yes exactly . a minute age I did it again . I drew a closed area on level 7 and copied it on level 6 .
again on level 7 ( i drew , it could recognise the room boundary )but for level 6 that I copied, it can not recognise the room boundary .
please find the attached file.
From floor-to-floor, are you using the standard Copy command or Copy to Clipboard » Paste Aligned to Selected Levels/Current View?
From a section or elevation view, select your datum symbol for Level 6. See its Computational Height parameter. Has it been altered unknowingly? The default computational height is 0. If that value is higher than your interior walls, your rooms will be ignored. Maybe your exterior walls go full height spanning several floors, and that's why they are recognized as boundaries?
the exterior walls go fully up from 1st level up to 9th level .
but for example we want to create rooms on level 6 .
in this situation I choose the exterior walls and limit them to go up up to 7th level . again the problem have not solved.
again I copy the exterior walls to the up levels the same like interior walls . the problem has not been solved
thanks for your reply and guidance.
The floors are placed 11cm over than the level datum . and all of the exterior walls re go up to 10th and the others go up to 14th level .
so the floors and the extrior walls have connection on level datum .
baut the interior walls conneect ech other on 11 cm over the level datum .
and the computation height were defined zero as a default .
so when i change it to 11 cm all of the walls were recognised as room boundary.
