The list of dynamics in the example above includes at least one step of each type of 3D dynamic. GraphWorX64 groups actions in a specific sequence, by dynamic, as a way of controlling runtime results. For example, consider what would happen to a rectangle with a Size action and a Rotation action:
If GraphWorX does the size action and then the rotation action, the result would be a rotated rectangle, which is probably what you would expect.
Had the sequence been to rotate and then resize, the resulting shape would be a skewed rectangle, which doesn't represent what the vast majority of users expect to be the result of resize and rotation.
So for the sake of providing predictable results, GraphWorX applies and enforces sequencing, and groups actions together.
The grouping of similar dynamics has another consequence. The Move Up and Move Down buttons move a dynamic action up or down, but only within its own dynamic type.
