3.9.7.7 Curve Tool: Selecting Linear or Cubic Segments

A curve can consist of a mixture of cubic (curved) and linear intervals. By default each interval is

cubic, but you can freely change an interval's type between Cubic and Linear. Each point controls

the interval that follows it.

Note: Linear intervals are not available in Standard curves. See Standard vs. Enhanced Curves

for details.

Note: It is not recommended to put two or more linear segments in a row because they will

cause an acceleration spike (not displayed in the Curve Tool) at the transition and therefore a

significant jerk in the motion.

To change an interval type:

1. Select the point or points that precede the intervals you want to change, as described in Selecting

Points.

2. On the View menu, click Properties.

You can also double-click on a point, right-click on a point and then click Properties on the

shortcut menu, or press ALT+ENTER or ENTER to open the Point Properties dialog box.

3. Under Advanced, select either Cubic or Linear from the Interval Type list.

4. Click OK.

You can also change a point's interval type in the Spreadsheet view; see Spreadsheet View and

Editing Cells for details.
