I am trying to create a pdf with several 3D models inside a single page. The aim to show only a single 3D model on a designed area, on the basis of the choice of the user (e.g. selecting a different option for each 3D model by means of buttons or dropdown boxes). I tried to work with layers, creating a layer for each 3D model, but when I import them, Acrobat converts the 3D contents in 2D contents (images).
Thanks in advantage and sorry if my English could be bad.
