Needing a break from the rigors of the straight skeleton code I realized that I have still not implemented the octagon hip roof yet.  On a related note the circular roof could also use my attention:

View model here:

The number of rafters can be given by this equation N = 8 + 8n where n = 0,1,2,4 etc...

In this model n = 3

If you really want a headache try and truss out this same roof outline:

After about 45 minutes I've given up, not because it can't be done but because the amount of custom truss profiles and manual editing required far exceeds my patience and determination.

Starting to work on the straight skeleton algorithm today, complex roofs have got my attention.

The model below has a saddle point and this lends itself to some rather complex framing:

Even with the roof primitives and trim tool, which helped out tremendously, it still took me almost an hour to fully generate the roof framing. 

The goal is to turn hours into seconds.

As I previously mentioned I am slowing working on making all previous version of the plugin available here:

Each new version adds improvements and fixes.  Probably at some point once this plugin has fully matured then I might see a good reason to install a previous version, but hopefully I never get to that point where the plugin becomes bloatware.

I suppose the only reason to install a previous version is if you have an expired license and do not wish to upgrade, I can respect that, especially if you only use the plugin on a infrequent basis.

I've been thinking about multi-level roofs and how to deal with them.

Currently I don't see a good way to automate truss roofs, I think there will be some manual intervention required.

For rafter roofs though I think I can fully automate the process.

Version 1.9.9 - 09.12.2017
- Added a hip & ridge option for gable rafter roofs.
- Fixed some miscellaneous bugs with rafter roof modules.

There were some really annoying issues with the rafter roof module that needed to be addressed.  I still have more work in this regard since I need to go through all of the other rafter roof modules (glulam beam, dual glulam beam etc...) and clean a few things up but I made a fairly good dint in it this evening.

At some point I would like to also add roof returns to the gable rafter roofs, this should not be too big of an issue.  Another thing to add to the todo list is partial roofs where a rafter roof butts up against a larger wall and/or roof.

The list never ends, but then I never quit, I'll probably still be working on this thing 20 years from now when I'm 65.

Medeek Wall Plugin / Re: Development and Updates for the Medeek Wall Plugin

My idea is to have a specific layer which the layout tool places all of its 2D layout geometry, something like the image shown below:

It will probably take a while to fine tune the layout tool so that it is robust and has enough flexibility to handle 99% of most wall framing situations.

View model here:

My idea is color code openings (windows, doors, garage doors) for easy identification.  The same holds true for wall types (Ext./Int., Int./Int.).  With the walls I am thinking about providing a 1 inch strip on the exterior and interior to indicate the "normal vector" of the wall and provide a visual representation for the sheathing and gypsum.

When using the door or window tool to insert a new opening if you key in a dimension it will place the opening that dimension from the start point of the wall (the wall segment currently hovering over), hopefully speeding up the process of adding openings.

I would also like to provide dimensions from the "start point" of the wall to any openings which update dynamically when the opening is moved by the user.

Inside each opening I would like to indicate the opening size and door or window type (ie. 4050XO, 2020PIC, 3068, etc...) but I don't see an easy way to insert simple text into the model.

Once you have the floor plan put together with the layout tool, you simply hit the "Generate" icon and the plugin will then automatically generate all of the walls (framing, openings, insulation, sheathing, siding, gypsum, baseboard and moulding) and optionally insert doors and windows into all of the openings. 

As the plugin matures, the plan is to provide more options for window and door options (mullions, wood vs. vinyl, dynamic components etc...) as well as increased options for wall cladding (siding, brick, cultured stone, stucco , wainscoting, pre-cast concrete accents, quoins, etc...)

Perhaps my vision is too ambitious?

Each wall segment (Ext/Int wall) will have two ends or corners.  The possible configurations for the wall ends/corners will be:

The ability to easily switch from 1A to 1B or 2A to 2B should be integrated into the plugin, at least from a framing standpoint.

I've slowly been formulating my plan of attack for this plugin.  Rather than jump right into it as I did with the truss plugin I've decided to take a step back and fully explore all the suggestions I have received.

I'm firmly convinced that I need to start with a 2D layout tool first that allows one to layout the floor plan (location of walls, door and windows) before I extrude/generate it into its final 3D shape.

One will be able to add, modify and delete doors and windows in each wall segment. 

Essentially each wall segment will have its own database associated with it that stores all of the wall properties as well as all of the opening properties.

I've been putting together the algorithms for the studs and for adding in openings.  Corner treatment is of importance to me and making sure that the studs are framed properly (as one would build it) is also of prime importance.

Version 1.9.8c
- Enabled option for F436 vs. F844 flat washers for timber trusses (in the materials tab within the global settings).

Hi Nathaniel,

Haven't been here for a while so I read through the later postings. I'd followed you on Kickstarter and was disappointed when you didn't reach the goal. I'd like to offer a couple of thoughts:

1) Your neck: My old eyes required me to move my head to see all of the screen, giving me stiff necks. I recently started using an ErgoMart Limbo desktop stand for my monitor. It has the bottom of the monitor resting on my desktop, allowing me to have all of the screen in focus without moving my head.

2) How I use the truss plugin: I was new to SU and couldn't understand how to create roofs, particularly since the pitch will be critical for us. So I just used your plugin to create the roofs, mostly ignoring the trusses. I suspect that many new SU users have the same problem. How about a separate plugin for beginners? It could create the roof surfaces, leaving the necessary information for the full program to create the trusses (or just hidden until the full program is purchased). The quick roof surfaces program could be your mass market product.

Best wishes,

I have given this some thought but I'm still not sure how I implement it.  Thank you for bringing up this concept.  I will explore it further.

Version 1.9.8 - 09.04.2017
- Added queen post and howe timber trusses with bolts and metal plates.

View model here:

Timber trusses haven't seemed to garner much interest or feedback but I do feel like it is a worthwhile contribution to the plugin.

There is more to be done with the engineering side but I will move on to something else unless customer feedback brings me back to it.

The big prize right now is the straight skeleton implementation.  I have been mulling this one over for at least a year now.

The truss yard now has 23 different truss types/profiles:

Bolts and plates are now complete for the Queen and Howe Timber Truss types:

Please feel free to test out the web dialog at the link above.

Now all that remains is to bring the javascript code into the ruby.
