Hi, thanks for reading! (This is for a head model)

I am having trouble figuring out how to make a patch out of certain curves that I have created. I would use the "Boundary" function when I create a four sided patch/curve, but in some areas of my curve layout there are curves that don't share common endpoints. This requires me to select five curves to use the "boundary".. I tried using "square" once and it worked, but that was a while ago and I can't get it to work again... I hope I am making sense!
I tried to intersect the two curves that didn't share common endpoints and then try both boundary and square functions.. boundary gives me a twisted patch and square gives me an error saying: the first and last curves do not intersect. After that I intersected all of the curves and it gave me the same warning. Any help would be greatly appreciated - Brian

Fou Boundary the maximum number of curves is 4. Make sure that when you create the curves you do the following.
1) Create the first curve
2) Press "y" to select last tool
3) Keep the "c" key pressend while you place the first point of the second curve. Click on the FIRST curve so the point snaps to it. Place it on the very end of the first curve ("c" still pressed). See how the point being placed slides on the other curve... Let it slide to the end. Now release the "c" snap key and place the rest of the points freely.
4) Do this at all the curve beginings and also on the end of the last curve, to snap it to the start of the first curve.
All the curves intersect, but are different curves.
5) Select the curves and select Boundary.

Ok, so I guess my problem is in my curve layout then. I need to make every curve connect at the enpoint of another curve.
Thanks for the help, I have been trying to learn how to patch model for a while and all of these little issues have been a thorn in my side! :)
