Ronan,

 

When creating Revit models for the purpose of gbXML, develop a separate
model for this specific purpose. Standard punched openings work better
than curtain walls, but check and see if aligning the curtain walls with
the centerline of their "host" wall will help. Always model external
shades as standard roof elements and make sure one edge aligns with the
centerline of the "host wall".  As for the disappearing room-
investigate it very carefully and you will likely find some oddity in
the connections of the bounding elements that is causing the "hiccup".
For all of these reasons- the normal Revit architecture or mechanical
models will usually not work for the purpose of creating valid gbXML.
Test it early and often as you build it up a gbXML optimized Revit
model.  You are fortunate to have full <VE> because you may still have
to make final corrections in it.

 

HTH

Dear all, 

I am currently working on a project where I've to model energy, thermal
and daylight analysis on a very large building. I'm using the link
between Revit MEP2008 and IES. I've also got the full licence for IES's
applications. 

However, when I import the model into IES several issues and problems
occur that I require help with, they are as follows;

1) Some windows disappear. These windows are made up as curtain walls.
Now most of the windows in the model are done the same way but a
particular few disappear, troublesome.

2) External shading devices disappear. These are modelled as a
speciality family. I've tried them previously as windows and they don't
work. I would like to use them as a wall family but due to the
architects 3D modelling procedures and the complexity of the model, we
can't. 

3) One of my rooms is disappearing. Claims it has no bounding elements.
But it has 6 bounding elements (walls, ceiling & floor). 

4) Internal light shelf becomes a "floor" leaving the space reshaped and
obscure. 

 

I'd appreciate any help on the matters and am willing to share my
knowledge to help others. I'm very versed with these issues so please,
don't be cheeky and recommend Autodesk's White Papers on BIM or energy
modelling as I've read them. There is also a detailed discussion about
this on Autodesk's forum
