Here are some other tips for using the Smooth Polyline Tool:
- Ensure that your Constraints are turned off
- If you are having problems getting the polyline to ‘curve’ in the direction you want then try changing the Start Angle either by entering in a new angle in the modifier text box or using the tangent tool adjacent to the Start Angle text box
- Create a straight polyline then use the middle grip to create the curve ensuring constraints is turned off
