Not able to open RV6 file saved as RV5 on R5?

Hi . Saving a file as Rhino 5 in Rhino 6 …not able to open the file in Rhino 5…

Is this a bug? I am a bit confused. I can not load it in KS 7 either…It says there is no geometry.


Hi - can you detail the steps that you take to reproduce this?
Seems like exporting from RH6 to the Rhino 5 file format works fine here.

I selected the model I want to export. Export As (V5). Close R6 and open R5 tried to open the file and says it can not be opened…Want me to send you the file?

Yes, please.

Can you send me a private email ?

You can send that to
