Hi I i need to solve a problem trying to export from rhino to revit with grevit. I have a parametric facade and i need to export to revit. When grevit connects to revit it fail and said this:

"Revit could not complete the external command. Contact the provider for assistance. Information they provided to revit about their identity: MTT"

I have had some success with Grevit. I really like the plug in. What I like about it is that unlike Hummingbird, Which I also like (but unfortunately stopped developing) Grevit elements transfer ALL at once so it is easy to undo the tranfer. Great job. Floors work so well everytime. by the way I didnt quite get how room component works- how come there not no xyz input? and how is it possible to transfer all the rooms on different levels when in revit its only possible to insert rooms on each level from the plan views?

Thanks, Grevit

Can Grevit control any Revit Curtain Wall Compnents such as "Top Constraint" and Vertical Mullion Offset?

Hi Max, 

I am having some issues when transferring adaptive components points into revit. 

It gives me an error for every component. 

Can't make type "FIN 4 point_acr02 : A1".

This is after setting the family name (FIN 4 point_acr02) and the type name (A1) I want to add. 

I have tried creating the types on the Revit family before importing, but the result is the same. 

Any ideas?

Of course, and a lot more. I am currently documenting the code.

Is metric conversion something I can add internally when the project becomes open source?

Comment by maximilian thumfart on June 4, 2014 at 9:04am


you have to scale geometry or values before you send them (*3.28 or sth.). I am not handling it internally yet.

Metric for Grevit.

Hello, how to get grevit to work for the metric system. I am outside of USA and everything is metric here. Should I scale everything I do in Grasshopper before sending to Revit?
