As a new user, I created a Primitive then clicked on Live Clay. Bam! The primitive disappeared. I should have Applied the Primative but this is not the point. It is very bad for software to do this.
1. Is there, in the real world, an actual need to apply the primitive work? Why not just keep it? We can delete work we do not want.
2. if 1. is necessary, a dialog box should appear upon leaving Primitives. It should give the opportunity to Apply or Continue working on the primitives.
The very worst thing a program can do is destroy work.
