Currently in the Floor Plan Cut Plane Settings we can only set it relative to the current story. I would like to be able to have the choice as we do elsewhere to which Reference Level it is relative to.
Example I have a house with a garage's main floor -34.2" relative to the house's main floor. I needed to set a view's cut plane relative to the garage's floor elevation, not the house's and could not. Instead of archicad doing the math minimizing error, I had to calculate the height of the cut plane relative to the house.
Fortunately my math skills are infinitely better than my spelling
