graph3D Control level (NOT VALID DESCRIPTOR)

[Bouyakaz]

Hello,

I don't want to lose some time so I prefer to post again. So, I wonder if it was possible to control the different levels in a 3D graph and to attribute them value. I see in example that it was possible and try to insert it in my code but I have an error.

A pop-up appears "Not valid descriptor". I don't know what this error refer to so if you have any ideas, it could be very helpful.

Thanks.

I try to use fonction like ContoursSetLevels, ContoursGetLevelList ...

What i search to do is to attribute color and value to each level. So i wanted to attribute to each level a value that i've put in a numeric box. I don't see how to chose the first level, and the second, and the third etc ...  that i wanted to configure. In help, they said that a vector specifies each contour level in the plot so I search in this way but it's not easy.
