That's pretty much what's in the definition i posted. Although it only uses the referenced line for the wind direction. It uses a slider for the wind strength since i think it's more convenient than having to scale the line in rhino. I should have maybe overlay a line that scales proportionally to it. The reference line is grouped with 2 other lines to create the tip of the arrow.
