System Category Change

Hi Everyone,

I have Doubt in Revit System Category,
If it’s Possible to Change System Category in Revit Like Roof to Floor.

Please anyone can clarify.

Not that I’m aware of. They are two different Element Types. It would be like trying to change a cat to a dog.

@thiru2jack why do you want to change?

Thank you for your valuable response.

I am Creating Raised Floor by Using Roof (Glazing ), So that i want to change Roof as Floor Category.
