How do I create arcs?

Use the Arc tool in the Sketch menu to draw arcs in your design. Click to add two endpoints of the arc, and then place a third point to finalize the shape. Note that while you're drawing the arc, you can directly type in the radius or angle and press the Return key to finalize the dimensions. To finish the sketch and exit the Arc tool, press the Return key. To remove the arc and exit the tool, then secondary click (right-click) with your mouse or press one of the following: 

• Delete
• Escape

To move the arc, select and reposition the center point. After you finish drawing the arc, you can adjust the size of the arc by: 

• Setting the radius manually
  Just select the dimension label, type in the new value, and press the Return key.
• Using the arrows on the arc
  Select the arc, and pull the arrows on the circumference to reposition the arc.
• Setting the arc degree
  Just select the dimension label, type in the new value, and press the Return key.
