unable to open ifc with revit

Hi jon,
I am an engineering student at the university of Bologna. In my graduation thesis I'm working on exporting freeform parametric geometries from grasshopper to revit. I'm using your tools (they are awesome) on GH but I got problems with Revit. When I bake geometries as ifc and try to open them with autodesk revit 2012 I have several error message and nothing appears on screen. I the same problem with the ifc I downloaded from Geometry Gym. I tryied to open the baked ifc with solibri viewer and I didn't get any error, so I think maybe it's a problem with revit 2012. Do you know anything about it?

Hi Michele,

Thanks for the post. Not sure if you saw my recent blog post announcing the fact that I'm developing a Revit addon to import IFC models, it's here at http://geometrygym.blogspot.com I am trying to tie up a couple of issues with this and will hopefully upload a build for users to try. This will take some time to make it as comprehensive as my Rhino import/export, but I will prioritize aspects suggested and requested by users. Can you share an example model or which of my examples relates to what you would like to exchange?

Up until now, most commercial BIM software have developed (and been certified) for coordination IFC models, primarily to overlay and reference. These use only extrusion and faceted brep (mesh) shape representations. IFC viewers such as DDS and Solibri are much better at acknowledging shape representations based on STEP capable of more accurately and efficiently many objects. I am intending on enabling as many of these as possible in Revit. You can of course use my rhino import command to also validate your model data within Rhino.

Hope this makes sense, look forward to other questions, comments and suggestions.
