sloping roof error

Hi All,****

** **

I am modeling a building with sloping roof (all gable ends). Equest has
generated a pitched roof where the ridges don't match (at one intersection)
in plan as well as in their heights. I am getting following error while
equest is calculating pitched roof intersections and planes:****

** **

?Error 10: Not all roof surfaces could be completely generated?. I tried
revising the roof shape but it is not helping.****

** **

I have successfully changed the pitched roof to Gable roof for all the
wings except one (where the ridge has changed its elevation). How do I make
the ridge align with other ridges in plan and in height to make it a gable
end? ****

** **

I am attaching a image with this email.****

Please help.****

1. I would ask your architect if that's really how they want to do their roof. If it was me I would align the ridgelines. That looks terrible, but will also be a nightmare to flash.

2. Is it possible for you to simplify the roof shapes? Thermally there might not be much of a difference.

3. If you really want to model it like that - build it in a 3D interface like Sketchup to study how it will actually go together. This might give you a better idea of how to simplify it.

4. Lastly - if you have access to Revit, you could build this in Revit and export the GBXML file to green building studio to generate your inp file.

Thanks Vikram.

But the actual roof is a simple Gable roof with all the ridge lines
aligned. Equest is building it as pitched roof after I check the sloping
roof option box. I wanted to make that end as simple Gable end with aligned
ridgeline and same height as other ridges. Please find the attached image
of the expected roof plan.

Thanks,
Amruta

Well - then if you built your model correctly, it should look something like this:

Check your geometries. And really - try it out in Sketchup first

Thank you for your email Vikram.

Sorry, But I forgot to mention something that, these are two different
shell components with different building types. The moment I build them
seperately eQuest does not consider the main ridge running continuously and
I have a break in between.
But if this is the only option then I will go ahead and make it one shell
and edit the zone type and schedules manually.

Thank you for your help.
