noxx,

as for sh3d, you can only add measurements in 2D for the top-view, there is no solution for adding those for the vertical axis. this would require a side/front view.
sh3d is used to be a "Möbelschubser" (long time ago), with an excellent(and growing) surrounding design engine (thanx for that).

so, if you need a "real" installation software, get eplan, or acad, or whatever.

p.s.: if you consider revealling your home as Germany, you might get answers in the "foreign language" chapters of this forum in your natives...
