Specifies the relationship mode that controls how relationships, such as connects, tangency, and dimensions, affect the shape of the curve. You can set the relationship mode to flexible or rigid.

• Flexible mode allows you to use external relationships to control the shape of the curve. For example, you can apply a dimension relationship on the curve and as you make changes to the dimensions, the shape of the curve automatically updates.

  

• Rigid mode does not allow external relationships to control the shape of the curve. Instead, the curve shape remains unchanged and the curve simply rotates.

  

Specifies the number of degrees for the curve. You can specify a number between 2 and 10.

• If you increase the number of degrees the control polygon for the curve changes, but the shape of the curve remains the same.

  

• If you decrease the number of degrees, the control polygon for the curve changes and the curve changes size based on the supplied edit points.
