The time blocks represented in the view area of the Dope Sheet are integer value divisions of time; for example, the block at time 2 includes the range of animation information from 2 to 3, excluding information at time 3.

Animated attributes are bounded by solid lines to indicate their extents. The colors of the blocks define the placement of an attribute or group of attributes within the hierarchy of the Dope Sheet.
