Alvin, you got exactly the effect that I am trying to achieve. I haven't had a lot of time to mess with it today but have just sat down to see what I can do. How long roughly did it take you to do this?
How long? Roughly an hour-plus. I'm not good at this stuff. In addition, I messed with Wall Modifiers and other stuff. And today I am working on a single laptop monitor only; Zooming in and out and moving the camera around takes time. I could do it again in about 20-minutes, especially if I had my large second monitor plugged in.
I used the basic Roof tool, and had to insert 4 of them: 1) The house main-span, including the patio (only able to do that because the patio and house have the same plate-heights); 2) The garage, making it much larger, front-to-back, then it ultimately need to be; 3) The entry, again making it... ; 4) The smaller gable at the Master Bath, also making it...
I'm in Bakersfield, California, you're in Phoenix, Arizona. Our typical smaller not-so-custom houses are very similar; so I get what you're after.
Trouble with this 3D modeling of houses in our markets is: No one wants to pay for the time it takes to produce them. I don't blame them.
I still don't know what the answer is for that other problem: The filling in of the gable-end walls that the Wall Modifier doesn't take care of. If we just draw something
, in Hidden Line Render, we end up with a line where the wall and that something
butt up against each other.
