Version 1.8.7 - 03.26.2017
- Added energy/raised heels for double howe truss (3 variant: wedge, slider and vertical w/ strut).
- Metal plate connectors now enabled for double howe trusses.

Back to updating all the truss types with metal plates, raised heels and all other advanced options.

Version 1.0.9 - 03.25.2017
- Added slab foundation type (rectangular outline only).
- Enabled full and partial width interior thickened slab footings.

Version 1.0.8 - 03.23.2017
- Added crawlspace vent option to stemwall foundations.
- Added a "Materials" tab within the global settings; Auto material assigment (colors and textures) is now an option.
- Enabled materials for all foundation types.
- Added a joist pocket option for stemwall foundations.

I've been putting off the joist pocket feature for a while but figured I could spend my Friday night and knock it out.  I doubt it will get much use except for certain builders in the State of Oregon.

The options for the joist pocket option are:

1.)  Pocket Width
2.)  Pocket Height
3.)  Pocket Depth (into the stemwall)
4.)  Pocket Spacing (default is 16" o/c, but can be set to any value)

If you use joist pockets with either the brick ledge feature or the crawlspace vents you need to realize that the geometry must be such that the various item don't clash.  For example the stemwall must be thick enough for a brick ledge and the typical 2.25" depth of the joist pocket. 

With vents and pocket joists there must be enough vertical clearance between the two otherwise the header will be too thin for the overlying floor joist.  One solution to this problem is to have the vents only on the front and back walls while the joist pockets are on the left and right walls.

The number of options and inputs is now a bit mind boggling and the code is also at a new level of complexity.  Taking all of this to a polygon shaped foundation will be a challenge but that is where it needs to go next.

The vent module seems to be working fairly well:

If you set the top distance to zero the vents are right up to the sill plate:

Notice the top bar is clashing with the vent cutouts. 

The options for the crawlspace vents (if this option enabled) will be:

1.) Width (in.)
2.) Height (in.)
3.) Corner Distance (ft.)
4.) Top Fnd. Distance (in.)
5.) Max. Spacing (ft.)
6.) Location:  All Walls|Left/Right Walls|Front/Back Walls
7.) Vent Insert:  NONE|PLASTIC|METAL

The Max. spacing variable will determine whether to insert intermediate vents along the wall line.  The module will always place two vents per wall (if wall line selected), one at each corner and then equally space vents along wall line based on the Max. spacing variable.

I am currently working on the polygon and line tool for both stemwall and slab foundations.  I am finding it hard currently to get enough time to really push ahead quickly so I don't have an ETA on the release of these tools.

The ICC codes call out a minimum of a one vent within 3 feet of each corner.  It shouldn't be to much trouble to create the openings in the stemwall and place some vents:

For a rectangular building (4 sides) should I place 4 vents or 8 vents?  Provide only the openings or also provide a generic foundation vent (lightweight geometry?)

Moving an opening is actually very easy within SketchUp, when it comes to a solid wall like this.

What is the typical header thickness between the top of the vent hole and the top of foundation?

Vent size seems to be 16"x8" for most vents I've seen.

With regards to vents there are the cheap plastic ones you can get a Home Depot or Lowes and and then there are a whole ton of more expensive louvered metal manufacturers of vents and flood vents.

I agree, I've been talking to a few other contractors out there and most of them don't pay alot of attention to the orientation of the J-bolts into the concrete, they let the concrete set up a bit and then stab them in.

I'm adding in the custom materials, stemwall foundation below is an example:

I will need to roll another revision probably tomorrow to get this update out there.

Any additional thoughts on adding in vents and what is standard construction in your locale as well as what type/brand of foundation vents/inserts are used.

The cosmetic threads actually render quite nicely as does my rebar material/texture.  I just realized I have not added any custom materials into the foundation plugin.

As you can see from the image the orientation of the J-bolts is the same regardless of the wall, however it would not be a couple more lines of code to orient them all facing in or facing out or some other combination.  Curious how the contractors actually install these, is the orientation important

Version 1.0.7 - 03.19.2017
- Added 1/2" and 5/8" Dia. Anchor Bolt option to stemwall and slab on grade foundations.
- Anchor bolt lengths are nominal 10", 12" and 14", square washers are 2"x2" or 3"x3".

View model here:

The anchor bolt, washer and nut are three separate files that are loaded in as components.  Then the nut and washer components are inserted inside the bolt component and exploded so only the solid group(s) remain.  Its pretty amazing what you can do with a robust API and a little bit of Ruby code.

It took me most of today to figure out how to do all of this since I'm in uncharted territory but now that I've got it kind of figured out it opens up the possibility for a host of other things (holdowns, windows, doors, vents etc...) for this plugin and the others I'm working on.

The 1/2" and 5/8" anchor bolts, washers and some standard nuts.

I need some input from the foundation and truss plugin users. I've decided to pre-model certain things like Bolts, Nuts, Washers etc... With Nuts and Bolts I'm planning on using a cosmetic thread so that the polygon count is minimal. As I've been experimenting with the bolts and nuts I'm wondering if I should eliminate the 30 deg. bevel on the head of the bolt and nut, it looks nice but adds quite a bit of complexity and polygons to the model. Any thoughts on this?

You would sacrifice some realism for a smaller model...

I'm trying to determine if its easier to write a module that draws the anchor bolts or just bring in the component (pre-drawn).  I've never brought in a component before so something I need to explore further.  The other thing I feel is key is to make sure any of these minor components are modeled in such as way as to remain fairly lightweight within the model.  No one is going to want to use a feature that bogs down their overall model.  That is my one big gripe with using the 3D Warehouse models, the polygon count on most models is usually outrageous.

I've been reviewing my Todo list lately and it really hasn't shrunk much, if anything it has grown a bit as I've added some new features in the last month and more catching up needs to be done with various truss types. 

I only work on this project part time and on the weekends as much as possible, so my progress since September of 2016 has been quite slow (took a new job with the City of Ocean Shores).

Currently the Truss Plugin has seen the most development but I am also spread between the other separate plugins as well:

Medeek Wall Plugin
Medeek Structural Plugin
Medeek Foundation Plugin
Medeek Deck Plugin

The structural and wall plugins will be just as complex and involved as the Truss Plugin and will require a couple years of my full time attention to get where they need to go.

When I step back and look at everything I want to accomplish there is just no way, given my current situation, that I can achieve it.  It would be nice to also be able to hire some help in knocking out some of the coding, realistically there is only so many hours in a day and only so much one person can do.

I would really like to work full time on all of this as I see it has some serious potential and I'm also very excited about it but my previous attempt at using KickStarter to raise some working capital did not amount to much.

I was watching Shark Tank last night and I was thinking would this type of business even have a chance in that setting?  Anyhow, I am open to any ideas you might have in how to really blow this thing up and get it going.
