Yes.

2 types thereof:
- an element of an object. Which means a point which is snapped on a 1D object such as a curve, line, circle, arc, polygon...
- an element by itself, which is nothing more than a variable by another name...

Then you use these elements in the definition of an object, such as a curve. For example if your element is of the variable type, you could create a curve which is SIN(x*GA) where GA is the element...

Then, long hold on the A in the plot window, it will become a slider that you can manipulate, click on the edit menu button and you can set min, max, step and the animation type.
animation is the important part there. back and forth means that it will oscilate, growing from min to max and then decreasing from max to min indefinitely. loop means from min to max again and again and again...
you can set the animation speed and if there is a pause when reaching mins/maxes...


Once that is set, a variabe type element will be just like a number that varies with time. A point of element will be a point moving on it's constraining object.

You can define curves that are based on 1 or more elements which vary at various speeds to get nice effects....

That is prety much it...
