Traditional Bay window Revit Tutorial (updated)

This looks at how you can make a traditional bay window.
This involves a number of process:
Walls and edit wall profile
Curtain wall and creating a new mullion size
model in place extrusions and sweeps for sills and bay corners
Roof and ceiling
Filled and masking regions for touching up
To cover over interior brick faces you could paint the surface.

Please update this tutorial, it freezes between 10:45 to 12:45 whilst you are lecturing on how to construct an opening light, but the commentary continues out of sync. Many thanks in anticipation.
