Gable Wall Cantilever Underside

Recommended Posts

Trying to add some detail to a gable wall by extending it over a custom bay window structure. Ceiling on 2nd floor is ok, and the framing appears to be decent, but I just can't get the underside of the cantilever/boxing to cover. I've tried many tutorials on cantilevers, but it doesn't seem to apply to this scenario when automating the build. Is this possible, or do I just need to manually create the area? This current version was accomplished by creating a 3rd floor, and adding a new gable end wall. I also increased the overhang length. Thank you.

again,  you should post the plan,  but if I had to guess,  I would of really turned that attic level into a REAL FLOOR WITH  ROOMS,  and then the cantilevered  portion would have a finish defined by you.  If you look at the underside you should see a finish material,  but it will have no thickness,  because of this if you have the framing turned on I  bet you will see z fighting between the framing and the soffit material ....  so the solution would be to turn off framing.

 

Of course you can always add a psolid under the cantilever to serve as the finish.

I believe this article was my guide for the 3rd floor option:

https://www.chiefarchitect.com/support/article/KB-00979/message-you-created-an-object-on-the-attic-floor.html

 

I'm not exactly sure how I create a room in the attic that then allows me to automatically create the framing that creates the floor or 2nd/exterior ceiling for the overhang, since I can't define any rooms in the attic, just walls. I've attached the plan with what I was able to accomplish so far in the attic, but if you could guide me just a little bit further, it would be much appreciated. It could also be that I'm assuming auto-framing will work for this... when it won't.

That is the point of the extra floor.  Attics will never have a room.  So create the extra floor.

 

if left office so I can’t look at your model

You could create an open below room on the 2nd floor. No 3rd floor needed. You will need to verify framing etc.

Works great. I still kept the 3rd floor for auto-framing purposes, but adding divider walls on the 2nd floor and making the space open did the trick. Thanks again.

No worries. Here is the plan with the 3rd floor.

this is how you use the top floor to get a finish at the overhang.  Notice the z fighting?  framing and finish?  turn off the framing and it should look good.

Ok, and this does not require extra members on the plan view. I guess the downside is that you cannot specify a material thickness? 

 

While we're at it. Can you help explain this gap?

Guessing you are referring to the walls used to create the extra rooms.

 

Place them on a new layer and turn that layer display off.

looks like a gap for flooring on the 3rd floor.
