Hello,

I have create an sample 3d pdf then i attach a u3d file as resource to pdf level.

I create a button :

c3d = getAnnots3D(0)[0].context3D;

var ressource = new c3d.Resource("pdf://one.u3d");

c3d.scene.addModel(ressource);

c3d.scene.update();

I don t know why it doesn t work.

return :

Line: 0: Code: 1(0x1): addModel

GeneralError: L'opération a échoué.

ScriptProxy.(null):3:Field import_number:Mouse Down

Line: 0: Code: 1(0x1): addModel
