Some of the results of learning maya NURBS for some time, and is willing to share with you together. This exercise is what I see from the other industrial design forum, is to use Rhino to do, I just followed the idea of ​​making it, move it to the maya.
First make a cylinder, pay attention to set parameters.

\



Move and zoom, as shown.

\

The lower part of the cylinder removed, and the upper part is divided into four parts along the line ISO.

\

Replication.

\



Select two ISO lines.

\

Fillet surfaces generated by surface.

\

Click to enlarge



Copy on the surface of the three major ISO lines.

\

Click to enlarge

Rebuild what curve, attention Number of spans must be set to 3, will produce six control points on this curve, because each end of the curve requires three control points to achieve curvature continuity with the adjacent surfaces.

\

Click to enlarge





The curve with the adjacent surfaces maintain curvature continuity.

\

Click to enlarge

Loft curve and surface reconstruction, making the surface there is an ISO middle line.

\

Click to enlarge

The middle of drawing a straight line.

\

Click to enlarge

Over the top of the cylinder to the middle of the line to do a straight line, be sure to maintain the level.

\

Click to enlarge










Operation is shown.

\

Click to enlarge

Do a straight line.

\

Click to enlarge



Rebuild it, pay attention to the value of 3 Number of spans.

\

Click to enlarge

Settings shown.

\

Click to enlarge







Operation is shown.

\

Click to enlarge

Separation fillet surfaces.

\

Click to enlarge

Operation is shown.

\

Click to enlarge

Copy the ISO cable.

\

Click to enlarge









After a good match curvature loft.

\

Click to enlarge

Render it.

\

Click to enlarge

Poorly, delete the rest, and open the property sheet.

\

Click to enlarge

Operation is shown.

\

Click to enlarge








Render once again found the picture still flawed.

\

Click to enlarge

Select more ISO lines on the surface, and copy and rebuild.

\

Click to enlarge



Loft look.

\

Click to enlarge

This effect is much better.

\

Click to enlarge







Replication of the rest.

\

Click to enlarge

Copy the portion of phase at the original part did not reach curvature continuity, we have to adjust the control points.

\

Click to enlarge



These Y-axis coordinates of the control points to the first row of the same, i.e. 1.5.

\

Click to enlarge

These points, too, do not modify the three points, they want to maintain continuity with the surface curvature next.

\

Click to enlarge







And then render it, seems good enough.

\

Click to enlarge

Then open the attribute table, and select all the surfaces.

\

Click to enlarge

Copy the lower half.

\

Click to enlarge

Re-rendering, a perfect curvature continuity.

\




Forming on a single material.]
