Hello Anton. The next SP update you could write "transition" script?
For example:

this.transition(hidden/visible, frame_interval)

or between numbers, from 26 to 35:

@num1 = 26
@num2 = 35
@num1 * transition(@num2, frame_interval)

or

3D point

@original_3Dpoint = [43, 10, 16]
@final_3Dpoint = [22, 10, 5].point_transition_to(@original_3Dpoint, frame_interval)

or Vector

@original_3Dvector = [0, 1, 0]
@final_3Dvector = [1, 0, 0].vector_transition_to(@original_3Dvector, frame_interval)

This is very facilitates our job.

Feel free to use the 32-bit version on the Mac - Win x64. One drawback is that it does not show thumbnail images on .skp-files.
