easy modeling issue causing trouble
trying to accomplish a simple task thats causing me a bit of hangups.
so what i want is a shape created from a cylinder. the first pictures gives you an idea of what the shape is (curve projected in RHINO).
now, i want to make this shape in polys. (the final shape should have a thickness, just like a tube).
but i went ahead and tried a couple of different strategies with nurbs intending to convert to polys since that seemed the most straightforward.
1. i have the precise curve i want, so i tried projecting it in maya, and it gave me all sorts of issues like not being able to trim. i think this was because i was projecting a curve that would surround the surface completely by ensuring my curve was = to the diameter of cylinder and this was causing trouble the curve on surface or something...
after trying some other workarounds, i concluded that nurbs in this case was probably not worth it.... unless anyone knows what im doing wrong. again, such an easy task causing issues.
so on to polys..
2. the only way i can think to create this in polys is to create a cylinder with many vertical segments, and drag the CV's to align with the reference curve in a side view.
is this the only / best way to do it in polys?
and if so, is it correct for me to say that working with poly's will most of the time involve aligning things to a reference curve / image instead of having the precision of nurbs and things like projecting exact curve on the surface......
hope to get clear on this,
thanks!

I was not sure what I could do so I tryed project curve on surface tool this worked ( on a nurb cylinder), you need to do this from a side or top view not perspective...............dave
PS. sorry just leave a curve on the cylinder what use is that?

i was projecting from a side view. i'm projecting so that i can trim....
thats where i'm getting the problems.... it won't trim for some reason

Doing it all in nurbs within maya works; however, nurbs tools in maya are finicky. You can achieve a nice result though.
Converting it to polygons is trickery and has a lot of steps - each of which can cause problems if not done correctly. But in the end you can get a poly surface which you cannot get in Rhno since it's an all nurbs based modeling package.
Here is an outline of the process and some renders...Is this what you are trying to achieve?
Let me know if this all makes sense. If you are really confused I can try to make a camtasia video of the process for you.
Here is a similar thread on using booleans and surfaces to create a womans shoe...

i didn't consider booleans because i've run into a heck of a lot of issues with them.
i never know when is an appropriate time or not. in general, i've heard best to stay away from them.
but yeah, i guess there are a lot of steps requiring a careful eye.
so after these suggestions i realized that my starting point will have to be a little bit different. attached are some images of the physical model.
i won't be able to start with a pipe since the top surface will be enclosed......
any ideas?

I will toss together something for you and upload the .obj.
Starting with a pipe will still work. I will just close off the top afterwards

and here is the .obj file so you have a starting point. It contains the final object and all the master objects used to slice it up so you can make changes as needed. Best of luck.
Let me know if you have trouble figuring any of it out.
