Trying to insert a "crooked" isoparm...
 

Hello, people-

Ultra noob here. My problem is this: I have a simple poly plane that I want to crease, or fold, along a slightly diagonal line through it. What I believe I have to do is insert two specially placed CVs along two opposite edges of the plane, creating this "crooked" isoparm. Increasing UV patches only gives me isoparms that are straight up and down. Using a NURBS plane and inserting CVs seems to give me the same result. Thanks very much for any help.

Depending on what you need it for, I'd just use a poly plane.

I'd make it 4 divisions by 4 divisions, giving you 5 vertices in each direction. I'd grab the 3 in the middle on one side and scale them in, till they were about the width of the crease I wanted. Then, I'd select the row of verts in the middle of these 3 rows and move them down a bit, giving depth to the crease. After that, it's just a matter of adjusting them from another angle until you've got the shape of crease you want.

Here, like this -

saw a head modeling tutorial where the plan was to place curvey lines across a poly i couldnt think of a way to do it other than to place intersections at all turning points as above ... but i got the idea that that was not the plan ??? would love to know if there is way as it would empower the process heaps what with puting loops where you want them to startwith etc.

Thanks for the response, guys.

enhzflep- That method is CLOSE to what I was looking for, and I did get some mileage out of it... Creating new vertices - good. Creating new vertices and then shifting or moving them to new locations- bad, as it also shifted the associated textures with it. The tool I was looking for (and found, thank God) is the CUT FACES tool. This allows you to create new lines & vertices on a poly face, allowing you to fold at "crooked" angles, and also not disturbing textures already placed.

Bruce- I'm a noob, for sure, but from all I know about the nature of polys, it doesn't seem like that would be possible- creating a single curved (or even angular) line within a single poly. You would have to create multiple polys and "approximate" your curved path with a series of straight lines through multiple polys. I think....
