Foundation Plugin
-
Version 1.2.4 - 06.26.2019
- Enabled the "Edit SOG Assembly" function/menu for rectangular slab-on-grade foundations.
-
Version 1.2.4b - 06.27.2019
- Corrected the code for raising and logging exceptions.
-
Version 1.2.5 - 06.29.2019
- Enabled the "Edit SOG Assembly" function/menu for polygon slab-on-grade foundations.
- Enabled the "Edit SOG Outline" function for polygon slab-on-grade foundations.
The ability to edit the outline of polygon shaped foundation is fairly important not only for this plugin but also for the complex roof module of the Truss plugin. I will be moving back to the Truss plugin this next week to continue my work on the complex roof module.

Tutorial 2: Editing Slab-on-Grade Foundations
-
Version 1.2.5b - 07.01.2019
- Enabled the "Edit Slab Assembly" function/menu for rectangular slab foundations.
- Enabled the "Edit Slab Assembly" function/menu for polygon slab foundations.
- Enabled the "Edit Slab Outline" function for polygon slab foundations.
-
Version 1.2.6 - 07.03.2019
- Enabled the "Edit Stemwall Assembly" function/menu for rectangular stemwall foundations.
- Enabled the "Edit Stemwall Assembly" function/menu for polygon stemwall foundations.
- Enabled the "Edit Stemwall Outline" function for polygon stemwall foundations.
All of the current features of the foundation plugin are now fully parametric. However, I do need to introduce a new system for handling stepped foundations and internal strip footings for both slab-on-grade and stemwall foundations.
-
The absence of a interior footing module for the slab-on-grade type foundation is very frustrating for me and I am sure for a lot of other users as well.
With that being said I've decided to put my thinking cap on again and give this issue some further thought. Based on what I have so far for foundations and looking at some other foundation examples I think the following parameters should be sufficient to fully define an interior (thickened slab footing):
Basic Options:
Footing Width
Footing Depth
Slope Angle
Slope Start: Yes/No
Slope End: Yes/No
Vertical Drop: default is zero
Reinforcement: Yes/No
Anchor Bolts: Yes/NoReinf. Options:
Ftg. Bar Dia:
Ftg. Bar Qty: 1,2,3,4,6Anchor Bolt Options:
Anchor Bolt Length: 10,12,14 (in.)
Anchor Bolt Dia.: 1/2 or 5/8"
Washer 2X2, 3X3
Bolt O/C Spacing
Sill Plate Thickness:
End Distance:The vertical drop option is the 6" dimension in the image below:
The interior footing module will be quite similar to the window and door module in the Wall plugin. It will allow the user to add, delete, move or edit any interior footing within the SOG. Unlike the current system (only one interior footing possible), the user will be able to create as many footing as they like, criss-crossing the slab in any direction at any angle. Once this feature is in place the slab-on-grade foundation will be much more versatile and hopefully much more capable of modeling real life (complex) foundations.
Please let me know if there are any other parameters or options that I might be missing from this list.
-
First look at the interior footing toolbar:
This toolbar will allow the user to add, delete, edit or modify interior footings within stemwall, slab-on-grade or slab foundations.
-
I will also be adding in a toolbar for working with brick ledges on slab-on-grade and stemwall foundations.
This will enable the user to add a brick ledge to any edge of a foundation, and also edit or delete the brick ledges. Currently brick ledges are only available with stemwall foundations and if enabled applies the brick ledge to the entire foundation outline.

Version 1.2.7 - 07.05.2019
- Added the Interior Footings toolbar and icons.
- Added the Brick Ledges toolbar and icons.
- Enabled a resync function in the License tab of the Global Settings for license renewals.
Within the License tab if you click on the license exp. date the plugin will then resync with the server and update your license exp. date accordingly. This is a resolution to the issue some users have recently had when renewing their license.
Previously the user had to remove their serial number and then re-enter it in order for the plugin to update itself with the new license expiration date.

