As architects I found this software very useful and I think it would be very good if you can incorporate a function to display easily the views of the indoor walls.
Something like this:
We use plans with these lateral views of walls to give instructions to builders about the details of walls, position of lamps, electrical plugs, etc. Maybe you can create a function to get a general view of every walls in a room.
Anyway, thanks for your contribution with this great software.
