Framing for triangle window has framing at wrong angle and not abiding by RO setings in wind

[SHCanada2]

Customer wants windows at walls edge and wants to see how much space is between truss and window to figure out framing and casing sizes. below the truss will require a minimum of one plate

 

I cant get the wall framing detail to show the window, but a regular elevation can.

 

The truss is 12:12, but when I dimension the framing it is not 1:2 ratio height to width(which it should be for 12:12)...and you can also see the framing skew (not parallel to truss). Its also not framing below the truss(it is framing the wall to the underside of the roof. Anyone know how to force the framing to the underside of the truss (I suppose I can move it, but not ideal)

 

I'm using a tudor arch with 0 deg to create the window. I originally just tried adjust heights in left and right, but CA would not allow a zero and forced a 1/4".

 

Anyone know a solution to at least the first problem (framing not observing RO and not observing angle of window)?

does it on a stock plan, just not as bad

 

 

 

In my plan,, I changed the RO to be the actual adjusted value vs say 1 in, as 1 inch is on the angle. 1" on the horiz would be 1.4" and then for the vertical, it would be 1.41 at the top and 1 at the bottom. but that clearly didnt work.

 

I tried it on a stock plan and it actually comes pretty close, so not sure what is going on with my plan

 

 

 

 

although it does not reflect 10"  for some reason, 8 at the bottom 11 on the sides

 

so not exactly sure what it is doing

i deleted the window and readded, and now it is closer

 

still odd that it is outby 5/16. and the bottom has a tiny gap instead of same gap. must have something to do with the pitch,but the multiple by 1.41 doesnt seem to work....

In your second post, first image, you are measuring a point to a point and while the points on the window may be on the window, the other points aren't on the same edge of the framing. (See my image below.  I can't seem to avoid points on the window, unless I select the corner, but I have no points on framing, the measurement is to the member.) 

 

In your second post, second image, your measuring from a point on the window to a corner of the window framing.  If you zoom in the plane of your dimension extensions do not match the framing member's edges.  The top dimension extension is inside the rough opening (away from the framing member), the lower dimension extension is outside the rough opening (inside the framing member.)   

 

I've used both dog-eared and tudor to create a 12' x 6' window.  With auto framing on, and the dimensions pulled correctly, my spacing remains identical on the angle.  FWIW, whatever spacing you set the rough openings to be, Chief cuts them in half, centering the window top/bottom and left/right.  On angles the RO spacing is the altitude of the RO W:H triangle.  If you squared (**2) the angled RO that you want, multiply x 2, then take the square root of the result, it will equal half your window RO value,  √((4.25**2)*2) = 6.01 - this also shows you chief was rounding the 4-1/4" measurement to the closest 16th.   

 

Here my rough openings are set to W:12" and H:12".  Top/Bottom is 6" (1/2 of 12) and Angled sides are  4-1/4" (the altitude of a 6"/6" right triangle.) Notice the √(6^2/2)=4.2426, which Chief rounded to 4-1/4".

 

Changing rough openings to 8" for both W & H, auto framing changes to bottom: 4", and angled sides are 2-13/16" (the altitude of a 4"/4" right triangle.) Notice the √(4^2/2)=2.8284, which Chief rounded to 2-13/16"

 

Hope this helps.

thanks for taking a look. you are correct, it was picking off the top to corner of the framing. Which means then the framing member is not parallel to the window. So I did a CAD detail from view, and sure enough it is off. -44.76 is the angle of the framing member, where the window line is -45

On angles the RO spacing is the altitude of the RO W:H triangle.  If you squared (**2) the angled RO that you want, multiply x 2, then take the square root of the result,

that is what the 1.4142135 multiplier I have comes from, sq rt of 2 (i.e. for a 12:12 pitch, SQRT (sq(1)+sq(1)) =SQRT(2).

 

so in your example, if one wanted to get it "right" per se, where the RO is per the angles on the right and left, and on the bottom, shouldnt it be if you wanted for an RO of say 10 inches on the each side:

for the height

SQRT(10^2+10^2)+10 =24.142

which is SQRT(2)*10+10

 

and for the width

SQRT(10^2+10^2) + SQRT(10^2+10^2)=28.284

which is SQRT(2)*10*2

?

 

It also doesnt always look like it rebuilds the framing when making small changes to the RO

 

and then it decided to frame a box when i put it down to 2". any ideas on why that is?

 

but back to your plan, is your framing member at 45deg?

 

attached is the plan with an extra 35 on the width and it tells me in the dialog, the RO width is 179, but in the elevation it is only ~164

I can't figure it out.  I copied my walls/windows into your plan and my auto framing is still 45 degrees.  My windows are on the main level, then elevated to be transom height in the gable.

 

I copied my window to opposite attic wall in my room and lowered it and the framing angles were off.

I copied my window to opposite main level wall in my room and the framing angles were 45 degrees.

 

I copied my window to your opposite attic wall and the framing is off.

I copied my window to your opposite main level wall, raised it, and the framing was off.

when my framing is off it is at 44.750238 degrees.

Your window is at 44.800364 degrees.

 

It is maddening.

I forgot to add once the top of the window is set below the roof rafter line so that it can frame the opening square, then that is what Chief does automatically.  It only frames angles when it cant be framed square.

yes it certainly is

interesting, and odd...there would be nothing to nail the window to above the bottom plate
