You have a large Revit model that you wish to import into Ecotect Analysis and would like to know how to simplify the .dxf file and the gbXML file.
Using the Visibility / Graphic Overrides menu in Revit you can make invisible / turn off elements that are unnecessary in Ecotect Analysis. This will reduce the complexity and size of your .dxf export and make the model easier to manipulate in Ecotect Analysis.
It is recommended that you simplify your Revit model for all analyses that use .gbxml export.
Keep in mind that Ecotect Analysis is a design tool that is meant to be used in the schematic phase of a project when feedback from the tool will enable the designer to make decisions about orientation, floor plate depth, massing, etc. During this phase, the BIM model is expected to be really simple, almost like a massing model but with some internal partitions that denote zones for air-conditioning or daylighting. By the time the project is in Design Development, the BIM model has a lot of extra information that is not needed for sustainable design analyses and makes analyses unnecessarily complicated. The additional information in the model does not add to the accuracy of the analysis.
