Commercial building roofs

[Markenbach]

Im making an commercial building and want the typical commercial building roof style (outer wall all the way up, then roof is lower then outside edge)

 

 

I was looking at this method: https://www.chiefarchitect.com/videos/watch/1530/drawing-a-flat-roof-with-center-drain-and-parapet-walls.html

 

but that seemed very complicated for something that should be relatively standard and I had thought there would be a more automatic way of doing this.

There are other ways to do it and probably one of the more easier ways that I have found is create a 2nd (or 3rd if necessary) floor with no roof above set to the height of your parapet walls that you want.  Then change the floor system to be what your roof system will be.  On the main floor you will want to select your exterior walls and set them to hang floor system above on wall (usually with ledger) and the exterior walls above should be set to balloon frame through to floor below.

thanks. I'll give that a shot and try to figure out what all that means!

There are quite a few methods that can be used.  A few things to remember though that will hopefully help you...

• Under normal circumstances and unless they're manually manipulated, walls will automatically build through until they hit a roof or ceiling plane.  This means you can either drag walls up/down in 3D (not the most ideal) or keep your roof planes inside your walls.
• Under normal circumstances, unless they're manually manipulated, and unless they're under a roof or ceiling plane, walls will continue up until they reach the height of your defined ceiling. This means you could set the height of your parapet walls using the room ceiling height or by building roof planes directly over the walls.
• You can create a room's ceiling using a manual ceiling plane and/or by using the room's ceiling definition.  This means your room definition ceiling height could set the parapet wall heights and a manually placed ceiling plane could be used for your actual ceiling. 
• As Ryan already mentioned, you can use multiple floors to further add to your possible options.

There's a newer version of this video (at the same link) you might see if it helps.
