Is there a way how we can set the UCS elevation to be negative?
Example: Default elevation of UCS is 0,0,0 assuming that 0=Finished floor elevation
Is there a possible way to set the Z to -4'-0? or there is no chance? I am trying to route underground piping and need to know how to do this in AutoCAD MEP.
