An AREAL3d-building contains following elements
level 0 skp-group = building
level 1 sub-group 'facade'
level 2 sub-group vertical
level 2 sub-group roof

facade-details
level 1 sub-group(s) 'floors' (can be components per user default, still experimental)
level 1 sub-group 'block' (separate layer / for block-display)
At the moment we implement more functions / parameters for some basic details like
- columns, inside along the facade
- facade-details with options for vertical and horizontal profiles
- suspended ceiling following the outside contour of the facade/floor
- roof overhang following the outside contour of the facade/floor
Some content is split to different layers, so you can filter, what you display.
