Loft floor sticking through roof

It is not an attic. Here is the whole plan. Making it into an attic room will work but then I have to deal with an unfinished sheathing on my ceilings etc.
Obviously there is something I am not telling the program to do, that is what I am trying to figure out.

 

Thank you.

If your structure is as you want it, then you can replace the default floor with a Floor Material Region, and replace the default base with a Room Molding Polyline making adjustments to it so the base does not show on the exterior.

I wonder why my second floor loft flooring is sticking through the roof and can be seen on the outside of the building?

I would just raise your roof plane...even the windows in the dormer are sticking out above the roof plane.  

 

I am curious though as to why the floor finish is building out to the face or the "log" veneer...seems odd.  Maybe someone can answer that.

It would seem at some point you have lowered those Roof Planes ( see Windows too or didn't rebuild the Roof before turning Auto Roof Build Off and have changed some heights? )  The Roof Planes neither sit on the 1st Floor Top Plates or the 2nd Floor's Floor Structure.  Assuming they will be framed on top of the Floor structure they are 5 7/16" LOW  .....  , so you may want to raise them an extra 1 1/2" if you want a 2x6 plate for the Rafters to land on ( yellow in 2nd pic)

No Window issues and no Floor poking through after raising Roof Planes to top of Floor structure.

Yes! This is what I was missing. the windows I knew I was going to have to fix, they were wrong from the beginning but you are right, I was taking a plan with a lower ceiling and raising the ceiling on the main floor without considering that the roof should be raised as well or somehow rebuilt to accommodate the new floor level. I probably would have figured it out eventually but sometimes it helps to get another set of eyes on it.

Thanks for this and thanks everyone else for the thoughts.

Thanks, I was going to fix the windows later, (just sliding them closer together), but for some reason I wanted to keep the roof where it was while raising the ceiling/floor level from where it was on an earlier rendition. But now I can't see a reason for that so you are right, I will just raise the roof.

It looks like you solved your problems for this particular project, but what about those situations where you might actually want the roof lower like that (because they do exist)? 

 

I believe your problems with the floor finish building through are likely because your walls defining that room are being cut down too short by the roof above.  When the walls are cut too short like that, they no longer stop the floor from building through...

Example.thumb.png.29bc48c8aaa45691414232b2217b2476.png

 

so, in order to address this, you can leave your roof planes right where they are and just define a very small attic area in that area where your roof is cutting into the room anyway...

Thanks for the tip Michael, that is a good idea.

Does it fix your Framing issue too ? I am curious...... 

I didn't try that solution as the raised roof seemed to give me what I want and I have not really built framing for this plan yet. Just trying to ge the plan worked out first.
Thanks for the comments.

      hello could someone help me with this roof? Attached is the plan. On the back side (which is bottom side on the plan) I need a 18 feet high shed roof which slopes towards the front 8 feet and there is a loft on the front side. I could get the shed roof, but dont know where should I adjust the height. I am not able to generate the wall for the loft which should come out of the shed roof. File size is big, hence zipped the file

      New to CA Architect 2021. Doing an addition that includes an attic room. I'm having trouble matching the roof and cieling deminsions for that area. It includes a flat and angled cieling plus pony walls that are also exterior walls. See the sketch with finished interior deminsions. Any help is appreciated.

      I am looking for some help on a roof plan I am working on (copying a 2d elevation from an architect) and can't seem to get this to look right! 
      (Also, I don't typically do exterior renderings and thought I would get some practice in - but clearly have no idea what I am doing :))

      I'm stumped....
       
      I am working on a 4-plex on a sloped site so the floor levels of each unit are different. On the left end unit, when I try to change my standard basement floor level from -119 5/8" to -95 5/8" it works in all the 'rooms' but won't stay changed in the 1/2" space between the firring walls and the foundation walls. I've tried changing a firred wall to have no room definition so it included the 1/2" space but then the whole room goes back to the -199 5/8". I've tried everything I can think of and it just won't stay at -95 5/8".
       
      I've moved the footings up to the proper location but as you can see in the .pdf view, the windows are 24" too low and the slab in that 1/2" space is 24" too low. I can't seem to figure out how to get it to appear accurately. I've included the plan file just in case. I'd appreciate any ideas.
       
      Thanks

      I cannot seem to figure out how to make this exposed gable have the same shiplap siding on it that the house has. I built the patio piece by piece using framing members and added roof planes and ceiling planes then added the gable. Now II cannot figure out how to add siding.
