Protractor

Protractor measures the angle between a point and any two objects in your scene.

The names of the two objects appear above their respective buttons, and the angle formed at the protractor object between the pivot points of the two objects is displayed in the Angle field. Lines are drawn between the protractor and the two selected objects.

NoteThe line to the first selected object uses the Target Line color, and the line for the second selected object uses the color of the protractor. The Target Line color is set with Customize User Interface dialog

You can reselect the protractor at any time, enter the Modify panel, and pick new objects to measure. You can move either of the two objects or the protractor itself to change the angle.

Note

If you need to watch the Angle readout while moving either of the objects, first select the protractor, then click the Pin Stack button on the Modify panel. You can now select and move the other objects while the stack remains pinned to display the protractor angle.
