For Rhino7 it would be use full to have an option in the clippingplane command to add an object. So to make an object the clippingplane. In Vray I use this feature in 3dsmax to clip a part of an interior for example. But in rhino this can only use as a plane. Sometimes you need a to clip it with some corners.
Another suggestion could be to exclude objects from the clippingplane.
What are you’re thoughts about this?
