Hans,
I see what you mean.
The 2D plan and the 3D view are managed and evolved differently although they share a few common things like a preferred minimum size of 10x10 meters for empty homes.
In the very first versions of Sweet Home 3D the size of the scroll bars around the the 2D plan were always computed according to the contents of the plan. But this wasn't working correctly in some cases, and I changed this behavior to let the 2D plan size only grow (except when it's reopened). Maybe I should review that but I don't feel it's so disturbing.
As for the 3D view, I changed its behavior in Aerial view mode in version 3.0, because it was really weird sometimes. Now the behavior is this one: imagine the bounding box that contains everything in the 3D view, then take the minimum half sphere that will contain this bounding box. The Aerial view mode will let you navigate anywhere between a 10% larger half sphere and a 5 times larger sphere. Every time you add, remove or move some objects in your home, the bounding box is computed again and the view point is possibly moved if the distance to the home is too close or too far.
Finally, there are an additional condition: as soon as the home contains some walls or if it's empty (no wall, no room and no furniture), the aforementioned bounding box will be 10x10 meters wide at minimum. This avoids too much auto zoom during the initial drawing of walls (normally the main goal of Sweet Home 3D
), but lets you see smalls 3D models from very close if you don't draw any wall though.I hope this will be clearer for you and you'll finally like it.
I'm open to any proposal to improve the Aerial view mode again, but please keep in mind that it must stay simple.