Looking at adding in an option for a sub-base layer for slabs and slab-on-grade foundations:
Let me know if there are any specific requirements that you might have.
The only two parameters I have for this are the depth and the material.
-
Are you looking to add several other layers such insulation and surface finishes ie. screed in the future?
-
Moisture barrier?
-
Being that it is the weekend of the 4th I was quite surprised at all of the feedback on my previous post, thank-you for taking the time to respond and provide valuable feedback and information.
It seems that slab insulation is also a feature that I should also add to the mix. Most details I've seen shown it directly below the slab between the subbase and concrete:
Note that many details I've seen show the slab insulation wrapping down around the footing or at least dropping down along its vertical side to the bottom of the footing. However, to model the slab insulation in this way would be very computationally expensive (in other words a big pain in the butt) and require some rather elaborate code.
What I've shown is a slightly simplified version which I can easily achieve using some very simple boolean addition and subtraction.
The updated list of parameters is now:
Slab Insulation: Yes/No
Slab Insul. Thickness: Default to 2"Subbase: Yes/No
Subbase Thickness: Default to 4" or 6"
Subbase Material: Default "medeek_gravel", user can choose from custom material libraryI've also had quite a few request for poly. I've never been a big fan of modeling non-solid geometry (ie. 2D films, vapor barriers etc...) In my opinion the SQFT callout for the foundation is enough information for the designer to know how much poly is needed for the foundation if they want to apply it below the slab (plus some waste factor). I'll have to give this some more thought.

First look at a rectangular slab-on-grade with slab insulation and subbase material installed.
Now I just need to jump into the polgyon module and enable the same feature for a polygon/face outlined slab-on-grade and then we can roll this new feature out.
When I get a bit more time I will also add in the volume of the subbase material (CY) into the stats tab (attribute library) which can then be picked up by the estimator module and this information will also be part of the spreadsheet (Excel/CSV) output.
Note to other developers:
As I further develop these plugins I am including a stats table in the attribute library of each assembly I create. This information is exposed and can be utilized by anyone, including other plugins. For instance for slab-on-grade foundations I provide the number of anchor bolts, the lineal feet of rebar, the area of the slab, and the volume of the concrete. If there are any questions about any of the entries in this table and what each number means I will be more than happy to dive into the details with you.

Version 1.2.8 - 07.07.2019
- Added slab insulation and subbase options for rectangular slab-on-grade foundations
- Added slab insulation and subbase options for polygon slab-on-grade foundations
- Added a subbase layer in the Global Settings under the "Layers" tab.
Please note that the new interior footings module and the brick ledges module are both under construction. The current toolbars and icons for these modules are currently non-functional.
Both modules are actually quite complicated so my best calculation is about a week's worth of programming for each in order to complete them.
The FPSF option must be toggled on to enable under slab insulation. However, you now have the option to enable or disable perimeter insulation within the FPSF options.
-
Version 1.2.9 - 07.08.2019
- Added a Custom Material Library/Manager in the Materials tab of the Global Settings.
- Enabled custom materials for the subbase material in the HTML edit menus for slab-on-grade foundations.
I've had some conversations about providing formwork for the various foundations. This is not a high priority right now but at some point I may decide to add in this advanced option.
-
First look at a slab-on-grade (rectangular) foundation with multiple interior footings:
Note that this feature (interior footing module) allows for an unlimited amount of interior footings in any orientation and with each footing being customizable to its own specifications.
As shown in the image above this new feature also works with the subbase and slab insulation options.
Now I just need to work on the edit, move and delete functions for the interior footings.
-
This image demonstrates the vertical drop option/parameter along with various rebar configurations:
The footing to the far right is a typical 12" deep shallow footing with two bars.
The two central footings are 18" deep (4" slab) with a 10" vertical drop. When you specify a qty. of four or six bars the plugin will arrange the bars top and bottom as shown otherwise the bars will be positioned at the bottom of the footing (with a 3" ground clearance).
Note that all of the footings shown have a slope of 45 deg. however this can also be customized to any angle.
-
Working in 3D is a bit different, and poses some additional challenges, when compared with designing in a 2D environment.
Slab-on-Grade interior footings are an excellent example of this type of problem. In a 3D environment you are usually wanting to work on your model looking down at it rather than looking up at it. Unless you have modified the transparency of concrete material you are typically unable to view the interior footings you have created.
To remedy this problem I have created a hidden layer (normally hidden) that is toggled on when you go to add, edit, delete or move an interior footing. This layer not only contains the outline of each footing but also the label assigned to each by the plugin:
This layer can always be toggled manually by the user, but I have also setup the various tools to toggle it on and off during appropriate actions.
