3D Truss Models
-
I have a question or request for our Mac/Apple users. Has anyone tried using the plugin on a Mac. I don't have access to a Mac so I have no way of testing the plugin to see if it actually might work on this platform. If someone would be willing to test it out for me I have no problem in setting them up a permanent license and sending them the full version of the plugin, this would help me out a lot.
I've had to take a bit of a break from my coding, too much local work to process and never enough time in the day to get everything done.
As Juju suggests, I am going to try and figure out a better positioning mechanism before I start adding more truss types or additional features. This is the biggest thing holding the plugin back right now.

Version 1.0.7 - 11.03.2015
Trusses can now be positioned and sized via three mouse clicks, with the option for manual overide in the dialog windows.
The number of trusses is now based on the spacing and building length.
Floor trusses with top chord bearing now are positioned properly.Hopefully I haven't broken the metric inputs with the latest revision. I will test further tonight but so far its looking really good.
-
Version 1.0.7 took a while to pop out. The big improvement is the ability to click with the mouse at three corners and place the truss set without any additional rotating or translating.
In literally seconds I can now put a floor and a roof on 4 walls using the truss plugin and the Homebuilder plugin:
Of course the gable walls are not quite right but you get the idea. I may have slightly misunderestimated (a word created by GW Bush) SketchUp and what one can do with it.
The biggest hurdle was to learn how to create and properly set up a "tool" within the API. Adding different truss types is much more fun than working through that mess.
I'm also thinking it might be useful to have an option to put sheathing on the roof and/or floor?
I'm also looking for a good plugin that does stemwall and slab on grade foundations, if anyone has recommendations please advise. I may use my own plugin for my own practice in order to quickly mock up certain structures and provide visuals. With the right tools I think SketchUp can be a very effective and quick turnaround platform

thanks!

Version 1.0.8 - 11.04.2015
- Added Weyerhauser TJI
I-joists: 110, 210, 230, 360, 560, 560D. - Rim joist option enabled for TJI floor joists.
Only a rectangular configuration is available currently. If I can figure out how to code a polygon version of this that would be much more impressive (ie. pick the points that define the perimeter of the foundation and the plugin generates the complete floor layout).
This is straying a bit from trusses but I figured if I'm going to include floor trusses I might as well make floor joists available as well, just a small bit of code to get there.
- Added Weyerhauser TJI

I have tested a few version of the trial on mac running Yosemite...
PM me if you have specific questions or want me to test the latest version...

haha--where's my comment? I was thinking of saying: add truss joist and solid lumber (as the floor trusses wouldn't be used on a lower floor like that). Then I thought you had enough to do! So I didn't post. Good work!
After years and years I still cannot get the programmer for another app I use to add engineered lumber options.

I'm considering adding the following advanced options to roof trusses:
1.) Sheathing
2.) Fascia
3.) Rake Board (Gable Overhang)
4.) Outlookers (Structural vs. Non- Structural, Horizontal vs. Vertical)
5.) Vent Blocks
6.) Gable End Trusses (Already in progress: Dropped top chord and structural variants)This would then provide a fairly complete roof framing solution.
For floor trusses (adv. options):
1.) Sheathing
2.) Gable End Floor Truss (Ladders)
3.) Ribbon BoardFor floor joists [TJI and dimensional lumber] (advanced options):
1.) Sheathing
2.) Midspan blocking at user selected bearing points.
3.) Sill Plate (for floor framing on top of concrete foundations)Please suggest other options that might be handy to have.

I thought about multi-ply girder trusses but I think for now it is not too hard for the user to simply create another instance of the truss component and manually stack them up to create double or triple ply trusses.
Another interesting thought I had is what would it take to codify an algorithm for creating a typical dormer:
However, this may be a bit ambitious at this point but I think it could be done.
-
In my neck of the woods we don't typically use dimensional lumber alot for floor framing anymore. Most of what I see is I-Joist products with LVL or LSL rimboard.
For those that still use dimensional lumber what is the common practice for the rim joists? I'm assuming that it is the same as the rest of the joists in the floor (ie. 2x8, 2x10 or 2x12).
-
We use both--particularly for the first floor over a crawl space, lumber can be economical. The rim joist is the same.
-
Version 1.0.9 - 11.05.2015
- Added separate toolbar icons for floor trusses and joists.
- Created separate submenu items under the Medeek Truss Plugin Extension for roof and floor trusses.
The main menu was getting a bit cluttered and not so user friendly so I split it out into "Roof" and "Floor", hopefully this makes more sense.

As I've been contemplating adding gambrel attic trusses to the truss plugin I've had to give some thought to what constitutes a good gambrel design. I've looked into this before but my conclusion is that no matter the lower and upper pitch of the roof a good looking design seems to be always achievable if the lower and upper legs of the roof are more or less equal in the length. To that end I've devised a simple spreadsheet calculator that will quickly throw out the numbers and display a graphic of the gambrel profile:
I'm not saying this is a hard and fast rule but it seems to give decent results. Minor variations (ie. L1 not equal to L2) are generally okay but if one leg is significantly longer than the other the gambrel profile becomes distorted.
The math to come up with this equality and generate the coordinates of the overall roof height and the pitch break is rather interesting and for those mathematically inclined is given below. Note that the equation ends up being a quadratic equation with the positive root extraneous:
-
I'm working on the advanced options for roof trusses and I'm looking at the fascia board. I've come up with three different configurations for the fascia that I've seen in practice and in the architectural books that I have.
Which method of the three below do you prefer? or is there another configuration that I have missed?
Note that I am only interested in the sub fascia if there are additional trim boards that is up to the architect or designer.
-
I prefer 1 and 2
I would take it a bit further or leave it simple, those that want more detail can use a number of paid plugins or free ones to route fascia profiles. but for doing fascia those plugins don't take in to account the subtleties of "following" a fascia path. certain sides and corners and what not are done quite differently with the same styling.
But one of my most common fascia combos ranges from 1x8 with a 1x4 added to it's face or I might even taller up to 10" or maybe 12" with 6 or 8" facing it.
up to you... you've already created quite a product.
-
I think I will include the option for either of the 3 variants since it isn't too much more to code and I'm getting quite a mixed reaction from different builders and designers. I guess everyone has there preferred method.
Another quite common fascia treatment is to use a 2x6 sub fascia with a 1x8 finish fascia (primed spruce or cedar).
However, I am mostly interested in the sub fascia and then I'll leave it up to the designer/architect to dress it up further as needed.
I'm trying to make the roof framing as easy as possible and basic structural items such as trusses, fascia, outlookers are all automated, then the designer can concentrate on the finish work (ie. ridge caps, trim fascia, barge boards, cupolas).

I've noticed that the admins have moved this board to a new location. Along that same line of thinking perhaps it is not appropriate that I discuss the day-to-day development of this plugin in the forums. I'm not entirely sure of the protocol on this since this is new territory for me. I will probably continue to field questions on this board related to the posts made thus far but if you would like to closely follow the development of this plugin please email or PM me.
-
I for one welcome seeing your comments re the plugin development and wouldn't want you to put this behind closed doors so to speak. Was the topic originally in the general forum and so has been moved more appropriately into the plugin area? Keeo it coming.

I would like the freedom to post links to other forums or resources as I see fit and this may not fall in line with the terms of service of this forums and others. I will not be bringing the development and its discussion behind closed doors, just to separate venue that I can have more control over and not be limited in the direction I may want to take the conversation.
I will continue to post major updates to this thread until someone tells me otherwise but for the daily development I will posting to my own personal blog or forum.
