Foundation Plugin

This is kind of what I have in mind for the rebar for a top step:
Note the typical 3" clearance for the very top bar. Also note how the other top bar extends beyond the step by 12". I can provide another parameter that allows the user to specify the length of this lap/extension.
I apologize that the dimensions are so small in the image, I should have increased the text size to make it more readable.
The bottom step and double step would be similar. Thoughts or a different rebar configuration?
-
For the drain pipe with a step I'm looking at three possible ways to model the vertical transition:
The first model just follows the concrete step and makes a vertical jump.
The second model transitions with a couple of 45 degree elbows.
The third makes a more gradual transition with 16" of lead in before beginning the slope.
Which is the preferred way to model the drain pipe?

Version 1.3.9 - 08.30.2019
- Added an option for additional horizontal bars in the draw and edit menus for polyline stemwall foundations.
Now we just need a few more options that will allow for vertical bars.
-
Version 1.3.9b - 08.31.2019
- Added an option for vertical bars in the draw and edit menus for polyline stemwall foundations.
View model here:
The top of the vertical rebar is 3" below the top of the stemwall and extends into the footing by half the footing depth.
These various foundation assemblies are starting to rival the wall and truss plugins assemblies in complexity and details, exciting stuff.
I still need to work on a module that will allow for brick ledges on stemwalls as well as another module for adding in windows and doors. A CMU option would also be nice. No matter how hard I work on this stuff it always seems like there is more, its a moving target I guess.

Version 1.3.9c - 09.01.2019
- Enabled rebar for stemwall steps (top step only).
- Added an option for additional horizontal and vertical bars in the draw and edit menus for stemwall steps.
I rolled the revision a little early since I noticed there was a bug in the edit function for stemwall steps. If you've recently installed 1.3.9b, I would highly recommend updating to this latest version.
I just need to work out the rebar for the other two step configurations and then rebar is complete.
I will then attack anchor bolts next, then the drain pipe and then the FPSF insulation. I will probably leave the vents disabled for now or at least until someone gives me more feedback on how they would like to see this configured.
The nice thing with the rebar is that you still have the option to install top and/or bottom bar with or without the horizontal bar, so lots of design permutations.

Version 1.3.9d - 09.02.2019
- Enabled rebar for stemwall steps (bottom step and double step).
Rebar was a bit a of a pain especially the double step, the rest of the advanced options should be relatively simple comparatively.

First look at stemwall steps with drain pipe:
View model here:
I don't know why but just looking at this model makes me very happy. I guess I've been trying to do this sort of thing with foundations since I began programming the foundation plugin about three years ago and I am now finally arriving at a viable solution.
Note, that the hide edges option will hide the concrete lines at the end of each assembly and the entire foundation will appear as monolithic. I have not enabled this option in this model because I want to show the three different steps types distinctly.

First look at that stemwall steps with FPSF insulation:
Not sure if an additional piece of insulation should be added at the actual step, any thoughts on that?

-
Version 1.4.0 - 09.02.2019
- Enabled drain pipe for stemwall steps.
- Enabled FPSF insulation for stemwall steps.
- Enabled anchor bolts for stemwall steps.
The stemwall step tool is complete.
Again the only thing missing is the vents option (which I have disabled for now). I will give this some more thought and address it as soon as I have a practical solution.
The next item of business is the interior bearing tool/module which will allow for linear interior bearing assemblies (ie. post-and-beam, stud wall, CMU etc...) I'm very familiar with the first two systems however I'm not so familiar with how CMU interior bearings are typically constructed. Any information would be helpful.
This next module is very simple and I hope to complete it within 3-4 days. Then back to the quest for the holy grail of the Truss plugin... Complex Roofs.

Now a video demonstrating the polyline stemwall, interior bearing and step tool all working together would be interesting.

