Rebuild Surfaces tool - am I doing something wrong??

Posted: September 25, 2009
Hi I'm an animator who specializes in 2D animation and have recently been studying up on 3D to add to my skills.

I would say I still have my maya training wheels on.

Anyway, here is my problem. I am following a tutorial, and at this point I am modeling using a NURBS cylinder. I create the cylinder, do some minor tweaks with it's shape. Now, when I need to add more geometry to do the more complicated shaping, I go to "rebuild surface", reset the tool to the default, the set "# of spans U" to 20 and "# of spans V" to 20.

After I apply this tool, I can select the shape and right click to "control vertex". at this point I can see every vertex, and I can select them, but none of the translation tools will affect them; they are essentially locked in place.

when I undo the "rebuild surface", the added spans do go away, but still I am not able to move any of the original vertices. only when I quit Maya and reopen my file am I able to go back to shaping by controling the vertices. However I'm stuck because the minute I hit "Rebuild Surfaces" this whole thing starts right over again.

Is this some kind of bug? or am I somehow activating some kind of locking mechanism that I dont know about?

Any help would be greatly appreciated.

What version of Maya are you using?

Seems to me that you are fighting with the technical side and not really "feeling the flow" using NURBS, I suggest you use polygon modeling for a start Smile
