To Add Points to Curves
When you add a point to a curve, the curve is refit through the defining points. This sometimes visibly changes the shape of the curve.

2. Click Style > Curve Edit. The Curve Edit tab opens.
3. Click the collector, and select a curve to edit.
4. Right-click the curve and choose one of the following commands:
Add Point—Adds a point at the location selected.
Add Midpoint—Adds a point at the midpoint of the two existing points on each side of the selected location.
