Hi all,

I am trying to model a tensile roof structure. I have generated the mass surface form. and then when i select roof by face from massing tools, some of the sub faces do not get converted into roofs. what's the issue. Some of the faces convert when i select "faces at the bottom of the Roof" option from properties. But some don't happen in any case. while one of the faces does not get selected at all. 

Posting the images of the mass and roof by face issue below.

The only advantage to roof by face is layers.   If you don't have that, then why use a mass.   The same tools you used as a mass can be used to model in place under the roof catagory.

I HATE MASSES in the project.  They are useful for planning studies and for special walls/roofs that need to be done "by face" but otherwise - model in place, SET IN THE RIGHT CATEGORY, is a far superior approach.

the reason i am using mass is since the 'create form' tool gives the perfect form as required. While modelling via the other route viz. in place roof component, the modelling tools wont give me the same results so easily. In case of in place roof component, the closest tool i can use is 'swept blend'. But it doesnt give me as good results as easily.
