Undo convert a model to primitive


Updated by Altair Forum User
How do I undo a model conversion to primitive? I accidentally clicked 'Convert to primitive' and when I clicked undo, the program immediately crashed saying 'Critical error'. It'll be extremely inconvenient for me to recreate this model. I've included the model. A simple 'yes it's possible and here's how' or 'no there is no way' will suffice. TIA
