or make them all 2x6 and then add ceiling plan in vaulted room to bring ceiling lower than underside of rafters. This does not make sense - is this vaulted room outside Hip wall inline and same ceiling top plate height? Something has to be lower or higher, Not sure how you can have the same top plate height, ridge height, roof pitch, overhang, soffit face height, etc With different roof Rafter lumber sizes. Something has to give as that 7.25" versus 5.5" rafter difference has to be somewhere... PS most rafters are made from 2x10 in my area and supported in attic to keep free span to spec.

so the rafter depth changes in the middle of a room or at the walls? maybe post actual pictures of what you have.

might not be able to in the HD series. Unless try making a landing at the top the sane size as your top step and then the stairs can come off of it... might look right. HD just not setup to build the extra top tread when the top level will suffice... I hate to say it but might be easier in long run to change the way you build them and save some $ on the cost of that last tread

the top step is one down from top floor/landing review all the stair options screen gives you.

maybe use CURVED Walls??

it will show up when you are in the floor plan and on second floor. IF does not show up Go into default settings. PLan settings. CLick show Living Area Label.

look at what you have selected for Post and beam part. Maybe play with those settings.

to adjust roof pitch. Go to 2d floor plan. Select wall where the roof plane starts in the top plate ( bottom of slope) OPen up the edit screen for this wall. Go to structure tab. Adjust roof pitch to what ever you want. DO this for all walls that do not have the default roof pitch IF wall is a gable end then select gable. And as always for me.. After auto roofs is done I may have to adjust the roof planes it generates to what I want.

look like "attic wall" parts from railing. hard to say but turn off auto generate attic walls in default settings for walls. then delete them. if that does not work might need your plan. how did you make loft? 2nd floor right?

Well the white planes are the ceiling below and the gap between this whit surface and bottom of 2nd walls is where Floor structure would be placed. Joists and plywood or such. You may have them turned off. Also you may be looking at this in 3d while on the 1st floor. See what level you are at.

Not sure but probably one where you have to play with things to find the culprit. My guess is they are made on the first floor level not the foundation or level 0.. And I am not sire if that can be fixed...

Did you try making those cuppola as a DORMER?

Can I make suggestion. Since that is just holding up a pretty much flat roof probably an Aluminum cover type there is not much loading on those posts that they require a full footing. You could get by with just the normal 4" slab and aluminum posts bolting to it. If this is supporting the house hip roof then I would change the row of posts into a RAILING WALL with Posts to BEAM and railing set to OPEN so it does not have railings. Choose your posts design, size and spacing. this then creates an outdoor room you can change to PATIO and lower as required and have house roof cover it. It will treat this railing wall as part of the house and then creates proper foundation, and you can have a footer under the entire length if you choose.

Remember 2026 version is subscription based which means yo have to pay every month or year to work on drawings. if you stop paying the program stops working. But yes newer versions can open older version files. Newer versions CANNOT save as older versions so everything a new version opens becomes a new version file.

floor plan? Ceiling height in those rooms that gable side walls include should have done what you want.
