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.

The top of the vertical rebar is 3" below the top of the stemwall and extends into the footing by half the footing depth.

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:

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.

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

https://youtu.be/asjVeOE6M3A

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.
Nathaniel P. Wilkerson, P.E.

Medeek

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.

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:

https://3dwarehouse.sketchup.com/model/7991f2ff-be4c-4835-8a88-18792bf6f699/Complex-Foundation-1

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.

Version 1.4.3 - 09.07.2019
- Enabled the "Draw Strip Footing" tool with the following advanced options: rebar, drain pipe.



Similar to the polyline stemwall tool you can create closed loop polylines (polygons) as well as simple linear sections of footing.

Similar to the polyline stemwall tool the point selection of the tool is terminated with the "DOWN" arrow key.

The horizontal bar option is shown in the menu but is currently not enabled.  I need to give this option some additional consideration before I make it live.

After working through the complex foundation on Friday, and having to manually create stemwall blockouts for garage doors I've come to the conclusion that a stemwall blockout tool is critical to the success of this plugin.

I guess I'm just a lazy 3D modeler, but even having to push/pull a blockout is too much work for me and then it ultimately breaks the parametrics of that particular stemwall assembly, so manual edits should be avoided whenever possible.

Yet another toolbar:



Like the Wall plugin the Foundation plugin is starting to collect quite a few toolbars, this will be the sixth toolbar for this plugin.  I'm starting to run out of screen real estate, I may have to do something about that, I'm not sure what yet.

The problem is that the plugins need to be able to do a lot of things, so there are a lot of tools and each operation/function needs its own icon or button to instigate it.  I've managed to wrap some functions into context menus but some operations are better presented as a direct icon in my opinion.

First look at some column footings (spread footings) with and without pedestals:



I've decided not to add the column portion into the Foundation plugin, that will be part of the Wall plugin.

I just need to add a bit of rebar into these assemblies and then I will roll a new version.

#170
Version 1.4.4 - 09.09.2019
- Enabled the "Draw Column Footing" tool with the following footing types: spread footing, spread footing w/ pier.
- Added transverse and longitudinal rebar for column footings.
- Added the Stemwall Blockout toolbar and icons.





The Draw Column Footing tool is the 4th icon on the main toolbar.

This is a really easy tool to use, I highly recommend upgrading to the latest version to take advantage of it.

The blockout toolbar has been added however these tools will not be functional until the next release.

With the pier option enabled I would be interested in adding in options for vertical rebar (with hooks) and possibly hoops, but I first would like some more feedback in this regard.

For concrete piers resting on a spread footing I was kind of thinking something along these lines for the rebar:



However, one would probably want the vertical bars to hook into the spread footing rather than terminate as shown.

Parameters might be something like:

Vertical Bars:  Yes/No
Vert. Bar Dia.:
Vert. Bar Qty.: 2,4,6,8

Hoop Bars: Yes/No
Hoop Bar Dia.:
Hoop Spacing:

Let's try to avoid taking it to this extreme though:

Probably something more along these lines:

If you look closely at the model you will notice that the texture/material on the vertical bars is a bit of a mess where they flare out to meet the spreading footing.  Special attention will be required to make sure the initial follow me operation is done on the X-Y plane and then the bars are rotated up into the vertical position.

Does this type of rebar detailing look useful?  Sometimes I need to use a bit of restraint so I don't take things to far, but if this is something that would find some utility I can add the additional rebar options in.

#173
Version 1.4.4b - 09.10.2019
- Added vertical and hoop rebar for column footings with round or square piers.





Sorry, useful or not, that pier rebar was just too tempting to pass on.  When you enable piers and rebar you are now presented with an additional section with options for vertical and hoop rebar within the pier.  Square piers are currently limited to two, four or eight vertical bars, round piers are limited to the following number of bars: 2, 4, 6, 8, 10, 12. 

If you need more than twelve vertical bars then you are probably not designing a residential structure. 

I'm not a concrete guy (haven't done a lot of reinforced concrete engineering, mostly lumber and timber), so this is kind of my best guess at what is appropriate for residential work.  If you need specific details changed up, please let me know.

Square pier with eight vertical bars:



I'm also thinking about adding in sonotube footings/piers (no spread footing) with an option for a bell shaped footing:

Nathaniel P. Wilkerson, P.E.

Medeek

Version 1.4.5 - 09.11.2019
- Added Sonotube footings to the "Draw Column Footing" tool.
- Added a flared "Bell" footing option for sonotube footings.
- Added vertical and hoop rebar for sonotube footings.



When you toggle the "bell" option on I have the vertical rebar bend 90 degrees as shown and extend to the perimeter of the bell (ground clearance maintained).

Sonotube footings without a bell option have vertical bar as shown.
