Yes as Lev said. Though its pretty easy to add some cool masking effect using FLASH MX. You can get the 2 animations (wireframe, shaded) then u can either use the above mentioned fading techingue or use a masking technuque( make it looks like its getting filled from a point and then after some time the whole thing is filled-looks pretty cool).

After you have done one of the aboce u can export ur movie as an .avi. Just remember to keep all the symbols as graphics (not movie clips) and you will not face problems in exporting.

Though i am a beginner at 3D if you need to know more about the above technique ask any time.
