Ripples on a pond Approach:
I first started with trying to make a grid of points using integer sliders for the X and Y axis and also the spacing between points. Next, I made the cylinders using a constant height. That height value was then replaced with a sine value. I used the absolute value of the maximum height of one of the cylinders to offset the base to ensure that no cylinder would have a height of zero. I also added an additional base offset value so the pond could be deeper if desired. Then I imported it back to Revit and fixed the relevant parameters.
I organized my visual code at the end into four subgroups: Variables, Revit, Creating Cylinder, and Color. The color code was for fun to make the pond a cool gradient as you can see in the above picture.
