When comparing slab models in which there are different penetrations, a visual comparison is almost impossible (slab colors blend in). Is it possible to set the highlighting of different transmissions, for example, with a different color than the colors of the slabs?

Is there a function to compare IFC models from different programs? For example, a comparison of IFC Revit and IFC Allplan. In a structural office this comparison is very important for us due to the comparison of the actual shape of the building.

Thank you
