Framing Elevation & Building Elevation vice versa

Hi all.,

   We can change the interior elevation tool to building elevation tool as follows..,

  To create framing elevation, we should have a grid before creating framing elevation. .

Take interior elevation as follows.
Make sure Attach to Grid is checked in option bar, Then it takes the interior elevation option.

                               

Again take interior elevation as follows.
Make sure Attach to Grid is not checked in option bar, Then it takes the building elevation option automatically without changing to building elevation tool.
