Dear Jon,

I am trying to import one gbXML file which was exported by Revit .I have  loaded it in Ecotect to apply material. Now, I am planning to import in Rhino to analysis in grasshopper. I have downloaded geometrygym plugin but it does not work in Rhino and just appears in grasshopper. Would you please guide and help me by offering any information how I can to import gbXML files to Rhino.

Yours sincerely,

Hi Jon, thanks for adding, i'm pretty interested about your work and i've been looking around your site some time ago.

i've been using grasshopper only for quiet sometime now, so im still trying to figure out the basic stuff, but i think it would provide such a great help in doing my architectural studies combined with BIM software at hand

has there been any new update about grasshopper and archicad connection?

Thank you

Jon I took a look at your article about Rhino/Grasshopper to Vasari import.

Is there any other way to eliminate the Revit in the process of importing?

Hi Jon!

Thank you for the Geom Gym activation. I´ll be participating in a workshop that maybe will use your software!
