Arc 3-Points

Arc 3-Points

Menu:	Draw Arc - Through 3 Points
Shortcut Keys:
Toolbar Icon:

 

The 3-Point Arc command will allow you to draw an arc made up of the starting point, a point along the circumference through which the arc passes and the end point.  A 3-point arc may be drawn in either a clockwise or counter-clockwise direction.  Before drawing an arc, make sure you have chosen the correct layer assignment.

To draw a 3-point arc:

1. Click one time with the left mouse button to set a point for the beginning of the arc.  The Anchor Point will be set at the center location.

2. Move the cursor to a new location.  The angle and distance from the start point will be shown in the Status Bar at the bottom of the screen.  Click to set a second point at the desired radius to begin the arc.
   
   
   Start point 1 and pass through point 2.

3. Click to set the third and final point for the end of the arc pattern.
   
   
   Possible 3-point arcs.

Note:

• Pressing the Esc key before the second point is set will end the command.

• Pressing the Esc key before the third and final point is set will back up one point.

• If the Polar Angle is turned on, the arc will "snap" to preset angles based on the Polar Angle setting.

• The Anchor Point will move to the center location of the arc on the screen.  The distance (radius) and angle from the Anchor Point location is shown in the Status Bar at the bottom of the screen.  The Anchor Point will not move to the second or third point of the arc.  You can manually move the Anchor Point to one of these locations after the arc is drawn on the screen.
