Grasshopper Class to call definition files properties?

David,Is there a class to call up the Document Properties? For example the definition file name? i.e. MyFile.ghOr further the text that can be entered into the 'Description' section of the Definition under the Menu/Window/Document Properties? I can't seem to see it in the SDK documentation.Something similar to the following that would return information about the current file: Dim doc As RhinoDoc = RhinoDoc.ActiveDoc...Thanks,/mSee More

There are only surfaces on the layer in the Rhino file.arrSurfaces is working correctly and reporting all the Rhino.DocObjects.BrepObject (*Notably on {0;0} I feel…See More
