In your opinion which of these two kind of model works better in Ecotect? I guess they are two differt way to have a simple model to be exported. I am going to keep my background (trees and topographic surface) in dxf because it is shaped as mass object.īefore starting to build the second model I would like to ask one last thing: you talked about a model created by thermal zones (which I created in the model you saw amyway) but I also read that I can create one by mass.

Reading on websites and internet forums I understood that the best thing to do is to semplify the model as you suggested and I am going to do so not to spare any more time and in order to have useful studies. For example it recognizes some of them that go from the floor to the ceiling but not those that rest on the wall (I mean when I have half wall and half window) and I see a wall from top to bottom. I confirm that Revit doesn't recognize curtain wall properly when exporting as gbxml. I have done the same exercise that you are doing with the Farnsworth house which was much simpler to model!

I am currious to know whether your curtain wall appears in the dxf - not once you import it into Ecotect but in a different software that reads dxf? Keep your model very simple, think 'shoe boxes' with windows. That is more time consuming in theory but in practice, too many users spend much time trying to correctly export their Revit model into Ecotect so they have to spend just as much time. It looks like Revit does not recognize the curtain walls when exporting as gbxml can you confirm that in the gbxml export window of Revit prior to the export? If that is indeed the case, you may have to modify your Revit model (or create a new file specific to your thermal modeling export) so that it utilizes regular windows rather than curtain walls objects.Īnother method I have used in the past, is to use a dxf or gbxml file into Ecotect as a background only and recreate only the simple volumes (thermal zones) of your building and location of glazing. For example, make sure that roofs are not made of floor or slab elements etc. In that regard, gbxml does a great job, but there are a few caveheat as you noticed:įor one, you have to be pretty strict with your Revit model.

Instead, you want to simplify your model to simple zones with glass apertures. This is definately not the way to go for any thermal analyses as your model is much too complex for any useful studies - terrain, trees and other very detailed objects will slow down the whole process and not give you much more detailed results.
