3D Truss Models

Version 2.6.5 - 12.18.2019
- Enabled an "orthogonal mode" for the complex roof draw menu.
- Added the ability to delete points in the complex roof draw menu.
Clicking the "Ctrl" key will enforce orthogonal mode while using the draw tool. Currently the orthogonal mode will restrict the user to 45 deg. increments.
While selecting the points for a roof outline the user may accidentally select an incorrect point. By clicking the left arrow key the user can delete the previously selected point (or multiple points). I will probably also incorporate this same feature within the draw menus of the foundation and upcoming floor plugin.
Both of these improvements are a result of plugin usability discussions with Larry Belk.

As we begin a new decade the number of licensed users of the Truss plugin is currently at 1,200. The plugin is now just over 4 years old, it will be interesting to see what we can do with it and the other plugins of the mdkBIM suite in this coming year.
I am looking forward to completing the complex roof module as well as bringing the truss side of the house up to par with the rafter side within this module.
Beyond that, it is the new floor plugin and project plugin as well as completing some key items with the wall plugin.
Wishing everyone a happy and prosperous New Year.

A study of intersecting roof planes and trusses:

I didn't spend any time trimming truss tails or worrying about the sheathing or cladding, I was mostly interested in the truss layout and roof planes.
Note that I created the tertiary roof plane in order to then draw a solid (temp rafter) which I then used as the primary roof plane for the second valley set (45 degree).
I've colored all of the temp geometry transparently so you can dissect the model a little easier.
I'm not entirely sure if this is how a truss manufacturer would actually handle this type of situation, but this is my best guess.
-
I fired up a different truss type that I have not used before - attic truss. I work in metric (mm) but the attic truss is only imperial (ft / in). Roof pitch I work in is degrees, but am facing 1/12 ratio in imperial? Did I miss a setting somewhere?
How many of the other trusses / subsections are not homogeneous to each other? Can all the section / subsections be brought onto par with each other?
-
There are still a few truss types that do not have all of the advanced options available to them. To the best of my knowledge only the attic truss still does not have a metric interface when using a metric template in SketchUp, I will work on this.

Version 2.6.6 - 01.29.2020
- Fixed a bug in the (complex roofs) roof plane edit menu for the outlooker size parameter.
- Fixed a bug involving truss assemblies and valley set assemblies that are created in the same SketchUp session.
-
Version 2.6.7 - 02.09.2020
- Fixed a bug in the text input method of the draw menu for complex rafter roofs.
- Added a T1-11 built-in material into the material library.
-
Version 2.6.8 - 04.10.2020
- Fixed a show_modal bug for macOS in the Timber Truss HTML menu dialog.
With this latest release I've had to migrate to the .rbe encryption system so this version will no longer run on SketchUp 2015 or earlier.
-
Version 2.6.9 - 04.11.2020
- Enabled the "Edit Truss Assembly" function for all parallel chord trusses (imperial and metric units).
- Labels and callouts added to parallel chord trusses.
There are still a number of truss types and rafter roofs that still need edit capabilities, I am slowly working through this list.
-
Version 2.7.0 - 04.12.2020
- Enabled the "Edit Truss Assembly" function for all timber trusses (imperial and metric units).
-
Version 2.7.1 - 04.13.2020
- Enabled the "Edit Roof Assembly" function for shed w/ ledger rafter roofs (imperial and metric units).
- Enabled soffit and fascia for shed w/ ledger rafter roofs: boxed, gable, angled.
- Enabled a roof cladding extension parameter for shed w/ ledger rafter roofs.
- Added the option in the shed w/ ledger rafter roof edit menu to specify a separate front and back overhang length.
- Enabled a "No Framing" mode for shed w/ ledger rafter roofs.

Skylights have not been on my official todo list but now they are.
I've actually been tossing the Skylight idea around for a while now, how best to implement it within the various roof modules. I've got some ideas already but I haven't finalized it yet.
Does anyone have any specifics or suggestions on the actual skylight models/components that I should use. Specific brands, reference drawings, that sort of thing.
My thinking is to have some fairly generic skylight models that the user could chose from. The skylight module would then bring these components into the model and also cut the corresponding holes in the roof cladding and sheathing. I would also have a tool for editing and deleting a skylight. As far as moving the skylight on the roof plane, I would allow the user to simply click into the roof assembly and moving the skylight with the native tools as they see fit, this would be the simplest way of handling re-positioning.
Again, I'm still tossing this idea around, trying to shake out the best system for implementing it, any feedback is appreciated.

Velux has their official models in the warehouse but as usual there are too many details in these models, so I had to create my own low poly versions that are dimensionally accurate:

Different manufacturers have different sizes. A single well constructed DC, where you can enter the overall sizing on a dialogue, would probably be more useful and cause less bloating of the extension?

First look at the Skylights Toolbar:

I've thought about this however there are quite a few different types of skylights (ie. surface mount, curb mount, round etc...) so it would seem to make more sense to model a few of the most common ones and then allow the user to drop their own custom skylights into the library folder. However, I do get what you are saying on this, I may need to give it some more thought.

Maybe touch base with Yoni at FlexTools, they seem to have that process licked!

Surface mount and curb mounted (typically on 2x6 framing over roof deck) are common. Velux is probably the standard though there are other types out there. In our area it's mostly Velux or something like that due to stringent energy requirements. You could have some of these, especially the ones meant to go into 24" o.c. framing. Then if you want branch out to some pyramidal or gable style skylights.

Version 2.7.2 - 04.24.2020
- Added wall sheathing thickness and wall cladding thickness parameters to the advanced options for trusses.
- Enabled advanced options for tail bearing trusses.
I still need to enable editing and labels for tail bearing trusses.
-
Version 2.7.2b - 04.24.2020
- Enabled the "Edit Truss Assembly" function for all tail bearing trusses (imperial and metric units).
- Labels and callouts added to tail bearing trusses.
This update also resolves a potential bug that could cause the plugin to go into a infinite loop if the birdsmouth cut exceeds the depth of the top chord of the truss. If you are using tail bearing trusses I highly recommend upgrading to this latest release.
The updated module is now properly creating the gypsum on the underside of the truss (three pieces).
