A question came up on the Dynamo forum regarding randomizing panels.
In another post, I have done a few randomization workflows with Curtain Gridlines.
And prior to that a few workflows with coloring panels randomly by percentage.
It has been a while since I have looked at this workflow, so I thought it would be fun to revisit.
Check out the video below for a walkthrough of how to do this.
and feel free to snag the Dynamo graph from here.
