[Equest-users] Roof Error

[Nick Caton]

Hi Pranita, 

 

Sloped roof generation in the wizards fails me more often than not.
Without corrective detailed edit work on the misaligned/missing surfaces
(time consuming), I think your options are either:

1.       Create a custom roof with a simplified perimeter that the
wizards won't choke on (you can see that happening before you even look
at the 3D view), or

2.       Reason whether a flat roof with an unconditioned plenum of
equivalent volume to the attic space and/or an adjusted ceiling height
where vaulted ceilings are present is an acceptable portrayal.  I've
always been quick to caution that eQuest is not an appropriate program
where "aesthetic necessity" has priority over the accuracy of the
modeled behavior.  For sloped-roof buildings, I use this approach more
often than not in eQuest.

 

I believe it was pointed out some time ago on the lists that the
wizard's inability to correctly recognize 90-degree angles and such for
the purpose of generating sloped roofs can sometimes be traced to tiny
rounding errors at the vertices that occur when the building perimeter
is not aligned and square with the x and y axis.  If you are defining
your perimeter in a non-orthogonal fashion, you might find your problem
is solved by using detailed mode instead to define your exact baseline
azimuth orientation.

Hello_

 

Attched is a snap shot of the parts of roofs not generated  in the 3d
geometrty of the building. I am workin in the DD Wizard . the roof is
not custom. Please let me know how to fix this error (snap shot of the
error is also attached int he doc file).

 

Thanks in advance!!
