Expected Behaviour

You should be able to see the object composition of a stream.

Actual Behaviour

Right now, if you receive in Rhino/Revit a stream that has just numbers/strings/booleans/vectors/etc - objects w/o a geometrical manifestation - you just get an empty view, causing confusion: "Where's the stuff?". There's no way to answer that question at the moment!

Reproduction Steps & System Config (win, osx, web, etc.)

Receive in the Rhino panel a stream coming from grasshopper with just numbers.
