Wall foundations prior to use of join geometry Wall foundations after use of join geometry
The Bottom Elevation of structural foundations (footings) is reported in a read-only instance
parameter called Elevation at Bottom. You can then display this value in a view by tagging the
foundation with the Structural Foundation Tag with Elevation tag. It is available from the family
library, under Structural/Annotations.
NOTE The wall foundation is created at the bottom of the selected wall. If the created wall foundation
is beyond the view range of the active view, you will be prompted with a warning. To see the
foundation, you have to either extend the view range for the current view, or open a view that shows
the wall foundation.
