3D Truss Models

Back to complex roofs. I've been giving some thought to complex truss roofs and how to handle L-shaped roofs and their derivatives. Basically there is three ways to frame them out, which one is the most standard or preferred?

Valley sets can get a little interesting when you start dealing with intersecting hip roofs. If the width of the projection were to increase the valley set would become a combination of standard valley trusses and flat top or hip valley trusses.

Version 2.0.9 - 11.25.2017
- Structural outlookers (vert. & horz.) enabled under advanced roof options for Parallel Chord truss type.
- Metal plate connectors now enabled for all parallel chord trusses.
This truss type should now be up-to-date with all of the advanced options available:
roof returns, gutters, ceiling drywall, ridge cap etc...

I was discussing the plugin with a family friend and he suggested I offer a student version of the plugin (ie. fully functional but time limited to one year and purchase requires a student ID).
I already offer a trial version (freemium model) that is limited in its functionality.
Is there any need for this?

Some sort of educational version might be good, or licensing to school or class that has an expiration so it is harder to pirate... It may be some teachers would like to use it to familiarize students with construction methods, besides the modelling aspect.

Is there some way you can incorporate a method for exporting/importing settings (user defined layers for example) in your various extensions? I'm migrating to a new machine and this seems like a useful feature, even though it may be one that will probably not be used a lot.

Version 2.1.0 - 11.28.2017
- Added Northeast hip set trusses.
- Enabled advanced options for northeast hip sets.
- Added energy/raised heels for northeast hip set (3 variants: wedge, slider and vertical w/ strut).
- Added the option for open vs. closed end jacks.
- Added the option for a drop in purlin frame.
- Enabled a graphical user interface for Truss Set selection.
I only plan on adding the midwest and california variants if requested.
I don't want to toot my own horn but these truss sets are quite complex, I'm still amazed that I've been able to finally write the code to generate all of this geometry. At first it is a bit overwhelming but when you break it down into its components and slowly grind each one out sooner or later it emerges.
I still have not added plates to the truss hip sets due to the complexity and the fact that it is low on the priority list for now. Complex roof are currently my biggest hurdle and I am still battling with how to best approach these from a systematic standpoint and then dive into the details once the overall layout is configured.
Until I have complex roofs figured out the plugin is only about halfway there, but at least I've got my foot in the door and I'm making progress.
When you consider that you can create one of these hip truss sets literally in seconds with all of the sheathing, cladding, fascia, gutters etc... and it is all geometrically correct, it is pretty cool. Manually it would take me well over an hour to try and generate this level of detail without the plugin, there is something to be said for automation.

I don't know how to do it on a Mac but if your running Windows you can probably pull the settings directly from the registry and then insert them back in on the new machine.
I will give this some thought.

The reason I am taking so long with complex rafter and truss roofs is the possible permutations is making things very challenging.
For example take the truss roof below:
I'm assuming there are no interior bearing walls and we want to clearspan the entire building outline. I can get the basic roof and truss layout by creating to hip truss sets as primitives but that is where it then becomes very interesting.
As you can see there are two mid-building girder trusses that then catch the mono pitch sub-girders which are each supporting two common trusses. Next to the sub-girders is a small valley set (half valley) that fills in the roof behind the sub-girders.
The largest span is 36', which is reasonable. This appears to be the simplest way to truss this roof out but is probably not the only solution. A good truss technician could tell me how close I am to the optimal solution.
Granted the complex rafter roof is not IMHO as hard a problem but it also has similar difficulties and issues.

C'est merveilleux, merci beaucoup.

I will make corrections on the post above!

French translation of the Roof Truss Menu:
I will roll a sub revision so everyone can try it out.
-
It's a beginning!
Have you a system of translation ?
Or I must edit some files ? -
I am still compiling the list of words and phrases, there are a lot of menus, too many.
-
That is the problem of very detailed program!
Ps I can make an adpatation of this page in French!
Only for the fun, (It's my hobby)
So that will be a cool training for the future Panel's Truss Translation!
Yet made Twillight, Podium, FlexTools, Groboto (collector), ZBrush, SimLab Composer,
3DCoat (Manual), PolyBrush, Qubicle2, SUbD, Profil Builder2, Moi3D, GifCam, Monolith (manual), [url=http://visualizervf.weebly.com:26zyq7ev][u:26zyq7ev]Visualizer[/u:26zyq7ev][/url:26zyq7ev], [url=http://visualizervf.weebly.com:26zyq7ev][u:26zyq7ev]SolveSpace[/u:26zyq7ev][/url:26zyq7ev] etc...and so many UI, Manuals, curiosities etc...
I'm frightened by this list!

Wow, that is pretty amazing.

Look at your Private messages!

As the number of advanced options have increased (common trusses) the user input menu has slowly grown in size until it is so large that it often does not fit the screen of many laptops and smaller screens.
This problem has been well documented by a number of users for quite some time.
This weekend I spent some time putting together a new HTML menu for advanced options for roof trusses:
I still need to work out the metric version and also all of the language translations but otherwise I think it is almost ready to roll out.
As you mouse over each of the options a 320x240 image will display as shown, hopefully clarifying the meaning or usage of each parameter/option.
