When I do a bonus room I don't include the floor plan in the model...its just there for the dimensions and to show the client, builder, etc the layout of the room.   I just draw a roof over the garage and edit the gable end to have a window.  Took me a while to figure out the best way to do all this when I was first starting, but this made the most sense to me.

i draw the second floor bonus room as it's own drawing.

 

 

don't know what the best way is.  i guess whatever works for you.

 

as far as the roof goes,  have you tried drawing the roof on the garage plan ?

 

we could use a little more information on exactly how are the walls drawn

on the 2nd floor/bonus room.  are they directly above the the garage walls

or are they offset inside of the garage walls ? 

could you upload a 3d to this thread showing how the walls go on the bonus room in relationship

to the garage walls?

 

WBR,

you can email me your "SPD" plans to randy

remind me of the version your using > V-14

 

include your phone number and what country your in.

i have free calling to canada and within the USA.

 

i also have "go-to-meeting" so we can link up our computers

I've had luck putting a truss set onto the garage or wherever and then edit the trusses, and change "properties"- Style to attic trusses.  you can then edit the size of the bonus room area, and the 3D shows up look just like it will be, assuming your using trusses I guess, to make the bonus room.

[Gary Hood]

Using attic trusses is the way to go to ensure you're allowing enough depth to your joists & to align the overhangs. You might need to go to the truss supplier to get a profile of what they will supply.

It sounds like want to show walls at the outside perimeter of the bonus room on the 2nd floor or attic plan. If it is being conventionally framed, I add a floor system the same the same as any 2nd floor, then use a plate above the floor sheathing to reference the roof. If fascias have to align and that raises the heel too much for your application, you can put the plate on a different layer and turn off the visibility, then reference the 1st floor wall when you input the roof.

 

If it is a trussed roof, the component manufacturer can accommodate pretty much any heel height (4 5/8" is usually the minimum). If the attic room has a 2x10 for the floor, the bottom chords can always be reduced outside of the attic room to 2x6 - this may reduce the cost of the truss as well. In cold climate zones, insulation value usually governs the heel height required.

You do realize that you can reference the lower floors walls by choosing "Multiple Floor Roof" while in Roof mode.

That's where I suggested putting the plate on a different layer so you could hide it when you input the roof (essentially the same concept as cutting the wall). You could also set the plate offset on the 2nd floor to the same height as the top plate of the 1st floor wall. Another option is not using a wall/plate at that location on the 2nd floor, you can just use dashed lines to depict the plate on the 2nd floor plan. Just suggesting some other work-arounds.

[Chris Stewart]

Yes that is true. You have to temporarily adjust the second floor wall so that you can reference the first floor walls.

Not the best solution for this case but is sometimes useful for complex roofs where you need to establish a roof plane that is mostly covered by the second floor.

Also it is sometimes necessary to draw walls which are hidden and only used to reference the roof. 

 

I do not know what the benefit of not showing the plate on the second floor plan would be since the actual house will need one. And this produces an accurate plan and material list. 

[Keith Owens]

I'm not sure why you would want to have the plate if the rafters were to sit on the 1st floor wall, other than showing to show the outline of the wall below. I think the best solution for what you are trying to do is to edit the plate definition, and save as another plate called something like "Non-Bearing Plate", and uncheck bearing. Non-bearing walls are not visible in roof mode.

[Chris Stewart]

Well if you have the joists bearing on that wall than the plate will have to sit on the floor. Referencing the wall below would cause the floor joist to stick out. 

 

 

If the joists are not bearing on that wall then there is no need to have a plate there on the second floor.

 

It is a very rare case where you would need to reference a first floor wall which is directly under a second floor wall. 

 

While it is not uncommon to see solid lumber cut to match the outside of the rafters it is not good practice. 

But if that is the intention than there is no need to have a wall there on the second floor.
