Chains direction

The Chains Direction dialog box enables you to determine the direction of the chain. 

Closed chains direction

This option enables you to determine the direction of closed chains.

External chains direction:

External chains are the outer borders of a pocket. You can determine if you want the chain to go clockwise or counterclockwise by choosing CCW or CW.

Internal chains opposite:

Internal chains are located within the boundaries of external chains. By selecting this check box, you can have the internal chains go in the direction opposite to that of the external chains.

Open chains direction

This option enables you to determine the direction of open chains.

• To center: the chain start point is the end of the chain furthest from the given center point.
• From center: the chain start point is the end of the chain closest to the given center point.

Change center position:

Selecting this check box enables you to choose the center position by entering the X- and Y-values or by picking a point on the model.

If you do not change the center position, the CoordSys origin is used as center point.
