Using Straight Objects

· Use a straight object as a path along which to animate a point by creating the point with the Point On Object command.

· Use a straight object as a path along which to animate an independent point by using the Merge command.

· Use a straight object as a mirror for reflections by choosing the Mark Mirror command.

· Construct a segment’s Midpoint.

· Construct a straight object’s Intersection with any other straight object, circle, or arc.

· Use Define Unit Distance to define a coordinate system with a unit distance defined by one or two selected segments. (The unit of the coordinate system is defined by the length of the segment.)

If you use two selected segments, the first defines the unit for x, and the second for y.
