Version 3.2.6 - 06.22.2023

Enabled the "Edit Truss Assembly" function for all gambrel attic trusses.
Enabled a gable wall cut for gambrel attic trusses.
Enabled a feature to selectively remove specific trusses from gambrel attic truss assemblies.

There are still a number of advanced options that need to be completed for this truss type, namely soffit and fascia need to be added.

The ability to edit this truss type is a fairly significant upgrade.

more thoughts on this - if you divide the trusses into parts - parta = main remaining assembly after section removal, part b = the vert roof (in this example), and part c = "flat roof" (in this example). and flip the truss (if possible) so only part of it needs to be componentized.

then you would have the trusses partly available for roof sections which would not have openings. the rest of the opening geometry would have to be manually assembled as part of adding the doghouse, access door etc.

Version 3.2.7 - 06.26.2023

Fixed a bug with the truss removal feature.
Enabled a feature to selectively remove specific trusses from common and monopitch truss assemblies.

Version 3.2.7b - 06.28.2023

Fixed a minor bug with the truss removal feature for all truss types.

*Note: This is a critical bug fix for common, monopitch, attic and gambrel attic trusses.

Version 3.2.8 - 07.05.2023

Enabled a ridge centering option for asymmetric gable rafter roofs.
Enabled a ridge centering option for asymmetric hip rafter roofs.

I think the non-centered ridge is the more correct of the two, but if you do want the centered ridge then it is also an option.

Version 3.2.9 - 08.28.2023
Fixed a critical bug with the truss removal feature for truss sets.

!!!! CRITICAL BUG FIX !!!!
I highly recommend upgrading from versions 3.2.7 and 3.2.8.

Version 3.2.9b - 08.28.2023 thru 08.29.2023

Fixed a critical bug with the hip rafter roof module.

Unfortunately I never noticed this error/bug because I usually test the plugin with the advanced options turned on automatically. If the advanced options are turned off and a hip roof is attempted and error will be thrown. This bug fix addresses that issue. I highly recommend upgrading to this latest version.

Version 3.2.9c - 08.30.2023

Fixed the non-orthogonal rafter framing bug for complex roofs.

I think I have finally resolved the confounded non-orthogonal rafter framing issue (it has been almost two years). It turns out the fix was simply replacing a complex piece of logic with two lines of code, sometimes simple is better.

I highly recommend updating to this latest release. I apologize that it has taken this long to rectify the issue, I was made aware of it about 18 months ago but it has taken me a while to circle back and determine the cause and then the solution. Thank-you everyone for your patience.

P.S.
After testing non-orthogonal roofs this afternoon I realized that it would be handy to have the ability to custom offset the rafter spacing for each roof plane. Sometimes the algorithm is not smart enough to correctly position the rafter exactly where one might want them. I will give this some additional consideration.

or you'd run a "nailer" rafter between them for the rafters to attach too as expecting them to line up o.c. with differing roofs is low. if you were manually building it, you'd want a common nailer along that line to attach to while keep o.c. spacing. more complex roofs - each roof section is its own assembly if the single common nailer doesn't work.

Version 3.3.0 - 08.31.2023

Added a rafter offset parameter for complex roof framing.
Fixed a minor bug with complex roof framing for half hip roofs set to custom pitches.

The rafter offset parameter will now allow the user to offset the rafter framing any custom amount (positive or negative) for each roof plane independently.

First look at a complex roof with the hips, flying hips and valleys drawn. The framing module still has quite a ways to go but at least this is a start on these elements:

medeek · 3 Sept 2023, 23:34

Version 3.3.1 - 09.03.2023

Added a hip, valley and flying hip rafters to the complex roof framing module.

The first thing you will notice is that the upper ends of the hip and valley rafters are not correctly trimmed, only the bottom ends. Also flying hips are not trimmed on their upper or lower ends. The trimming algorithm for these rafters is the next thing on my todo list.

Unlike the lower end trimming, the upper end will require a much more sophisticated algorithm so it may take some time. The problem really is that there a number of possibilities for termination and the plugin needs to be be able to check for all of those possibilities. No one said complex roof are easy.

medeek · 5 Sept 2023, 04:09

Version 3.3.1b - 09.04.2023

Refined the framing algorithm for hip, valley and flying hip rafters.

All of the major framing members are now being drawn however the trimming of certain rafters is still not quite correct, further refinement and correction will be necessary.

I've also noticed that with certain large roof planes an occasional stray edge is generated (or left behind when the roof primitive is created), I will need to look into this further and rectify the issue. It does not appear to be a critical error but it does effectively split the roof plane into to separate faces which then makes the plugin treat the roof plane as two separate faces.

With the flying hips terminating adjacent to valley rafters I'm not entirely sure how that is typically framed.

Please download and test this latest release and then email me comments or suggestions directly.

Version 3.3.1c - 09.05.2023

Minor bug fix within the rafter framing module for complex roofs.

medeek · 10 Sept 2023, 03:22

Version 3.3.1d - 09.09.2023

Fixed a bug within the global settings for complex roofs.
Updated the straight skeleton algorithm to better remove redundant edges within roof planes/faces.
Improved the robustness of the complex roof module (framing and cladding) for specific cases.

The complex roof module is now a bit more robust than it was and should be able to handle more cases than it did previously.

However there still does exist the special cases where the fascia line is not all on one level that is still not possible to draw. The discussion on that topic is presented in this video:

Hip and Ridge is still pending. Previously I was unable to fully work out the algorithm in order to deal specifically with flying hips. I will need to give this another hard look and see if my topological problem solving skills have improved since 2021.

Version 3.3.2 - 09.17.2023

Added statistics for complex roofs (Medeek Estimator integration).
