is it possible to draw dimensions on 3D view in ArchiCAD 7.0?
Not without a custom GDL object (or custom API programming). There is one at objects online that I just found - had a memory of seeing it once:
which may be as good as it gets for 7.0. (The 3D 'dimensions' from such a GDL object are not associative ... they will just be snapped to available hotspots in the 3D window, and if the underlying objects change, the 3D lines and text will just remain where they were.)
For 8.1 and 9.0, such an object should have editable hotspots to make it easy to readjust the dimensions; the page at objectsonline makes it sound like this particular object has not been updated with the 8.0 and above editable hotspots. If anyone knows Steve Campbell (author of this part), you might ask him to post a comment to this thread.
