I did a little mistake, and here what happened: Try to open
http://www.cgemsformazione.it//3d/classea.html, and then the correct one www.cgemsformazione.it/3d/classea.html

is it normal ?
Thanks

Hello,

We're not sure what your question is in regard to. Is what normal? Does this post pertain to Scene Builder? Does this post pertain to VET? If not, please post your questions in the appropriate forum categories in the future.

I don't know if this is what you are talking about, but the first link you posted contains two slashes (...it//3d/...)
