You can access the current Rhino document using the 

 

Rhino.RhinoDoc.ActiveDoc

 

property, which is a static (Shared in VB) property. Note that when Rhino starts or shuts down, there might not be an active document, so you should check this value for null (Nothing in VB).

 

The example you linked to uses the old SDK, Grasshopper uses the new SDK (called RhinoCommon). RhinoCommon documentation can be found online.

Thanks a lot.  So this and the line Michael had given should return the same value I guess?

Had just quickly tested his version there in C# component, seems returns a string with value "m" (mm, km, etc in other cases I suppose).
