Hi Michael and eric,
I'm using Rhino 5.0 WIP 90-day Eval 2010-12-14 (to test RhinoBIM) 64 bit and I have installed also Rhino 4 SR8 eval.
No problem in copy/paste from Rhino5 to Rhino4 or MOI v2 and no problem in copy/paste from MOI or Rhino4 to Rhino 5.
In Rhino5 there is at least a new entity called extrusion (used in RhinoBIM for steel beam members); extrusion is converted in polysurface in copy/paste from RH5 to RH4 and in solid in copy/paste from RH5 to MOI v2.

Hi ..

That is really odd. Yesterday I could not copy/past from R5 into either R4 or MoI and I tried it a number of times.
This morning it is working just fine ... all directions.

I feel like an idiot ... so cancel everything I said about the problem copying files yesterday.

cheers,
eric

Duh!
I discovered my errors of yesterday. I tested the copy/paste functions in R5 by placing a small box in an existing drawing and
then copy/pasting it. When I copy/pasted into MoI it came in way, way off screen and though I did zoom out to find it it just
did not appear to be there.
I tried it again this morning with a developed drawing with many layers. All of them were copied into MoI just fine. Of course I lost
things that MoI does not include such as text, line weights, and line styles. That was fully expected, of course.
I apologize for the confusion and am a little chagrined.
cheers,
eric

No problem eric, and thanks Giovanni for posting your results.

So that's great that making clipboard data available in previous 3DM formats is still working in Rhino v5.
