# Autocad start drawing away from the Z=0 (non-coplanar)

I'm having an issue when I draw some elements. They are been drawn away from the Z=0, is causing to be non-coplanar with other elements. So, I cannot make fillets or can find crossing points. I don't want to keep flatten them or setting Z=0 manually. Does anyone know how to start drawing in Z=0 by default? Thanks in advance.
