3D Truss Models

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.

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.

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.

pilou

It's a beginning!

Have you a system of translation ?
Or I must edit some files ?

medeek

I am still compiling the list of words and phrases, there are a lot of menus, too many.

pilou

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!

medeek

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.

Help Image is a very very good idea!
Very very first draft as you can see the "?" !

I am trying to understand how the Mac .plist file works. Is it similar to the registry? I have a client that is having some trouble with registering (inputting their serial into the global settings) and having their system save the serial number.

Unfortunately, I don't own a Mac so I am not much help. Does anyone use the plugin on a Mac and have had similar problems with saving the serial number? Where does one go to manually edit the .plist file and enter in the serial number manually.

not only that
i had the same questions
so i bought a mac: https://en.wikipedia.org/wiki/Mac_Mini
sheap, you can use windows mouse, keyboard and screen
there are a few things to modify in the ruby code por windows, to make it work on a mac

I am working on adding the heel blocking since it is an option listed in the advanced options.

So far there has not been much call for this feature but a few people have inquired so I figured we might as well add it in for completeness. The red coloration is for clarity in the image above.

I will probably add the option to allow for venting holes since this is fairly typical in my neck of the woods.

pbacot

Very important. Sometimes the heel blocking, when taller, is a truss manufactured square that might have sheathing.
