Revit Pad - Not cutting

[SimonBeau]

There seems to be a few older threads on this but after reading them I am still non the wiser to a solution.

The attached image shows a cut section through part of the model with a 'pad' placed approximately below the building whilst I have been moving it about trying different things.

The toposurface is Existing Phase and Phase demolished - None.

The Pad is Phase 1.

As you can see the toposurface is still above the pad in the model, no matter what phase I put the pad at it doesn't change. I've tried every combination of existing and phases across the surface and pad with no luck.

I've never had this problem with Pads before, anybody shed any light?

Thanks

Simon

I don't think toposurfaces and pads play nice if the phases are different. I tend to have existing topo and proposed topo's and pads. I just did a simple test with a existing topo and a proposed pad. All looks good in the proposed, but the existing has a hole in it where the pad is. It shouldn't be there...

Think it may be related to the different phasing we have but the pad doesn't cut any toposurfaces at all no matter what phase it is set to
