Heating pipe sizing, Project Information

Hi there,

I have inputted all of my emitters and pipes onto the ground floor but just realised I've inputted the wrong floor level height. 

Is there an easy way to change the project information for that floor?

Or is my easiest option to copy the pipework and emitters to another floor that I have not created yet delete the original ground floor and then insert a new DXF file of the ground floor at the right height?

Thanks,

Kieran
