Hi, I've got some basic *noob* questions about working with curves in Houdini, and after searching the manual I've been unable to figure this out. 1) After creating a Curve SOP node interactively in the viewport. How do I add more curve points? I click on the curve and I'm able to move points and delete them, but I can't figure out how to add new ones? 2) How do I define the type of corner for a curve point. Say I want to make the curve in the shape of the letter P, how to I mix curve points
