When combining different roofs on complex structures I often find myself having to delete the outlookers, overhang and gable end truss on one end of the roof assembly. Then today I had a request from a user to enable the ability to limit the gable geometry to only one end. Based on this I will try to set up another option for the gable end truss option which allows for only the creation of one side with the gable end geometry. This means I will have to rework some of the advanced options to make sure it is compatible but I think I can make it happen fairly quickly.

In response to a recent request about gable ends of the roof assembly I have created an additional option in the "Gable End Trusses" option when creating common trusses.  The new "Front" option only creates the gable end truss and gable end geometry on one side of the truss assembly and leaves the other side open as shown below:



This should come in handy when creating roof assemblies that butt up against walls and other complex configurations (ie. T-shaped buildings requiring Valley Sets etc...)

I've also been slowly working away at bringing all of the common truss types up to speed.  The Modified Qeen Truss (Mod Queen) now has plates, raised heels, structural outlookers, layers and materials:



Most of the non-common truss types still need me to go through and integrate plates, layers, raised heels and materials, the amount of work needing to be done is staggering.  This plugin is far from a polished, finished product, even after more than a year's worth of time and effort.

I'm quite familiar with all of the industry names for various configurations of roof trusses (ie. Fink, Howe, Mod Queen, King Post, Queen Post, Double Fink etc...)  What distinguishes these trusses from each other is the configuration of the webs of the truss which is dictated by the number of panels of the top chords and bottom chords.  For example the Howe truss is four top chord panels and four bottom chord panels (4/4).  Most diagrams show up to a Triple Howe truss (8/8).  What is not typically shown is an (8/6) and (8/7) truss, is there any reason for this?  These two configurations seem perfectly valid to me, I would call them a Triple Queen and Fan Fink truss respectively.  Has anyone come across either of these two configurations?

Actually I would change the name of the Fan Fink to Double Fan.

The next size up would be:

Quad Fan 10/5
Double Mod Fan 10/6
Triple Fan 10/7
Quad Queen 10/8
Quad Fink 10/9
Quad Howe 10/10

As the number of panels increase in the top chord the number of potential variations increases.  So for a four panel top chord truss the number of variations is three, the general pattern is:

(2/x) truss = 1 possible configuration
(4/x) truss = 3 possible configurations
(6/x) truss = 4 possible configurations
(8/x) truss = 5 possible configurations
(10/x) truss = 6 possible configurations
(12/x) truss = 7 possible configurations
...

The common fan truss now has raised heels, plates, materials and layers:



I apologize for the slow progress.  I've had some 12 hour work days last week so I didn't have much left in the tank once I got home, usually just eat and then went straight to bed.

Version 1.8.3 - 02.12.2017
- Enabled metal plate connectors, materials and custom layers for Fan trusses.
- Added energy/raised heels for Fan truss (3 variants: wedge, slider and vertical w/ strut).
- Roof slope can be toggled between Pitch or Degrees (input) for common trusses in the global settings.



Currently the metric template forces the roof slope to degrees however in the imperial templates (inches, feet) the user can select between Pitch or Angle for common truss types.  I will need to update all of the truss types with this global setting option.

Version 1.8.4 - 02.14.2017
- Enabled roof cladding for gable and hip rafter roofs.
- Roof slope can be toggled between Pitch or Degrees (input) for gable and hip rafter roofs in the global settings.

To create this roof was not an entirely automated process but I'm slowly getting there.  The trim tool comes in really handy for creating valley and jack rafters but ultimately it would be nice to auto create L-Shaped, T-Shaped and U-Shaped roofs.

First new roof type in added in quite a while.  Lately I have been focusing most of my effort on cleaning things up and making sure all the options are working correctly for each roof type and configuration.

Soffit cuts with TJI (I-Joist) rafters gets a bit interesting but I've finally implemented it:

Trying out the Rayelectron Rendering plugin, I'm fairly impressed.
