My model consists of two floors, 2.7m high for first floor and 2.7m for second floor. I added a pitch roof which messed the whole model up, so i deleted the roof data from the DDBROOF.NDX folder along with the ROOFPOLY.* and RLIGHTPOLY.* files. The model has become slightly better, but in 3D model view i can see straight down to the GF- so the GF has no ceiling. How do i add a ceiling to the GF. I also want to add a pitch roof with the middle edge elevated 2.25m, but i cant seem to get the datum height correct. Please can someone help me. im assuming the datum height is just 2.7+2.7=5.4m.
Hi Shane,
Thanks.
Under room data the height of the room shows as 2.7m as shown below:
But the individual wall and partition heights are not showing as 2.7 but are being extended to the roof. In this case is the room height actually 2.7, with a false ceiling?
If i was to go back to global changes and change the ff room heights back to 2.7 but model shows up like this again, and when i do the roof settings as before the wall heights change change.
Shane, is there a number i can ring to get through to you so that i can get a better understanding of the model data.
Hi Aakil,
Everything appears to be set up fine in that case.
