Wall angles - Is there a quicker way of achieving this result? At the top of my walls, I want to angle them in and then sit a ceiling on top. To do this, I'm selecting each wall indvidually and extruding a portion upwards then dragging the top face into the room area a bit.

The end result is this:



I have quite a few individual wall sections to do...



I'm sure there must be a better and faster way of doing this. What's a better way to go about it instead of tackling each wall section indvidually?
There are a few ways to do this. My personal choice is to use a curve representing the wall shape as the bevel object for another curve representing the floor plan.


Create a mesh object with the outline of the wall shape you want to use, such as this
Convert it to a curve (ALT-C -> Curve from Mesh)
Create a floor plan and convert it to a curve, such as this
Use the wall shape as the bevel object for the floor plan


You can create the curves directly if you prefer and you can convert the beveled curve to a mesh (ALT-C -> curve to mesh) so that you can modify it.
