Angle measurement

Choose the angle tool for one of the 2 mouse buttons. You have to click 3 times to complete the angle measurement: first (1)click to determine end of line 1. Move the mouse to the position where you want the angle to be measured and (2)click for the beginning of line 1 and the beginning of line 2. Now, when you move the mouse pointer, the angle between the lines is displayed. (3)Click a third time to complete the measurement or press 'Escape' to cancel the angle.

An angle measurement can be modified by moving the mouse pointer over either of the 3 points of the angle. The angle will then turn to red and a square will be displayed around the point you moved the pointer over. Drag this square to change the angle measurement.

You can delete an angle measurement by double clicking the red square. All angle measurements can be deleted by pressing 'Delete all measurements' in the toolbar. This will delete the length measurements as well. Go to 'Tools' and 'Delete angles' in the menu, to delete the angles only.

To start a new angle measurement from either end of an old one, move the mouse pointer over either point of the old angle measurement. This will change to red and the square will appear, disabling you to start a new angle measurement. Now simple press 'Escape' to remove the box and red color to enable starting a new angle measurement from this position.

Angle measurements are not displayed when a scene is played.
