I brought a model over to 2024 from 23 and I cannot access the modifier in a basic floor/ceiling slab. In 2023 the modifier is a simple stair cutout made using clip surface.
I enter the 'edit modifier' as usual through several VW versions,but the modifier only manifests as a dotted line and I can't touch it.
All other modifier choices are working--reshape, boundary, edge offsets, etc.
