** Measuring an angle**

Measure an angle when you want to duplicate that angle elsewhere in your model or create plans, such as for a woodworking project. To measure and an angle:

- Select the
**Protractor**tool (). The cursor will change to a protractor, aligned to the red/green plane and with its center point fixed to the cursor. - Place protractor's center at a vertex of the angle (where two lines meet).
- Click to set the vertex of the angle you will measure. The following image shows the protractor being placed at the angle's vertex.

- Move the cursor in a circle until it is touching the start of the angle (one of the lines). The following image shows the first line in the angle (from the vertex out along to the red square).

- Click to set the start of the angle.
- Move the cursor in a circle until it is touching the end of the angle (other line). Notice that the protractor has marks, indicating 15 degree increments, on its edge. The angle will snap to these tick marks when the cursor is close to the protractor while moving around the protractor. Conversely, angle will move in more precise (smaller) increments when your cursor is farther from the center of the protractor while moving around the protractor.Note: Press the
**Esc**key at any point during the operation to start over. - Click to measure angle. The angle's measurement will appear in the Measurements Toolbar. The value displayed in the Measurements Toolbar is referred to as the angular rotation value. The following image shows the second line in the angle (from the vertex out along to the red square). The angle measures 120 degrees.

Note: Set the angle manually by entering a value in the Measurements Toolbar, and pressing

**Enter**(Microsoft Windows) or**Return**(Mac OS X). The value can either be in decimal degrees, such as 34.1, or slope, such as 1:6. This value can be changed any number of times before proceeding to the next command.
