Grasshopper

algorithmic modeling for Rhino

Information

Hummingbird

Hummingbird is a set of Grasshopper components that facilitate the creation of Revit native geometry. This process exports basic geometric properties and parameter data to CSV text files which is used to describe many aspects of the Revit BIM geometry. In Revit this data is easily imported using the Whitefeet Modelbuilder tool (included).

Translating Rhino primative geometry to Revit has been vastly simplified without the need for linking or reference objects. This allows for the downstream Revit model to be modified and adapted for the project duration.

Hi every one,I've noticed that HmmingBird CSV files view it with the CSV viewer, sometimes shows  Item ID's and sometimes does not. Is this an bug or is something I'm doing right. I'm creating panels…Continue

Is there any hummingbird setting that translates everything to imperial system units.

I have everything in meters but the Revit converts from excel enormous values with a conversion factor obviously related to feet and inches

Comment by Manuel Sotomayor Millan on November 5, 2012 at 12:45pm

Just duplicates everything.

Might be an isue because of the file units??

I have both Revit and Rhino set to meters but somehow Revit makes mm from the data that gets from Rhino when imports and again translate meter to milimeters when imports back to Excel. Resulting from that enormous numbers

Might be this the root of the previous problem

Comment by Manuel Sotomayor Millan on November 5, 2012 at 12:42pm

thats right. But once the element Ids are exported from Revit by the ModelBuilder, if I modify the geometry on Rhino and update it to the excel again the elementids get erased, thus the modelbuilder does not identify them back and erase nothing from the revit file

Comment by Mario Guttman on November 5, 2012 at 12:13pm

Manuel. The element ID values are entered by the ModelBuilder tool in Revit when the elements are built. Not all lines in Excel will have an ID value, only the ones that have an 'Add" command. Unfortuanately the ModelBuilder cannot really update them (due to Revit API limitations) but what it can do is delete the element as it creates a new one.
Does this answer your question? If not, please provide a littel more detail on what you are trying to do and what you are seeing.

hi. Thanks you Mario and Tim. Really nice job

I cannot update the geometry in Revit as Hummingbird components do not type the ElementId column in Excell an thus the Revit importer always add new geometry instead of updating.

Any solution to that???

Any suggestions on where to find a good tutorial on using Hummingbird?

Comment by Mario Guttman on October 8, 2012 at 10:27am

If you have had problems linking to Excel try the new versions that I just uploaded to the download site.  This should fix a problem where a US version of Excel was in use on a non-US Windows computer.

Hi Tim,

 

We just downloaded the hummingbird application.  We are try to run some test with the example files given.  When I hit the "button" to publish floors to excel from grasshopper, the parameter becomes red, and rhino crashes.  Any suggestions?

Comment by Mario Guttman on September 27, 2012 at 11:59am

Johan, Sorry about the confusion.  ModelBuilder is a Revit add-in that can work with other applications besides Rhino-Grasshopper.  The "Hummingbird" effort was focused on the Grasshopper components.  We included the ModelBuilder tool with it for completeness.  Sometimes our terminology gets confusing.  Be sure to look at the process diagram on the Hummingbird site: http://ghhummingbird.wordpress.com/2012/07/07/process-overview/

Why would GH give the errormessage then?
