This option offers a recall of the building heights of your building ensemble (selection).
Start this simple tool from the
building tool context
and
load one floorfile after another via leftclick in the viewport or left/right keys.
This may also be interesting for interactive presentations.......
With some options in the context menu.
Note:
This, of course works only, if any floorfile exists and the loaded floorfile contains the names of at least one of the active buildings.
Floorfiles are generated by the
PLAYGROUND, where every generated iteration of buildings' heights is saved.
