In one file I have successfully split a solid. I then go to an earlier version of the solid and try the split. Everything appears to go fine as there is no fail message. But when I try to select only one half, I can only obtain both halves. It is as if they did not split.
If I try to repeat the split, I can now select only one half, but the process then the split process fails.
Any idea of what is going on?
