Prosteel Animation

Hi, I have created the frame of a structure using shapes generated by Prosteel (I-beams, tubes, plates, etc.) and would like to animate parts of it. I have tried using the animate tools but they do not recognize the Prosteel items. I can create solids using the Microstation tools and then get them to animate, but when I try to select a shape I created with Prosteel it won't recognize the part.

Is there a way to animate Prosteel generated shapes?

Thank you,
-Dave
