This tool allows you to dimension the angle between any single line entity and an arbitrary line at an angle to the horizontal.
This value must be specified in the Angle spin box. 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.
Pick the entity to be dimensioned. A flexible dimension, comprising two projection lines, the dimension line (actually an arc) and text outline is drawn.
The angle line specified and the entity 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.
