Floor sheathing

Hi Team,

 

I'm new to the Home Design software and while I've generally progressed quite well with the design I'm working on, there is one element I can't nut out.

 

I'm trying to get the floor sheathing (OSB) to go under the wall framing and come through to the outside edge of the Floor joists/trusses.

 

 

It is important for me as the plan set I will submit to the Local Authority for approval will need to show this in the cross-sections I will create in the wall framing, floor framing and floor sheathing area.

 

Is there a setting to do this?  I just can't find it.

 

Look forward to the expert advice to help me with this.

 

Regards...

The subfloor is already doing that. Look closer 

Apologies. That's an illustration taken from the one of the tutorials, meant to illustrate what I'm wanting to achieve.

Here's how it looks for me at the moment.

heck that looks like the flooring on top of the floor truss since cabinet sit on it as does baseboard molding.

 

check your default settings for Framing.

Fr Foundation, 1st & 2nd flooring as it applies - review "FLOOR STRUCTURE FOR FLOOR X"

Where X is for the floor above E.g. for Foundation tab you set the flooring structure for the 1st floor

My version of CA is House Designer Pro 2025 X16
It's taking a bit, but I am making some progress...
Here's my settings for floor 2.  The typical floor height is 2400mm (8ft) in NZ for a room and so that is my goal for the finished height when all the linings and sheathing are in place.
However, It doesn't seem to matter what measures I change, none of them promote the sheathing to go under the framing (the standard method for framing here).  Here's my settings and a close up of the prototype in the default settings dialogue for Floor 2....

It's either home designer 2025, or chief architect x16. Two different products. Anyway, from your settings for the floor, where default is not checked, there was something changed along the way. 

I'm 4 weeks into the product. So what am I looking for?  Cheers...

Have you spent any time reading the reference manual,  or looking at the knowledge base?

Hi Rookie, Yeah, heaps.  At this stage, after watching and reading volumes, much of the content skims the topics.  The reference manual tells me what it is, but not how to think about it in the application of the design. I'm finding the thinking about the relationship between the floors contrary, but I'm sure it would all make sense with a full explanation.
What I've been looking for (but haven't found yet) is a step by step walk through explaining the logic behind the default “Structure” set-up.  That would hit it home and I'd be avoiding what are likely to be things I shouldn't be doing.  Do you know of such a tutorial I can watch or read...

Most obliged,..

not sure where you got your screen from but here is what I see using HD PRO 2025

 

Framing page is what you see under :

EDIT

   - DEFAULT SETTINGS

           - FRAMING

 1678097177_defualtframingpage.thumb.jpg.437cd6e7d8f6c74837d781d243380f00.jpg

 

Notice it came up on FOUNDATION tab and you can define the first floor structure.

IGNORE actual timber sies as they are program defaults

 

So I then click on EDIT net to FLOOR STRUCTURE

1921816337_FloorStructureDefinition.thumb.jpg.b38e33e1d46970c6cbbfdb3f9b908d84.jpg

 

See it has plywood and JOIST material 11 7/8" tall.

 

that is it. my guess is you do not have the sheathing

 

GEt to that screen and click HELP

Hi Y-G-M-N.  Thank you for taking the time to look at my issue.  That is what I needed to know and it make sense how the program handles floor diaphragms.

I'm back in the race and making progress again.

Most obliged...
