Using Revit 2011.

Hope some one can help me with this one, we're pulling our hair out in the office.

Attached shows existing topography with an existing pad (left) and new topography with existing/new pads.  We can't work out why the existing pad is not cutting out the existing topography properly.  Can anyone shed some light on why this is happening?

I have used an existing topography with existing pad, then graded it, and added a new pad.

Play around with the phases, you may want to have an intermediate phase in order for the objects to be in a demolished state. Also when demolishing the first pad it will not remove the altered grade under it you will need to select the altered grade and indicate a demolished phase for it as well. Hope this helps.

revit is great, but topos still are basic.  we find pads are way too clumsy, and phases make them go crazy.  the only thing we find that works is to ALWAYS demolish all existing topo elements, and copy them into the new phase, where we play with everything.  i personally resist pads, and go to the trouble of adjusting the topo, as cut and fill is not easily applied to pads.  the graded command is a super easy way of creating new and demolished versions of a topo, but do not forget the 'copy internal points'.
