) and text outline is drawn.
The two lines picked can create four angles, depending on the direction required. By rotating the cursor the four possible angles will be displayed. Pick the position for the dimension.
