I am starting to create a tutorial series specifically geared for the use of freecad for architects and revit users. It's a straight cut-to-the point, know how to do most basic things in 2-hours type of series.
Around 4:00, the wall is not showing but there is a Tick on its icon, you may try Recompute
Turn on the Report View - Wall may give you some hint what is wrong if it is not working / updating
Around 6:00, you mention the windows are not in designed position. You may have just edited the underlying sketch and the Sketch Edge Index / Wall face index change, so end up your windows in wrong location
Around 36:00: Alternative to use Subtraction in the Combo View ...
Double-click the Wall and Task Panel shows up
Go back to Model tab and select the Part Object for subtraction
(Can select on the Model also)
Go back to Task panel and click Subtraction
Then Click +Add, and OK
