Reference to virtual visitors seeing into walls at high elevations. This effect happens, apparently, in tall buildings. In my case also where I have added terrain 20m high at level 0, and raised the structure so level 1 starts at 20m.

I changed the computing of the front clip distance in version 4.4, and made it grow much more slowly while the visitor is still in the building.

Front and back clip distances were changed again in Sweet Home 3D 5.5. I hope this correction will cover more cases.
