Attached is a plan with cantilever trusses.
 
Michael mentioned some important information.  In addition to what he said, there are some settings that are interrelated, and determine how the truss will work:
 
The bottom tip of the top chord must not be above the top of the bottom truss, or the cantilever will not generate. Boxed eaves are generally used with the cantilever truss.  The eave sub fascia determines the position on the eave closure panel, so the height of the roof plane must be adjusted with this in mind. The extent of the eave overhang is another factor that must be considered The pitch of the roof is another variable to consider. And as Michael mentioned the roof baseline height above the wall top plate is another important factor. I've included the plan so that you can play with these interrelationships.  All of this can be worked out mathematically, or simply by trial and error.

Check for wall connections, and check for walls with "no room definition" in the wall DBX.

Here it is done as an "old school" geometric construction.
the roofs are set to the angle of the construction, and then curved to the constructed radius.
This is done with auto roofs, so it's real easy, precise, and predictable.

I have the OS and Chief on the C drive, and plan and layout files in the D drive with no problems.

Comments are added in the component dialog area .  Select a window of door and open the component icon, then scroll if necessary to find the comment section, and type anything you need.
 
Another interesting thing about the component dialog is that anything typed into the Code section of the dialog can be brought into the label with a macro.
This is a little known, but somewhat useful feature.  The code section is special in that it is the only area of the component dialog that is accessible in this way.
 
Perhaps of more use to you is that if you save a door to the user Library, you can give it any name you want.

There are a number of ways to take care of this problem; but this is easiest:
 

Here's a different take on the railing over a wall.  It's done entirely with live walls, and live railings.  The method here is to use a double stair.  The stair is copied in place, and then made wider so the copied railing will come up thought the wall, while the original stairway remains in place to show the stringers.  The walls are adjusted in elevation, and then slid into place under the railing.  The method with the railing is to stay just shy of centered under the wall, or the stairs will cut the wall.
 
Having live walls allows the framing to be correct, and having live railings allows me change newel, baluster, and railing stiles easily.  It also allows me to easily edit the run and rise of the stairs as necessary.  I've not shown it here, but this method also allows the stair railing to connect with a mezzanine railing above.
 
The wider stairs that are used to show the railings are set to "back group" so they don't appear to cover the wall layers in plan view.
 
I've attached the plan if anyone wants to have a look.

You'll need to open the DBX of the room above the living room. Under the general tab, select the drop down menu for room type, and select "open below"

It's best to use the "edit area all floors tool" and then Copy/paste/hold position.
 
When you open a new plan to paste into, you'll have to create a blank second floor, and a blank basement, and must set up all of the floor defaults that you used in your original plan.
