Block Edit Project Deleted

editing a block in layout get this message and the entire project is deleted…

“The block was not modified, it must contain at least one object.”


I am not seeing editing a block via a layout detail cause this but I am familiar with the message you mentioned seeing. It is also seen here but only if I were to delate all the objects in a block while editing it and then tried to apply that change. Post a 3dm and the steps to reproduce what you’re seeing please if you need more help. Also indicate the version of Rhino for Mac you are using, I used Rhino 6.30 for Mac.
