how to model this shoe in Maya with curves...?
'm looking for tutorials, to create all kind of shoes...
if you known any goodones please let me know it!
i need any help with the following...
i know how to loft, & how i create curves...
but how do i cut meshes with curves?
as you could see in tutorial at link below
can someone explain the steps to do this in Maya...
'm a little bit confused with the extrude & boolian function...

i dont know any universal "shoe making" tutorial, but keep on looking. You will find the answer by urself.'m looking for tutorials, to create all kind of shoes...
You dont cut mesh with curve. You cut patchs(nurbs surface) with curves.but how do i cut meshes with curves?
After selecting a curve and a surface, go to Surface menu set.
Edit NURBS > Project Curve on Surface.
The surface will be cut by the curve.
Then, select the surface again.
Goto Edit NURBS > Trim Tool.
Select the part of the surface(you will see blue point appearing after clicking) which you want to keep and then press enter.
For Boolean:
Create two objects, a circle and a cylinder(whatever), then goto Edit NURBS > Booleans.Test different combination(circle first, cylinder second or cylinder first, circle second) of selection and check what they do.There will be total 6 combinations for 2 object.
I think, you should spend some more time on practicing different tools before actually trying to make something.

Although the tutorial is for modo most of the principles can be applied to maya.

1. Use two of the images from the website at DAZ to create the CV curves.
2. loft 3 nurbs surfaces
3. use boolean difference to cut up the pieces. Delete all history and reverse surface directions where needed.
4. add a 1/4" round fillet where the surfaces meet
I can attach the maya .ma file but it will be in maya 2010 format. .obj will not work for nurbs.
Maya nurbs modeling is not for the faint of heart. They are very finicky. I spent a good deal of time trying to get the surface fillets and had to rebuild the curves several time before maya relented and allowed them to work (lol). No matter how hard I tried I could not get the boolean operation to produce surfaces with the correct surface direction. After rebuilding the surface directions in U and V a zillion times in every combination I could think of I just gave up and deleted history and reversed the resulting surfaces to get what I wanted. Finally if you use Maya nurbs be aware that you will have to spend time analyzing the tessellation of every single surface to ensure you do not get holes or seams.
In short nurbs have pretty much been relegated to creating basic forms that can be converted to polygons and sculpted.
This is sad because I started as a nurbs modeler and for hard surface stuff nurbs give far better control and much higher precision. ALL the high end CAD surfacing apps (like studio tools) are completely nurbs based.
Here are some images to kinda show the steps. The last one is a contour plot showing the 5 surfaces (top, side, bottom, and two fillets). I did not model the straps because I did not have the surface geometry from the DAZ tutorial and they are trivial to model any ways.
*updates:
- added image - used lattice deformer to narrow the heel.

I simply took the boolean of two surfaces to make the top of the sandal shape, then converted it to polygons, and cleaned it up a bit, then extruded the entire thing down, then moved some of the bottom verts to form the bottom, and finally added some bevels and edges.
This is overkill for this object. I could have cut the number of polys significantly but I had the surface geometry so I just went with it (smile).
