I don't understand your question correctly.
Do u have a VRML file or more of ones?
But I know that first your children of VRMLs must have a name.
I don't access to Labview now.
We can communication with our mail if u want.
Do you have Maltab?
Yes it is possible to rotate a cylindrical by center not corner.
Please send your VRML file and your labview file if it possible.
I will send a file of it has a cylindrical shape.
I will rotate this shape by corner and center separately.
