CHAPTER 1

Looking at the Work Area
Graph with straight lines between control points compared to graph with spline curves
When you use spline curves, the line won’t travel directly through the control points.
Instead, the points control the shape of the curve. To get the curve closer to a control
point, click to create more control points near the point in question. The more control points
there are clustered together, the closer the spline curve will be to those points.
To use graph controls:
Do any of the following:
• To add a control point to the graph, click in the grid at the location where you want to
place the point.
• To enter the values for a control point numerically, right-click the point to bring up the
edit box, or double-click the graph’s curve.
• To move a point on the graph, drag it to a new location.
• To remove a point from the graph, drag it off the graph.
Note: When the pointer is located over a control point, you’ll see it change from an arrow to
a hand.
