Version 1.1.0 - 04.14.2017
- Added polygon outline tool for slab-on-grade and slab.
- Enabled perimeter rebar, anchor bolts, and slab reinforcement for (polygon) slab-on-grade foundations.
- Enabled slab reinforcement for (polygon) slabs.

Version 1.1.1 - 04.23.2017
- Added polygon outline tool for stemwall foundation.
- Enabled perimeter rebar, anchor bolts, vents, and internal footings for (polygon) stemwall foundations.

The next improvement would be a web_diaolog input so that more than one internal footing can be specified at a time.

Using the rectangular floor primitives I was able to manually create the floor on the previous foundation in about 30 minutes:



If I create the polygon floor tool I will be able to accomplish the same thing in under 10 seconds.  The polygon floor tool in the truss plugin is next...

The trim tool in the Truss Plugin comes in quite handy when dealing with more complex foundation geometry:



For this foundation I used the stemwall (rectangle and polygon) function and the slab (polygon) function.  I had to trim the garage stemwall and also manually create the smaller interior post/beam assemblies.  I also adjusted the position of some of anchor bolts once I cut the doors into the garage stemwall.

Throwing a roof onto this foundation is fairly straightforward:

Recently I've received a number of requests for concrete columns to be added to the foundation plugin:



I'm still trying to figure out how to best add a concrete column module, I think it could gain some serious traction.  This would cater more to the industrial rather than the residential side.

I'll use ASDIP Concrete Software as a guide in establishing the various options to include:

Version 1.1.2 - 05.06.2017
- Added "Circle Segments" option within the global settings, rebar and mesh polygon counts can now be controlled.



In this example I set the segment number to "5".

The global setting circle segment number will default to 24.

Some common configurations of concrete columns:

Have you considered adding insulation? We're planning on using a Frost-Protected Shallow Foundation because of it's cost, our zone 6 location, and the rocks and ledge we know are there.

As the insulation thickness and extent vary with zone and occupied/unoccupied this has those two parameters, but is well-specified in the code. Here is an explanation with links: http://buildipedia.com/aec-pros/construction-materials-and-methods/slabs-for-colder-climates-part-1-the-how-and-why-of-frost-protected-shallow-foundations?print=1&tmpl=component.

Additional complexity would come with unoccupied slabs (e.g. garage, front porch, patio) contiguous to an occupied slab. Edge insulation would be an issue too.

If this is outside the bounds of your plans, please feel free to ignore it.

Up until now I have not considered adding insulation but it probably would not be too hard to add in.  I will do more research on FPSF. 

An FPSF with 2" foam insulation along the wall and vertically.  2.5" foam insulation at the corners with the following horizontal dimensions:


A = 12"
B = 24"
C = 40"





The rectangle foundation is easy, the polygon shaped foundation will be more challenging.

An irregular shaped FPSF, note the 135 deg. corners.  Once this angle becomes greater than 135 degrees I would probably just treat it the same as a straight wall.

Version 1.1.3 - 06.03.2017
- Added "FPSF" option to rectangular slab-on-grade foundations.
- Added an insulation layer in the global settings under the "Layers" tab.

- Added "FPSF" option to rectangular stemwall foundations.

Working on the square/rectangle spread footing tool:

I will start with wood posts as an option with the following sub-options for the wood post:

Post Size:  4x4, 4x6, 6x6, 6x8, 8x8
Post Height (in.)
Post Base:  None, ABA, ABU, ABW, CBSQ
Post Cap:  None, CCQ, ECCQ
Post Rotation:  0, 90, 180, 270

I also plan on having the option for steel posts with the following sub-options:

Post Size:  HSS4x4x1/2, HSS4x4x3/8, HSS 4x4x1/4, HSS3x3x3/8 etc...  (round and square tube)
Post Height (in.)
Base Plate Size (in.) - square shape L x L
Base Plate Thickness (in.)
Base Plate Hole Dia. (in.): 1/4, 3/8, 1/2, 5/8 (4 bolts per baseplate)
Vert. Offset (in.)  - for non-shrink grout
Post Cap:  Not sure what to do with this yet.
Post Rotation:  0, 90, 180, 270





I've been contemplating using the Simpson Strong-Tie post caps and bases as provide in the warehouse but I'm worried that the polygon count is too high.  I may have to generate my own dumbed down versions.

Thanks for the FPSF additions, I'm looking forward to working with it.