There has been some call to provide a CMU option for the polyline stemwall module. In order to represent CMU my intent was to not alter the model but just apply the appropriate material/texture as I am doing with the Wall plugin. However this method only really works with linear sections of walls (at least for the faces parallel to the Z plane):
As you can see from the image/model the vertical faces come out just fine however the horizontal faces are a bit of a mess. I really don't want to change up the way I'm modeling the stemwall itself (ie. breaking it into linear segments) so the solution might be to simply provide a more generic material for the horizontal faces without any of the brick interior design, mortar lines etc... thoughts? It would look not quite as realistic when looking at the top of the CMU wall but it also wouldn't appear as confusing as the result shown here.

Medeek Live Training: Session 1
Scheduled time is 11:00 PST
This is my first attempt at live streaming so hopefully things go smoothly but I'm sure it will be a bit of a learning experience. The primary topics covered will be the recent additions to the foundation plugin however I am willing to open it up to other questions about all of the other plugins.
-
This bi-directional pattern (even though not as realistic) seems to be a decent compromise and provided the segments of the polyline stemwall are orthogonal and in length increments that are multiples of 24" the texture works:
-
First look at a CMU polyline stemwall:
Note that the callout includes the number of CMU block calculated per the volume of the stemwall and the standard block size (16" x 8" x stemwidth). For now the nominal depth and height of the CMU block is hard coded to these typical values found in North American construction but I will probably provide some parameters in the global settings where these values can be customized.
The horizontal face texture I'm using only really works well for standard CMU block sizes and if the walls are orthogonal and in 2' length increments. I don't have a work around yet to deal with exceptions. I will give this some additional thought and come up with a better solution.
Now all I need to do is enable CMU for the stemwall step tool and then I'll roll a new release.
This update is a direct result of discussions had in today's training session, thank-you to everyone who participated and providing feedback which will directly impact the plugins' development.
-
Version 1.4.2 - 09.05.2019
- Enabled CMU blocks for polyline stemwall foundations.
- Enabled CMU blocks for stemwall steps.
** NOTE **
If you have previously installed the plugin and are upgrading to this latest version in order to utilize the new CMU feature please do the following action once you have installed Version 1.4.2:
1.) Click on the global settings tab.
2.) Click on the Layers tab within the Global Settings.This action will initialize the “CMU Layer” for future use. New installations of the plugin will automatically initialize the new layer when they enable the layers options for the first time. This action is only required for those users upgrading their plugin installation.

I'm interested in putting the new polyline stemwall tool through its paces. If you have a fairly complex foundation plan that you think I should try and model please email me a PDF of it.
-
Version 1.4.2 - 09.06.2019
- Fixed a bug with the rebar in closed loop stemwall assemblies.
Critical bug fix, I strongly suggest upgrading to this version of the plugin.

I've moved to the complex roof development but there are still a number of glaring holes in the foundation plugin. To get a better feel for how well it would work I modeled up a foundation for a residence that I did some local engineering for a couple of years ago:
View model here:

Really the only manual edits that were required was the blockouts for the garage doors and the footings for the porch roofs. The following list summarizes some areas that need further development:
1.) Need some sort of option for garage door block outs.
2.) Need the ability to create holes in stemwalls (crawl access, windows, doors)
3.) Add interior footings to regular slabs, similar to the interior footing tool for slab-on-grade foundations.
4.) Stemwall opening tool should also remove any conflicting rebar (boolean subtraction).
5.) Still need to add the tool for a simple polyline footing (ie. porch footing shown). The workaround is to create a stemwall and then manually delete the stemwall leaving the footing portion.I'm also thinking about creating a material list table that summarizes quantities, similar to the legend I generate in the electrical plugin.
So much to do, I really need a whole team of developers to get everything done I need to do.
What would be interesting to know is how much time it would take to manually model up the equivalent geometry, also bear in mind that there would be no parametrics available so if you need to adjust something it would require considerably more time and effort to make that change. With the plugin if I need to adjust something like anchor bolt spacing I simply edit the assembly with a right click and the changes are instantaneous.
Modeling time was about 30 minutes. Most of that time was transcribing dimensions from a large, crumpled set of paper plans. The rest of the time was largely spent on fiddling with the garage door block outs and then trimming the rebar back. As it stands now I do think the plugin offers some significant time savings but there is much that remains to be done.
