Hi, If a single curve intersects with itself, I need to divide/split it from where it intersects with carve sop. When I manually enter the value of "sourceprimuv"(intersectionanalysis) to carve FirstU , seems ok.(I don't know how to use attributes procedurally) 1- How do I automatically bind the sourceprimuv value to the carve firstu value? 2- How can I divide/split a single curve if it intersects itself at more than one point? file in attachment. Thanks in advance. intersection.hipnc

Hi, I'm starting learning houdini and really excited. I'm in still learning phase and searching ideas to do. So here is my problem. I have idea for connect two cables with a cable supported collision and simulation result. question 1: can i generate simulation result on parameter change. (i don't need whole simulation frames just need simulation result) question 2: i need generate cable(between two cables ) "according to grid collision" and "affected with gravity". so i'm newbie and just created with "add" sop and seems really bad. wires.hipnc file attached for review. I need advice and/or guidance. Thanks in advance. wires.hipnc
