PROBLEMS WITH ALLEGRA AND FOOTPRINTS ORCAD X

Hi,

I am creando a design in ORCAD X, I active the Layout in ORCAD X PCB but I try visualize the model 3D en Allegro, the components are missing in the plate, instead of them, gray cubes appear. I can read the next messages:

Symbol representation is set to: Step Model if available, else the Place_Bound Shape. Symbols without an assigned STEP Model are displayed using the Place_Bound Shape.
