one - you should be able to draw the wall left to right and then down to make the brick appear on that side.
try starting the wall just a little bit away from the adjacent wall that is already drawn.
You will have to do some adjusting to get them to plane out with each other though.
two - after a wall is drawn, just edit the wall and change the degrees that the wall is drawn at, and double check the display of the exterior surface.
example, if you wall is drawn at 90.0 degrees, then edit your wall and change it to 270.0 degrees.
That should change the direction of the wall. It may put your brick on the opposite side, but that is where you just modify the display of exterior side, by selecting the proper direction.
You will also have to adjust the wall to get it to plane out with the adjacent wall.
three- if you are concerned about 3D, then offsets and wall heights impact the view tremendously.
You may have to draw one wall just for your 3D view in order to get it to look proper, then go back to the two walls for your plan.
You can do this in a variety of ways, but I like to use building options to do this, because when you turn one option on and the other off,
it also disappears in 3D mode.
