Block adherence problem on sloped wall blocks

Dear Designbuilder Support,

I have a building made of several floors with a sloped wall. I built it by drawing a several storey high block, cuting off a sloped wall and then dividing it into several floors. DB navigator tree looks fine, but the csv export file shows some roofs and exterior floors in each floor block (with 0º and 180º slopes, respectively, but with strange orientations).
I already tried rebuilding the model, but things remain the same.

Besides the mentioned problems, I noticed that the idf and csv files show the windows in the sloped wall as being from the roof glazing template ("project roof template"), that is, DB understands correctly that it is a sloped wall, since the angle to the horizontal is larger than 70º, but the template used for the windows is from the roof template.

Also the CSV shows orientations for a flat horizontal roof. What is the meaning of this?

Can you help me?
Thank you in advance,

João Pedro

The floors and roofs are caused by the 'link body edge surfaces' used by DB to fully enclose zones where there are blocks adjacent to each other. For more info on these:

http://www.designbuilder.co.uk/helpv1/Content/Surface_Types.htm

You can switch them off by unchecking the 'fully enclose zones' Advanced model option.

We did once have code in DesignBuilder to ensure that link body edge surfaces close to other equivalent surfaces were treated as internal and we will look into finding out why it is not working in current versions.
