the project will be more professional if you cross-fade between separate animated clips and then stop at quality stills, because ArchiCAD fly-throughs are rudimentary - they do not smoothly accelerate or pause smoothly. Your best bet is a sort-of hand-off between sequences done in a video editor.
The fly-through tool is still stuck in the first-person-shoot-em-up style.
Remember that most viewers will be disturbed by an animation - for explaining space, calm, paced serenity is best.
