Roof planes

[dshall]

Another way of showing where it's off.....In the jpg, the auto generated roof shows the overhang at 18" in one area and 18 13/16" in another. The shaded area needs to move in the -Y direction 13/16". Make sure to align the 2nd floor walls, to the walls you moved below. Then, it auto generates correctly.

Interesting. I wonder how this would change if I had 9' default plate heights at first floor and 8' default plates at second floor
What about 8' default plates at first floor at first floo and 9' defaults at second floor.
What would happen if both first and second floor plate heights were at 8'
What would happen if I had 8' plates at first floor and 16' defaults at second floor....... Would I get two separate roof planes?
What about 9' default plate heights at first floor and 5' default plate heights at second floor? Would the first floor roof cover the second floor roof?

Of course all these questions are assuming auto roofs.

The point is, whenever we explore the behaviors of CA, sometimes it is helpful to take it to extremes to fully understand what is going on.
