How Does Bulge Factor Function?

Hi guys, in Grasshopper’s “Blend Curve” component there’s this “Bulge Factor” thing. How does it determine the blend? How does it function exactly? Thanks in advance!

Plug the blend curve into a control points component, and you’ll have a better understanding of it. It’s really a matter of how far from the tangency or curvature of your target curves you want the bulge to extend. I use two sliders and usually cap at 0.50 on each. Some occasions where I don’t bulge one of the targets, I will go beyond 0.5. Also, right click the blend crv component and try changing curvature to tangency and vice versa.
