Video Tutorial One: Analysis and Geometry Models
(followed partially with project 1: house model, and also Autodesk data set)
Step1: Open model in Revit
Step 2: Revit File-Export-gbXML
gbXML files export as analysis models. It does not matter what view you export in, it will export the entire model.
Step 3: You have 5 options of complexity to choose from for exporting: Simple, Simple with shading surfaces, complex, complex with shading surfaces, and complex with mullions and shading surfaces. For this I chose complex with shading surfaces.
Step 4: For a geometry model export it as a DXF model. This will only export the one view that you see. This is the other exporting option for Revit to Ecotect, but we will be exporting a gbXML file.
Problems faced: When I tried to export this model as a gbXML model a few errors limited me from exporting. It said, “Revit was unable to identify any rooms. If you are sure that rooms have been created in the project, please check the Project Phase setting to verify that the Project Phase matches the phase in which rooms have been defined in your project.” I tried many things to fix this and could not. For the rest of the work in Ecotect I used their example model to follow the tutorial with. Here is what the program looks like:
How much luck did you have getting Ecotect to recognize your materials? In my experiences I have had to reassign everything. It would be interesting to see some thermal analysis now that you've got it in there. How are those graphs that Ecotect gives you useful?
