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/No

Reinf. Options:

Ftg. Bar Dia:
Ftg. Bar Qty: 1,2,3,4,6

Anchor 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.

As a celebration of the 4th of July and the full parameterization of the Foundation plugin I will be offering an incentive on new purchases or renewals of the Truss, Foundation or Wall plugins.

If you purchase or renew any of the BIM plugins on the 4th of July (tomorrow) you will be entitled to a complimentary license for the Medeek Electrical extension.  This promotion is only valid on the 4th of July.

I will be taking most of the day off tomorrow (finally) and eating some good food and watching some fireworks on the beach.

Happy 4th of July!

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.

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.

Tutorial 2: Editing Slab-on-Grade Foundations

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.

Version 1.2.4b - 06.27.2019
- Corrected the code for raising and logging exceptions.

Version 1.2.4 - 06.26.2019
- Enabled the "Edit SOG Assembly" function/menu for rectangular slab-on-grade foundations.

Version 1.1.2 - 06.25.2019
- Fixed an HTML/javascript bug with the wall edit menu (specific to Internet Explorer).
- Fixed an HTML/javascript bug in the General tab of the Global Settings (specific to Internet Explorer).

These two fixes were prompted by problems being encountered by users of SketchUp 2015.  I haven't quite decided yet but I will probably end support for SU 2015 and 2016 in the very near future as I have already done with the Truss plugin.  At some point the effort to maintain compatibility with older versions of SketchUp is no longer feasible or profitable.

If you are a registered or even trial version user of the plugin and still using SU 2015 or SU 2016, please contact me so that I can get a better feel for how many users are still requiring this compatibility.

With the recent post about the foundation plugin (adding in parametrics for slab on grade foundations) some people are asking "Why did you stop working on complex roofs and move back to the foundation plugin?".  As it turns out the algorithm or logic for editing the "polygon" outline of a complex roof or foundation is pretty much the same.  Since I have the overall code in place for a slab on grade foundation I am first implementing the polygon face edit tool with the foundation plugin then I will bring this code over to the Truss plugin and complex roofs.

First look at the new edit menu for slab on grade foundations:

Version 1.1.1 - 06.19.2019
- Corrected the code for raising and logging exceptions.

Version 2.4.8 - 06.16.2019
- Added a Soffit/Fascia tab to the Global Settings.



I've been developing this plugin now for almost 4 years.  Progress is steady but much yet remains to be done.  Once the complex and secondary roof modules are operational this plugin will begin to compete with the big dogs of architectural software (eg. Revit, Chief Architect etc...)  Its taken a while to get to this point with a few detours along the way but I'm getting very close to accomplishing the holy grail of the plugin which has always been the ability to handle complex roofs automatically.

Still trying to get the complex roof module up and running but every time I try and refocus some other fire comes along and pulls me sideways.  The soffit and fascia module introduced another block of parameters which need to be exposed in the global settings so users can set their default behavior, this is a relatively easy addition.  I will knock this one out sometime later this evening.

With the Wall plugin I also have a huge list of items but a couple which are actively being requested are stacked windows and a custom offset parameter for the stud spacing.  I really should hop back into the Wall plugin and try to address these before I get re-focused on the complex roof module.

The recent metric fix will be a welcome upgrade/resolution for many of you using metric templates.  Again, I apologize for not spending as much time as I would like on debugging the metric side of the house.  I will try to make a more concerted effort to check the metric side moving forward.

Version 2.4.7b - 06.14.2019
- Addressed a number of critical bug fixes for metric templates.

If you are working with metric units this update will address a number of issues that were not resolved when the edit function was added to various trusses and rafter roofs.  This is an essential upgrade.
