Using the Angle Tools

You can use the Angle and Split Angle tools to measure the angle between any two lines. For split angles, Dragonfly will calculate the angle that would exist between the line segments if they were extended far enough to intersect. Measurements are shown with the annotation in 2D and 3D views and are also available in the lower section of the Data Properties and Settings pane, as shown below.

Angle properties and settings

See Annotation Properties and Settings for information about changing the visibility of angles and their assigned color, as well as other options available for annotations.

The measurements and tools available for angles are described in the following table.

Angle measurements and tools

ClosedHow to Adjust an Angle
  1. Select the required angle, either directly in the 2D view or in the top section of the Data Properties and Settings panel.
  2. Click inside the control point you need to adjust and then drag.

    You can also select multiple controls points. For example, if you need to move a side of the angle.

  3. Click inside the selected control point(s) to de-select it.
ClosedHow to Move an Angle
  1. Select the required angle, either directly in the 2D view or in the top section of the Data Properties and Settings panel.
