- Face mount hangers added for solid sawn floor joists.

LUS26
LUS28
LUS210 (this hanger used by both 2x10 and 2x12 joists) -
Version 2.0.3c- 10.14.2017
- Added Red Built Red-I
I-joists: 45, 65, 90, 90H, 90HS.
- Added Red Built Red-I
-
Version 2.0.3d - 2017.10.15
- Added PinkWood SAFEjoists I-joists: PKI 10, PKI 20, PKI 23, PKI 35Plus, PKI 40, PKI 50.
This I-joist manufacturer has a pink protective coating on the ends. The purpose of the end coating is to protect the joist against moisture penetration.
In addition, PinkWood offers Class A and Class B Fire Rated joists often referred to as "SAFEJoists". These joists are protected with an intumescent Fire Rated Coating, and have tan colored coating on the web.
Manufactured in Calgary, Alberta, Canada.
Now that I've got things configured correctly it is quite easy for me to add in new manufacturers and their entire series of I-joists. If you are interested in seeing a particular brand added to the plugin please feel free to contact me.

Thanks for the note on those trusses. Always looking for reasonable 1 hr. 2 hr. assemblies.

I drop the price and sales decrease rather than increase, this just doesn't make any sense.
Some sort of reverse psychology I guess.
p.s. I moved the price up slightly to $20.00 and $15.00 for the renewal and sales are picking up again.

A request today for the barrel vault truss. I had been working on the algorithm for this truss type about 18 months ago but the lack of interest caused me to stop. Below is a matrix of potential configurations:
If anyone has some shop drawings for this truss type that they are willing to share I would be grateful.
I will try and knock this one out next week. I will probably utilize an html/svg UI since the look and feel of this truss type will be important to the designer (barrel height and barrel width).

I've got some direction on how to deal with engineering for beams and joists, not high on the priority list right now but I've been giving it some thought:
Intersecting Faces or Edges
In the model below you can see that the I-joist is supported or touches three separate faces (surfaces). I am trying to figure out a way to code an algorithm that lets me know all of the bearing points along a beam o…
SketchUp Community (forums.sketchup.com)
At first gathering the geometric information from the model seemed the most challenging aspect of this problem but after giving it more thought, dealing with multi-span beams with various distributed and point loads is also not a trivial problem. My current beam calculator is very limited in this respect and can only handle very simple loading on a single span.
And yet even with the simplicity of the span and loading the logic and calculations required is fairly substantial. The output of the beam calculator will attest to this.
To properly analyze a multi-span beam with complex loading requires some magic from my engineering texts (ie. matrix analysis). Since beams and joists are one dimensional as compared with trusses (two dimensional) the math is not nearly as cumbersome but it should prove to be a bit of a challenge.

The updated truss menu:
-
Version 2.0.4 - 10.21.2017
- Added Parallel Chord (vaulted) truss type, configurations: (2/2, 4/4, 6/6).
I will still need to enable structural outlookers and plates for this truss type, but everything else should be there:
- Roof Cladding
- Roof Sheathing
- Gable Wall Cladding
- Gable Wall Sheathing
- Ceiling Gypsum
- Ridge Cap
etc...

I have been hoping for the parallel chord truss. Just great.
Thanks...! -
All you have to do is ask.
This truss type is relatively close to the scissor truss so I was able to bring it together fairly quickly. If there is anything I'm missing on this truss type please let me know. I can also add the 8/8 and 10/10 configuration if requested

Version 2.0.4b - Added the 8/8 configuration:

People have often asked why there is always a guy shown in various screen shots for the plugins next to the truss, foundation or building displayed. The reason for the person in the picture is to give the geometry some sense of scale. I've also received comments as to why the "old guy"? Some have even complained about it. Each release of SketchUp features a new default person for that release. The 2015 release featured an older gentleman. Since most of my audience is architects and designers who are the predominantly of the male gender perhaps it would be more fitting to use a female model to indicate the scale?
Conclusion: The problem with the female model is she is too distracting. The audience will naturally focus on the model and not on the product I am selling which is architectural modeling software (BIM). The model should only function as a yard stick and should remain secondary to the structure or building component displayed. Bottom line I won't be switching to a female model anytime soon.
Another point worth noting is that a well designed truss or roof is already a thing of beauty, no further marketing gimmicks required.

Spoken like a true engineer!

I've been slowing chewing away at the straight skeleton algorithm and still working out some of the kinks, there is a lot of logic dealing with how the rafters intersect various valleys and ridges. I will continue to hammer away at this over the next couple of weeks and hopefully have something to release by the end of November or sooner.
On a slightly different note I've been examining Vali Architects Instant Roof plugin and looking at how it generates gutters. Is this something that people would be interested in seeing added to the plugin?
I don't think it would be too much of a stretch to add this feature in.
I would probably start with the standard 5" K-style gutter where one could fine tune the dimensions within the global settings.
I'm assuming one would just want to draw this a surface and not a solid?
-
I think you'd have to use as a surface to keep the polycount down. VA Roof plugin is very good and I use it especially for quickly adding the materials and features like gutters. The gutters and caps are not all that accurate,but OK for an overall building model. For ogee gutters I use my own geometry with Followme etc. I do not worry about having it open on top as it hardly affects the appearance of most views to the model and the solid shape is easier to work with. In sections, you might prefer it open for realism. I also add downspouts.
BTW I don't often use the actual roof forms of InstantRoof because I don't seem to have roof designs that work well. There's always something unusual about the roofs. I figure (since you go for accurate framing) your plugin has also solved the issue of accurate placement of the roof planes in relation to the plate height, which is my problem with most roof plugins.
