3D Truss Models
-
Version 1.9.7 - 08.26.2017
- Added king post timber trusses with bolts and metal plates.
There may be a few bugs to work out as I haven't had the time to test every possible configuration but it appears to be mostly working now. The metric version is not quite ready so the GUI defaults to the imperial units regardless of the template.

I will add in the Queen Post and Howe configurations if requested by users and make any other corrections or adjustments as needed.
The permutations with this thing is ridiculous. The truss above has larger members with a wider plate width that allows for two rows of bolts.

We got about 50% the way there which in my mind is pretty good. I don't know that Kickstarter was the right venue for trying to stir up the momentum for a SketchUp plugin but I thought it's at least worth a shot. I sincerely appreciate all who have pledged their hard earned money and supported me in this endeavor. Your faith in me is the reason I keep plugging away at these tools.
I am currently pursuing other funding options. To produce a wall plugin that can do what the other "big boy" softwares can do will take a serious investment of my time and effort. I'm am figuring at least two years of solid programming to produce a polished product that has all the bells and whistles.
How I get there, I'm still trying to figure out. Currently I spend my weekends and a small amount of my time during the regular work week (usually going after the low hanging fruit). Surprisingly I am able to make some headway but progress is too slow in my opinion, somehow I will need to speed up.
Again I would like to thank everyone who participated in this campaign and for all of your pledges, it means a lot to me.

Looking at the code structure of the timber truss module and the html web dialog it doesn't appear to be too difficult to add in the Queen Post and Howe type truss. This addition will make this feature considerably more versatile and useful in my opinion since it should cover 90% of most timber trusses of this type used in residential and commercial construction.
I will make it a point to add in both additional truss types before moving on to something else.
Recently I have not had a lot of feature requests so please fire away.
The next big item on the list is the implementation of the straight skeleton algorithm and the ability to create any rafter roof shape, this is a big one. If I succeed, which I will, this should be tremendously valuable to many of the plugin users.
How to do this sort of thing for truss roofs becomes a bit more difficult since truss roofs are a bit more ambiguous and can be pieced together in a variety of ways. I think it is possible but I will need to give this one more thought.
The next big item which needs to be tackled is the ability to generate floor joists and trusses for any floor outline. I've already given this some serious thought and the path forward is clear to me but it will just take some focused coding time and debugging. Along the same lines, the ability to cut holes in the floor assembly (stairwells, access doors etc...) is also a hot item, I will address this at the same time.
Work on the Wall Plugin has begun in earnest but my free time right now is limited so meaningful progress is slow, especially as I am still devoting the bulk of my time towards the truss plugin.
I have exactly zero feedback on the timber truss module so I am curious if anyone has used it yet and if they are encountering any difficulties or other issues that they would like to see addressed.
-
Is this feature useful?
-
What would make it more useful?
-
Would other timber truss types (timber rivets, etc...) be more useful?
Just because I find it fascinating and would like to add it to the plugin doesn't mean it has any real world utility, I've learned that through experience.

Plates are mostly there now just need to work on the bolts for the Howe Timber Truss:

Bolts and plates are now complete for the Queen and Howe Timber Truss types:
Please feel free to test out the web dialog at the link above.
Now all that remains is to bring the javascript code into the ruby.

Timber trusses haven't seemed to garner much interest or feedback but I do feel like it is a worthwhile contribution to the plugin.
There is more to be done with the engineering side but I will move on to something else unless customer feedback brings me back to it.
The big prize right now is the straight skeleton implementation. I have been mulling this one over for at least a year now.
The truss yard now has 23 different truss types/profiles:

Version 1.9.8c
- Enabled option for F436 vs. F844 flat washers for timber trusses (in the materials tab within the global settings).
Version 1.9.8d
- Updated license registration system.

