Introduction to Maya - Modeling Fundamentals Vol 1
This course will look at the fundamentals of modeling in Maya with an emphasis on creating good topology. We'll look at what makes a good model in Maya and why objects are modeled in the way they are.

Problems offseting and filleting curves
I am currently learning basic NURBS modeling and the tutorial I'm on (cutting and filleting curves) calls for me to make a curve, which I've done, and then use "Offset Curve on Surface". Nothing happens when I try, and that's my first problem.
I circumvent this roadblock by simply using "Offset Curve" instead, which seems to yeild the desired effect. I get a curve parallel to the first. Next, I add a strait line on top intersecting both and snip the ends off, making all of the edges flush. Now I'm supposed to fillet the top left corner, but nothing happens. This is the biggest problem.
FAQ's, Maya's built in help system and the book are no help, and this looks to be the best forum I've yet seen, but a search gave me no useful information. I'm hoping someone here can tell me what Maya, the book or myself is doing wrong.
I made sure that all of the curves were going the right direction and followed the book's directions to a T, but it still does nothing. If I can clarify anything further, or you'd like pictures, I can do that.
Your experience, help and time are very much appreciated. Thanks in advance.

That didn't work either, and I even tried reinstalling Maya. Thanks for the quick reply, though.Originally posted by Peltra
Maybe go to the option box, and then select edit>reset settings. then click on offset curve on surface in that window.
I thought I should also mention I've already tried changing the radius settings in the Filllet's options.

No luck. I started the project from scratch and deleted history once before offsetting and once before filleting.
Is it possible the Maya 6.0 PLE is buggy? Has anyone else had this problem?

This will be word for word out of the book. The object is going to end up as a teapot.
* denotes possible solutions I've already tried. I may have done them wrong though, but I don't see how I could.
1) Use the CV Curve tool or EP Curve tool to create a curve that resembles the profile of a teacup. Start at the origin and move up. See the illustration shown here for help.
[Since it'd be too hard to give you the illustration, here's the coordinates it gives, if you want them: (0,0) (-2,0) (-3,1) (-4,3) (-4,6) ]
2) Choose Edit Curve | Offset | Offset Curve On Surface. This will create a parallel curve.
3) At the top end of the curves, use the EP Curve tool to create another curve that intersects both of the profile curves, as shown in the following illustration.
4) WIth both curves selected, choose Edit Curves | Cut Curves. The intersecting curves will be cut into multiple peices. At this point, you could select any two of these curves and use the Attach Curves tool to connect or blend them.
[Here there is a paragraph which is saying why we're using the Fillet command instead of the Blend Attatchment Method. ]
1) Choose two of the resulting curve segments and delete the pieces of the new curve that extend beyond the intersections of the existing two curves, so that you hvae something that resembles this example: (illustration )
2) Before using the Fillet tool to create a round corner where these curves meet, it is important that you check the direction of the curves.* Maya will attempt to create the new curve in the angle of the U direction. For this reason, you may need to select one or both curves and choose Edit Curves | Reverse Curve Direction. Firgure 3-23 shows the curves before and after the fillet has been created. Notice the direction of the curves in the image on the right.
3) Now select both curves, and choose Edit Curves | Curve Fillet (options)
4) In the Curve Fillet Options window, reset the tool's settings to use the defaults and click Apply. You should see a new circular curve that transitions between the two existing curves.
5) If the operation failed, it is either because the curves were going in the wrong direction or the radius attribute in the Fillet tool options was set too large. Undo the fillet operation and try decreasing the size of the radius.*

) see attached for file:I have a strange feeling this is not the softwares fault.
