Welcome to TG Rosie. Not sure what you really want to do
Animated text in a circular pattern?
I'll look and see if I can figure anything out.
Xara 3D is somewhat limited although I have seen one member in particular do things with the program I would have thought impossible.
I one time made a circular outline with several stars rotating round like you want. Don't remember if it was done using X3D alone or not.
My screen saver is a lot like you want, (but not really) It was made using a couple different Xara programs.X3d and (don't remember which version) Xara Xtreme.
When I get to mt main computer I'll find a couple examples for you.
