extend into Wall (to Core)
When using the Pick Walls tool, there is a setting on the Options Bar called Extend
into wall (to core). By default, when you pick a compound wall with multiple
layers, the floor sketch will extend to the core boundary of the wall. If desired,
you can specify an offset using a positive or negative value. If this option is
unchecked, the floor sketch will use the outer interior or exterior face of the wall.