I do keep an eye on my ratings in the PluginStore and I've noticed that I am consistently at the low to mid three's (3.0 - 3.5).
I appreciate the ranking but I would better appreciate the ranking if it was followed up with some feedback. Why 3 and not 5? What can I do better or fix? What am I missing? Where is it broken? What is clunky and counter-intuitive? Is the price too high? Is there enough value for the money?
I do have a long list of things that need work but this type of feedback would help me further prioritize this list.

I've had a bug report regarding the Gambrel Truss and Timber Truss features when using the plugin on MacOS. I am curious if any other Mac users are also experiencing issues when html or webdialog menus are being employed by the plugin.
I've put more information on this developer's thread here:
http://sketchucation.com/forums/viewtopic.php?f=180%26amp;t=68011
If you are experiencing similar issues please contact me directly at nathan@medeek.com
I would like to resolve this issue as it poses a serious problem for Mac users and will be a much larger problem as I slowly migrate to more Html based menus in the future.

I've started putting up all of the previous versions of the plugin here:

Hello Nathaniel.
Some thoughts for your consideration:@unknownuser said:

I agree, this is a very big one for us.@unknownuser said:

Yes, essential for both. I would add (I may have mentioned it before) the need for a floor assembly to sit WITHIN a foundation wall so as to have the main floor level perhaps no more than 8" above grade. Clean walkouts to grade.@unknownuser said:
Work on the Wall Plugin has begun in earnest
Excellent. I have comments for you on the wall tool thread.@unknownuser said:
The timber truss module. Just because I find it fascinating and would like to add it to the plugin doesn't mean it has any real world utility, I've learned that through experience.
Your comment and implied question on 'world utility' brings me to the following observations:
I do not believe many of the truss items you are developing, such as plates, bolts, gussets, etc.---all of them very specific engineering components---are required by your present user base. In fact, we cannot use them. It is almost as if you are writing code for structural engineers, when in fact, P.Eng's have their own software to overlay their drawings over our working drawings. They would not use your plugin for what they need to produce for us designers (in the broadest sense) as they have their own.
We need your truss plugin, along with the floor/foundation and wall tool to help us speed up the building design process, NOT produce stamped structural drawings from them ourselves for local jurisdictional approval. Simply put, even if we wanted to, we are not allowed to produce engineering drawings with your plugins. Hence the P.Eng.
As such, if it might be possible to move away from all the structural components (dealt with, as I say, by others and their software) and put the focus on speeding up the design process itself for walls, floors, foundations, and roofs to say, the 80% level (leaving structural to others) that would give us the speed--the essential utility----we are looking for.
I will bring it up on the other thread, but SONDER's drawings are a very good example of the direction working drawings are taking: at 1/4"-1-0" we need very little information in any given cross-section (note the grey area in his attached section). It is in the detail drawings (Nick's are the best I have seen in a long time: superbly expository) where information for a builder can be placed. They are not needed in a cross-section unless it is at a far larger scale, and even then they can be produced as separate files and brought into Layout for final output.
Provide us the ability to speed up our building design process with your plugins (soon to be one, I trust). If so, it will, as I have said before, become a game-changer.
As always, these plugins have my vital interest and I offer you my sincerest best wishes for continued success. It is evident to me you are doing premium work.

