Please, read the posts carefully and you will find that this "Search, and Find" is not what I wanted! And please stop these catholic-teacher-like-attitude: ArchiCad is as perfect as it is, no need to improve; everything is written, you silly boy, go and find the answer and so on.
Actually I tried the turntool.
It's really not bad, but I had some troubles:
-the arrow key controls did not work;
-the cameras on a path turned into randomly numbered camera positions;
-many options to set, and yet another software to study out the fine settings.
-and after all, it is a simple 3d presentation software, with no editing functions (such as the dimensioning I mentioned before).
So, the original question is still unanswered.
And the exerineces about the conversion to sketchup are welcome.
And I found something else:
google earth connectivity. It's colser but not enough: exports the ge format (kml, kmz). Maybe some converter can be found to convert in between google earth and sketchup (or maybe the newer version of sketchup can deal with the kml files - my skp5 does not).
