Start-Center-End Arc Tool

This Arc Start-Center-End Tool is responsible for creating Arc Entities from a start point (where the arc starts) to an end point (point where the arc ends) about the center point (point where the center would be located should the arc create a full circle).

Creating an Arc (Start-Center-End):

From the Toolbar: Find the Arc Start-Center-End Tool icon on the Entity Toolbar (color coded blue) and Click on the tool. The tool is now active and ready for use.

From the Shortcut Key: The default shortcut key for the point tool is the letter "Shift + A, 2". Simply press the key and the tool will be activated.

From the Command Line: Type "arc_start_center_end" into the command line, at the top of the Notification Window, and press the Enter/Return key.

1. Click on the drawing to specify the start point of the arc.

2. Move the mouse and click to set the center point of an arc that would create a full circle.

3. Move the mouse and click on a point you wish to designate as the arc's end point. By default the arc will be drawn clockwise. If CCW mode is enabled then the arc will be drawn in a counter-clockwise fashion.

Reset:

•	You have just added an arc entity to the drawing using a start point, center point, and end point. The tool has now reset and you can either continue with other tools or add in another arc entity.

•	Using reset (Space Bar) at any time while using this tool cancels all previous steps and restarts the tool.

To add an arc entity using the keyboard using the (Start-Center-End) method open the Tool Tab in the property tree.