Thank-you for your excellent feedback and comments. I think this is probably some of the best advice I've have had in a long while with regards to the general direction of my "architectural" plugins.
With regards to Item #2, please send me some details on your floor assembly that sits within the foundation. I need to understand how this construction comes together and works.
Realize that the genesis of the Truss Plugin actually came from my Truss Calculator which is an engineering analysis tool and not a design tool. I kind of came into the plugin world with an engineering mindset but have slowly evolved into a design tool developer as the client base has pushed me progressively in that direction. In an effort to make the plugins more useful I have tried to keep the big picture in mind but sometimes I get sidetracked and fall back into my engineering ways.
Ultimately, I have plans to develop a plugin specifically for residential structural engineers, and it will be a game changer for engineers like myself, especially if I can fully automate the load takedown, analysis and report generation.
I realize that some of the details are probably not needed in the generation of a roof or model but at the same time I enjoy making fairly realistic models (I'm not into cartons). Hence, the truss plugin has been enabled with details such as plates, rakeboards, sub-fascia, gypsum, ridge cap etc... I have been considering adding in some more advanced options such as soffit, fascia, barge board and soffit boxes to better finish off the roof. I will be requesting more feedback on these items moving forward to make sure that they are something needed or wanted.
Speeding up the design process is really what it is all about, I get that. If the designer can create an entire roof in a matter of seconds versus spending hours manually drawing all of the various elements this is certainly worth something. However, the plugin needs to be able to take care of all the details without bogging down the designer, if the details are to be included. The truss plugin currently can successfully do this for a simple rectangular roof or floor outline (hip or gable) but as soon as you get into anything more complicated it again becomes a manual process and the details become more a hinderance than a help
With the foundation plugin I have attempted to address the non-rectangular footprint with some success. However, the final step is to provide a preview screen which will allow one to accurately place and preview potentially multiple internal bearing points/footings.
Items #1 and #2 are big and would push the Truss Plugin to the next level.

Hello Nathaniel
I appreciate being able to provide you feedback as per your invitation to do so. It also helps me think through what I could most use for my house modelling.

Please see the attached sketches from Rob Thallon's book GRAPHIC GUIDE TO FRAME CONSTRUCTION (it has been an invaluable reference to me since I bought it quite a few years ago now). The sections he drew show clearly what I have referred to as 'floor assembly within the foundation walls'.@unknownuser said:

Never a problem. I value the context of your coding journey.@unknownuser said:

I did not know this, but I fully agree: it will be a game-changer, not only for engineers but for firming up the communication and synchronicity of drawings with SU as the platform for both engineers and designers. Your direction here is a very good thing, I am convinced.@unknownuser said:

We want all of these 'menu items'. They fully support and speed up detailed modelling.@unknownuser said:

Now, this can be an ongoing--and compelling---conversation with us, your user base, as you sort out how to go about coding for modelling complexity. This is an attractive problem to solve, I can only imagine.@unknownuser said:

Very cool indeed......
A tip o' the hat.

Version 1.9.9 - 09.12.2017
- Added a hip & ridge option for gable rafter roofs.
- Fixed some miscellaneous bugs with rafter roof modules.
There were some really annoying issues with the rafter roof module that needed to be addressed. I still have more work in this regard since I need to go through all of the other rafter roof modules (glulam beam, dual glulam beam etc...) and clean a few things up but I made a fairly good dint in it this evening.
At some point I would like to also add roof returns to the gable rafter roofs, this should not be too big of an issue. Another thing to add to the todo list is partial roofs where a rafter roof butts up against a larger wall and/or roof.
The list never ends, but then I never quit, I'll probably still be working on this thing 20 years from now when I'm 65.

Framing the floor joists flush with the sill plate seems to be particularly popular in Oregon, I've never seen this done before until I did some structural jobs in that area.
I've seen a number of configurations and details. Some actually use pockets in the stemwall, others use the ledger method as shown in the images above. I've also seen where the ledger is below the joists which then directly bear on the ledger. I will see what I can do in this regard.

Popular in California too. Good connection of floor diaphram to foundation. Used where the grade outside may be higher than the crawl space, or a waterproof terrace is adjacent (in which case the curb may also be raised and the sheathing is NOT over the mudsill). The disadvantage is in running power and plumbing up through the wall.
-
Two issues with this system:
-
As noted above getting the utilities into the wall from the crawlspace presents a challenge, especially plumbing.
-
Insulating for cold weather environments is also difficult. Where the corner of the interior space is almost in direct contact with the stemwall creates a thermal bridge.
The major advantage of this system is less sheathing needed for exterior walls since you don't have to add in the height of the rim joist.
