So in Rhino, I've got the file ladybug-sunpath.3dm open and in Grasshopper, I've got the file 0080-ladybug-sunpath-setup-finished.gh. So let's take a look here in Grasshopper at our analysis period. So remember, this is the range of dates and times that we're telling Ladybug to pull sunlight positions from and right now this is set to August 21st from one p.m. to four p.m., so that's the range of time we're going to be looking at. Let's go back to the end of our algorithm and let's just add a step here and we'd like to analyze the sunlight hours during the analysis period. Okay, so that's just a nice reminder of what it is we're actually trying to accomplish here. So before we go any further, I'm going to come back to my SunPath component. I just want to right-click and disable the…
