View Full Version : Beginner question: cutting nurb splines

someone showed my how, but I can't duplicate it on my own, and online help is only getting me more lost. I duplicated a curve on a nurbs object, and want to create a boundry surface. In order to do this, I need to cut the curve into 4 sections. I've tried Detach Curves but that is not doing what I want...I just need to divide the curve into 4 sections at the points that I desire.

I know this is a stupid question, but I just can't seem to figure this very basic task out.

ok, I must be doing something wrong...inserting a knot doesn't do anything. I've tried detach curves both with and without inserting knots, and it does the same thing:

I cannot get four curves seperated where I want them. Instead I get several (more than 4) curves that overlap each other. I try zooming in and carefully deleting them, but no matter what I do, the boundary object I create has completely @$!#ed geometry. I cannot believe I'm having so much trouble with such a simple task...no tutorial I can find covers such a basic procedure.

I've tried restarting maya and my machine as well.

i dont think you need to insert a knot.

once you have a curve do this:

with your cursor over the curve, depress RMB and go to Curve Point mode. LMB the red dot to the location you want to cut. when you're done, Edit Curves > Detach Curve.

works here.

you can set multiple curve points by just shift LMB with Curve Point turned on, just in case you didnt know.

thanks so much! I knew it had to be something very simple...just missing that vital mundane detail.
