Triple Unit Window Casement & Project with Garage floor

[numberOCD]

I'm new to the Architecture Edition, far more used to 3D in MEP. But I'm trying to finish these architectural plans and cannot figure out how to make a three unit window or triple casement window.

Along with that, I'm still a little puzzled with working floor depths in the case of having a garage at 0'-0" elevation and the main house being 1'-3 1/2" and how I work the walls that have a face on each side of this 15 1/2" drop. I'm also a little puzzled with an 8'-0" ceiling going to a 9'-0" ceiling on the same job.

The F1 is feeling like and FU in the program so any help would be great.

Thanks in advance.

If you know your window mfg, try their website for downloadable dwg files.

 

Two risers +- down from the house to the garage is pretty commonplace.

 

For the "walls that have a face on each side".... There will be a step in the concrete (or whatever the foundation is) between the garage and house. This step will support the garage slab on one side, and be high enough on the house side so the floor framing system depth under the main house plus this step = 1'-3 1/2". So, your wall will be built on top of the floor framing system the same height as the rest of the walls on top of that floor system. Watch out. Garage floors are sloped toward the doors. Make sure your 0'=0" elev. is in the correct spot. I suspect right smack in the garage door opening. This should also be your top of foundation, maybe, probably, might be.

 

Going from 8' to 9'? This is accomplished in one of two ways. First, simply make the walls 12" higher in the 9' part. There will be a step in the ceiling somewhere, probably at a room to room transition. Second, the floor height will change someplace, dropping 12" but leaving the ceiling height unchanged.

Here, I didn't draw this but it will give you a mental picture of what you are dealing with. The garage is on the left, drawn at the lowest point of the slope.

 

EDIT: Crap. That is a terrible drawing. It does not show that the foundation wall should be at least 4" wider under the garage slab, to support it, and there is no thickness or edge turndown detail for the garage slab shown. It may as well be a cartoon.

 

I downloaded that drawing from CAD Corner. It is not the first time I have been dissapointed in their stuff.

@Dana,

Thanks for the reply. What I'm trying to figure out is the use of wall styles to make that drop into the garage. When I see the cross-section in that dwg, I almost wonder of putting a smaller wall style of just drywall and the 2x10 to solve that extra 15 1/2" dip (minus the 3" of concrete lip). So I'm really wondering if I can make that drywall on the interior wall construct just once, or if I need to do it twice, once for the mudroom & once for the garage at 12 1/2" taller, or other?

As for the window, no mfg is specified. I'm really looking into how to customize the window, door, and window/door assembly styles, for I am still scratching my head with the instructions given. I may need a more laymen translation.

Thanks!

I dunno about wall styles in MEP or Architecture. I've only used vanilla AutoCAD.

 

As a general rule, don't drop the wall framing into the garage. There may be some special circumstances where you might need to do something like that, but the wall would probably end up being double thickness where you would have to do it.

 

Just drywall down to the bottom of the ring joist of the 2x10 framing, or a little bit beyond, just to cover the join line. You can probably add that extra drywall into your section drawing without modifying the wall style.

 

The 2x10 floor system (or even another concrete floor) will completely cover the top of the foundation wall. That makes all the walls for that flooring system the same height, or I guess, the same style.

 

I just meant that section to be a generic example of how the garage to house transition works. That drawing is not correct in a number of ways. I should have proofed it better before posting it, and I don't have time to work on a good one today.

 

There will be an exposed curb (foundation wall) along the garage walls that adjoin to the house. In most jurisdictions this step down is required by the building code for an attached garage. Under no circumstances should the drywall overlap the concrete or masonry portion of the wall as is shown in that section. Also, NEVER let the edge of the drywall come in contact with the garage floor as is shown in that section. What happens to the drywall if you spill gasoline on the garage floor, or simply spray a garden hose in the wrong direction? In the field, the drywall mechanic will always hold the drywall up 1/2" or so for expansion on virtually every wall in the house.

 

Just drywall down to the bottom of the ring joist of the 2x10 framing, or a little bit beyond, just to cover the join line. The line between the 2x10s and the foundation wall does not slope, and the garage floor does.

@Dana,

As for the window, no mfg is specified. I'm really looking into how to customize the window, door, and window/door assembly styles, for I am still scratching my head with the instructions given. I may need a more laymen translation.

Thanks!

Is this house going to be built, or are you a student? If it's gonna be built, the window mfg needs to be spec'ed out by somebody pretty soon.

 

You could go to Anderson or Pella websites and look at the CAD drawings. Here's a link to Anderson's Professional resource page.

I changed that section drawing a bit.
