It imports geometry, materials and constructions. The process doesn’t input data related to systems.

In this example I change construction for glazing. Well, I’m not sure why people do it but maybe since it is easier to customize your model with Honeybee, or visualize the results.įor now I fixed idfImport component so one can import idf file as Honeybee objects, modify the model and run it in Grasshopper and visualize the results. You are right about the gap and I can also see that in the model that you posted on github. This project came out recently that should ease the process of converting xml idf to each other: The one that you can download from GBS does. It is usually supposed to carry the data but in reality it doesn’t! At least output from Revit/Vasari doesn’t include data for constructions. My experience with gbXML hasn’t been that good. Because the numbers of surfaces determines the simulation speed therefore a more zone model is much better. Instead of export a whole detailed model. What I have done more often is importing these simple xml models into GH for running daylight simulations. Is it to get a more accurate result, or to use the benefit of Honeybee and GH’s parametric possibilities? If so, is it needed to have all properties added in Revit? Only the constructions could be nice to have in the import to Honeybee, or? Why would people try to export and import models in GH with all properties? Knowing the settings in Revit is really limited. In fact this is also a issue when running energy simulations within Revit with GBS. In many cases there is a lot of smal air gabs and other strange things in the export.

As seen in the linked video, it only transfer the geometry, no windows or noting: …Ī basic problem when exporting energy models from Revit is that, the models is typical not that good. There is also a connection from CASE, that export Rooms from Revit to GH directly. It is limited to only import the simple energy model geometry. The problem is often the import of the model is not that good. I have tried using Chameleon (a plugin for both Revit and GH), that allow importing gb.xml files exported from Revit.
