Tutorial 25: Estimating Complex Roofs (13:13 min.)

Version 3.3.3 - 09.22.2023
- Improved the responsiveness of the "Edit Roof Plane" tool and the "Move Roof Edge" tool for complex roofs.
Previously when a complex roof was positioned on top of any wall assemblies and either of the two tools mentioned above were executed there existed the possibility of collinear edges with the roof assembly and the wall assemblies below. This conflict would then not allow one to properly select the desired roof edge unless the wall assemblies were hidden, or put on a hidden tag/layer. This fix should mitigate that problem and allow one to select a roof edge (on the roof outline) without having to take that additional step.
I highly recommend upgrading to this latest version if you are using complex roofs.

Tutorial 26: Complex Roof Primitives (6:42 min.)
-
Version 3.3.4b - 10.02.2023

Tutorial 27: Drawing Complex Roofs (6:01 min.)

Tutorial 28: Drawing Complex Gable Roofs (4:16 min.)

Version 3.3.5 - 10.06.2023
- Sheathing Vertical Offset parameters added for common and monopitch trusses.
- Cladding Vertical Offset parameters added for common and monopitch trusses.
By customer request.
This feature is already implemented within the Wall plugin so it is about time that I bring the Truss plugin up to speed as well. I think these four parameters are self explanatory enough that I don't need a tutorial video but if I do please let me know.

I still need to come up with a good porch module for wrap around porches and the like, but in the meantime with some careful use of the SUBTRACT function one can get pretty close:

@medeek -- no spray foam?
actually, probably changing the material on the rafter insulation (first image) would probably represent. -
Version 3.4.6 - 05.16.2024
- Enabled sheathing, cladding, ridge cap and labels for dual pitch trusses.
- Updated the polynesian truss so layers and materials are properly assigned.
- Enabled the "Edit Truss Assembly" function for dual pitch trusses (imperial and metric units).

- Enabled the "Edit Truss Assembly" function for bow barrel trusses (imperial and metric units).
The edit and regen functions have now been enabled for all active truss types within the plugin. However I still have four truss types that need to be setup and activated.

I now have the basic system in place and working for the rafter roofs but if you look closely you can see there is still some refinement necessary. The example shown is two gable rafter roofs that are connected, with the trimming of the primary roof limited to only framing, cladding, gutters and soffit/fascia. Note that the insulation, gypsum, rafters and sheathing is not trimmed on the primary roof:
The tricky part with the refinement is how best to generate the cutting solid to subtract away the unwanted portions of the roof(s). Currently the way I am doing it is using the hidden roof primitive and the roof outline. I basically take the roof outline, extrude it vertically down and then union this solid with the roof primitive above. The resulting solid is then used to subtract against the geometry of any attached roofs. This seems to work reasonably well in most cases but as you can see with the soffit and fascia (and the gutters) there is some overlapping and other minor complications. The insulation also gets a little carved out in places but it is mostly acceptable.
Thoughts or suggestions?

Version 3.4.7 - 05.23.2024
- Enabled Roof Connections between complex roofs, rafter roofs, truss roofs and solid groups.
- Added the "Configure Roof Connection" feature to the edit menu for complex, rafter and truss roofs.
This is not a completely new feature however the configuration capability introduced (and the level of granularity achievable) is new and somewhat experimental at this point. I'm sure it will take a few updates and versions before all the issues are worked out and all the necessary refinement is achieved.
Also note that that not all rafter roofs and not all truss types have this feature enabled yet. The following rafter roofs have been enabled:
- Gable
- Shed
- Shed w/ Ledger
The following truss types have been enabled:
- Common
- Monopitch
- Scissor
- Attic
- Tail Bearing
- Symmetric Cathedral
- Cathedral
- Parallel Chord
More to come soon...
