Showing excavated topo

[revituser195]

I need the portion of the topo that is now hidden by the building pad as a separate solid. Before I start a workaround, are there any out of the box solutions, or suggestions you might have?

I need to show (pre-construction phase) the topo as it was before the pad or building was added, but the building and pad are already in the project. Hopefully the excavated chuck of topo would be a separate object so it can be visually controlled separately.

Thanks,
Rob

This is a job for Phases.

Do a search in this Forum under Phases and topography.

Rob,
phases and phase filters + object graphic overrides and Material override if required.
Not perfect and depends on what you expect - for instance you could get the bits of the topo you want to show from earlier and chop off everything else from that entire surface and have the bit you want in its own phase. You could also have both existing and new showing together without the graphic overrides (can't think why you would want this visually though)

Thanks for the replies everyone. I will be giving it a go this afternoon.
