BOO-YAH!

Fixed ^_^

Rebuild the curve, and then use the tube script.

So, here is the final list of instructions:

1) Select geometry.

2) Use CV curve tool, and use "v" to point snap curve points to every vertex. Snap the last point to the first point, and press enter.

As you do this, COUNT how many points you place. Do NOT count the first/last twice; only once. Mentally call this "number of points."

3) Edit Curves -> Open/Close Curves -> Options. Reset the settings (use defaults)

4) Edit Curves -> Rebuild Curves -> Options. Reset settings. Change "Number of spans" to the number you counted above ("number of points").

5) And now do the createTube script.



Note that I left out "make live;" Maya (7.0) does not allow point snapping on an object that has been made live.
