What is the.GHA file type? Every day thousands of users send us information about programs they open different file formats with. At this moment we do not have any description or further details of the GHA file type, but we may be able to recommend some programs that will be able to open such files. Check the list of programs that our users recommend for this type of files below. As we continue to add descriptions of file types every day, information about GHA may become available in the near future. Software to open or convert GHA files It looks like we do not have any suggestions for programs that can open GHA files.

We receive hundreds of suggestions from our users every day, so suggestions for.GHA may become available quite soon.
Summary: Basic information about Grasshopper file format flavors and utilities When it was first released, Grasshopper (then called Explicit History) used the.wrm format. Although the format was extensible and supported versioning, it was difficult – to the point of being impossible – for third party developers to parse. It was also extremely sensitive to corruption since the content was sequential. As of Grasshopper 0.5 and later, the WRM format is now obsolete and it can no longer be written (though.wrm files can still be opened). Instead, Grasshopper data is now stored in.gh or.ghx files. These are, respectively, Binary and XML representations of non-sequential, nested dictionaries.
We have also provided a standalone DotNET assembly which can read and write.gh and.ghx files. Format table. Format Description.ehc Explicit History Components.
This format is obsolete as of version 0.5+.gha Grasshopper Assembly. GHA files define Types, Parameters, Components, and Graph Mappings.wrm Grasshopper Definition File. This format is obsolete as of version 0.5+.ghx Grasshopper Xml. Grasshopper definition file.
This format was introduced in Grasshopper 0.5 and is the default file format.gh Grasshopper Binary. Grasshopper definition file. This format was introduced in Grasshopper 0.5 and is the binary version of the.ghx format. EHC and GHA files.
EHC and GHA files are DotNET dll assemblies which reference the Rhino DotNET SDK and the Grasshopper plug-in. As of Version 0.5, the GHA format superseded the EHC format, though EHC files will still load. These assemblies are parsed using Reflection.
All defined non-abstract types which implement certain interfaces, derive from certain base classes, or adhere to certain rules will be merged into the Grasshopper runtime. At this time, GHA files can contain Components, Parameters, Custom Objects and Graph Mapper definitions. They can of course define as many custom types, dialogs, and resources as needed. These are two new flavors of file format that were first included in Grasshopper 0.5. GHX files are human-readable text files that conform with the XML1.0 specification (at least, I hope they do). GHX files are direct representations of the nested dictionary structure defined by GHIO.dll.
As is typical, the XML flavor can be easily read and adjusted by third party code or even by hand. No schema is available yet, but if you have questions you can always contact the. GH files are binary representations of the exact same dictionary structure. GH and GHX files are completely interchangeable.

Both deserialize to an identical runtime structure. The only difference is that.gh files do not store comments which are present in the dictionary structure. Since the format is not humanly readable, and since comments are never deserialized, this was not deemed a useful feature.
