For a triple casement window I am thinking a single frame with three sashes, does this seem reasonable?

Also I was thinking about oval and round windows earlier today and they are really one in the same, the only difference being the aspect ratio (height/width).  A round window is an oval window with an AR = 1.0:

Hence the window height and width will drive the shape of the oval, really no different than a rectangular window.

Left, Right and Double:

View model here:

I've also addressed a bug with arched geometry where the push-pull direction was giving unpredictable results (flipping flopping between in and out).  Turns out that you need to clock your segments all in the same direction to get predictable results, which makes sense.  For some reason this did not occur to me as I was coding some of these sections of the main window module.
General Forum / Fink Trusses - Repair and Load Bearing Walls
« Last post by Toots on July 15, 2018, 10:30:50 pm »
Hi Nathan,

I'm at about the end of my rope trying to deal with my current house.  I am in a very rural area and I have tried in vain now for almost a year to find an engineer that will help me with this problem. 

First I'll describe my problem, and then the responses I've gotten so far.

I have a 1978 ranch.  It has fink style trusses spanning 28 ft o.d. to the exterior walls.  The first issue, is that I'd like to remove a small section of interior wall between our living room and kitchen.  It runs perpendicular to the trusses.  I am fairly certain it is not load bearing, but I'd love some input on that.  I'll tell you what carpenters and the one architect(not an engineer) that would at least talk to me on the phone have said below.  The tricky thing here, is that where the house turns a corner, they put 2x6 rafters to transition between the garage trusses and house trusses which are at 90 degrees to each other in orientation.  One end of the rafters actually sit on top of the trusses in the corner valley, so there are a couple trusses in there that are carrying considerably more roof load than any other trusses in the roof structure.  These also happen to be above where I'd like tot take that wall out....

The second issue, is that when I went up to examine the roof structure above the wall, several of the peak truss webs and some along the top plate of the roof have failed or are not in good shape. One or two completely popped off.  It looks like some of the web members(fir) twisted and popped the web off due to maybe humidity shifts.  The house has partition walls all over, and the trusses are spaced 16" o.c. so even with a couple failed trusses the roof hasn't gone anywhere.

Okay, so Problem #1, is the wall load bearing. There are three local architect firms(by local I mean within a 2 hour drive) that have a structural engineer on staff.  None of them will do residential work.  One was willing to send an architect to look at it for $500, but said they wouldn't work on it or provide designs because of liability and the age of the trusses and unknown manufacturer, and if they found any problems their engineers don't do residential work anyway.  Okay....not helpful.

One architect was willing to take about 15 mins on the phone with me even though his firm won't do residential.  He said the chances the wall is load bearing are very small to none because the bottom plate of a fink truss is designed to be in tension not compression.  Also, he said because there is no beam below the wall or anything else to carry the load to the slab in the basement, that automatically disqualifies the wall from being load bearing because a home would never be designed to carry roof load on your floor joists.  There is also no header above the doors in this wall.  The wall runs the entire length of the house but it jogs over several times, so it is not contacting the trusses at the same point along the whole house.  You can see the first 1 ft jog in the pictures.

The general contractors and carpenters(who came in person) all agreed the wall was not load bearing, but they didn't seem confident.  I could tell all of them were not really familiar with how trusses work.  Again we are very rural.  Again I'm a bit nervous because these trusses carry extra rafter load around the corner.

Now as far as problem #2 is concerned, I wouldn't consider doing anything with the wall until those truss webs are repaired.  I have searched high and low.  The architect on the phone didn't seem concerned, his exact words were "I'd just get some plywood and structural screws and sandwich the webs with 2'x2' pieces and get as many screws in as you can."  I know people repair gusset plates this way but it seems a bit cavalier in a "house fall down" type situation.  Again, I can't find any engineers to work on this.

Below are my crude drawings of the home, the wall in question from an end gable and top view, as well as a picture of the top plate of the wall in question nailed to the bottom of the trusses in the attic.  All members are fir.  Our roof snow load is 20 psf, but I understand builders use 30 psf in the area out of caution.

Any input or guidance is GREATLY appreciated.  I'm desperate at this point to fix this.  Even if I can't get that wall out I have to get those webs repaired(but I really want that wall out).

I"m not sure why you would want to put a single shutter to one side of a window but here it is just in case you need it:

I will have to wait until tomorrow to roll out all of the shutter updates its now 4:00AM and I'm done for now.

I think I've now beat this horse to death, shutters are available for rectangle and arched windows in all styles and geometry (Left, Right, Double).

After I add more window types I will probably need to revisit the shutter module but I don't think shutters are very common for more exotic window shapes (ie. ovals, triangles, trapezoids etc...)

I guess I haven't been defeated after all.  Using the follow-me method I was able to get it to work:

I now have all the shutter types working for arched windows:

Arched window with flat panel shutters:

These arched shutters are proving to be a bit more challenging.  I will need to figure out a new algorithm for board and batten shutters and louver shutters.

I don't have a half hip (rafter roof) setup yet however there is probably a workaround by combining a gable with a hip and then using the trim tool to manually trim some of the rafters, however I haven't really tried this at least not for a real design.

I took about 10-15 minutes and tried creating a half hip with a gable and hip roof as primitives.  Using the trim tool made it fairly easy to clean up the rafters, see results here:

Since the end result is not parametric you will want to be sure that you have all of your rafter depths, overhangs etc... set before you dive into the manual editing of such a roof.

This is obviously a painful and slow process.  Conclusion, I need to add in a half hip rafter roof.

Board and Batten Shutters:

Version 0.8.6 - 07.14.2018
- Added shutters: Solid, Flat Panel, Raised Panel, Louver to rectangular windows.

View model here:

Available shutter styles are:

- Solid
- Raised Panel
- Flat Panel
- Louver

I have not yet enabled shutters for arched windows, that will be next.

I also need to add in a board & batten shutter which is also quite popular.

Also note that you can position the shutters on either side of the window (left or right, single shutter) or the more common double shutter configuration as shown.
