To have a floor follow topography Align to Topo.  You’ll be prompted to pick a floor and then a topo and it will add the topo points to the floor to make the floor shape edited.

To use Points from Lines you must place model lines (lines and curves only) and then must be physically located below the topo surface.

The reset region asked for you to pick an existing topo surface in the existing project phase and a new topo surface (usually created as a graded region). You pick a rectangular region in a plan view and topo points within that region are deleted from the new topo surface and new points are copied across from the existing topo surface. This will not reset boundary points.

Families that are joined to other families can also generate errors. A pick edge has been included to allow the topo to be aligned to an individual edge within families or elements.
