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.

medeek

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.

medeek

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.

How is this integrated with the rest of the Foundation--or does it just create an isolated component from which you position copies into the model?

This tool creates separate footing assemblies within the model. It is separate from the rest of any other foundation assemblies.

These footing assemblies can be edited and moved anywhere within the model.

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.

medeek

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:

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.

Version 1.4.5b - 09.11.2019

Added the option to place a double mat of rebar within a spread footing (top & bottom).

Note that the top mat is identical in size and spacing as the bottom mat.

thanks for the efforts!

the toolbars for your extensions are becoming rather elaborate and taking up a bit of toolbar / screen space, any chance you could implement a single initiation button/icon instead and have a secondary open when the primary has been triggered, much like Fredo does some of his extensions?

@medeek said:

Hmmm, you might be on to something with this.

I agree that the amount of toolbars has multiplied quite rapidly as I keep adding more features to each plugin, it does take up quite a bit of screen real estate now.

Thank you for the continued efforts Nathan! I see the toolbars are steadily increasing, any chance you can look into the request / suggestion above?

I am looking into this further. Again, not entirely sure on the best possible solution but I will see if I can either consolidate or provide some other system.

medeek

First look at the blockout tool and its results:

Now I just need to have it trim out the rebar and remove anchor bolts that are in the way.

I'm also including an option to have it remove anchor bolts or not remove them in the case that for some reason you don't want to remove anchor bolts that clash with the opening.

I'm going to assume that designer would always want to trim the rebar out and the insulation, but I could also be mistaken on this and might need to provide a couple more options that allow for toggling this behaviour on and off for each blockout.

The edit and delete functions seem to be stable, I just need to get on the move tool and make it work similar to the move tool for openings in the Wall plugin.

The blockout label is on the hidden layer and toggles on and off automatically with the blockout tools.

medeek

First look at rebar trimming and anchor bolt removal:

Now I just need to get the move function working correctly and I think this new set of tools is ready for prime time.

And yes, when you insert blockouts the plugin is correctly calculating the decreased volume of concrete or CMU blocks for the stemwall.

medeek

CMU stemwall with blockouts:

I think this plugin is finally beginning to coalesce into a legitimate extension.

Still, a few more items remain that need attention but I will need to put those on the back burner for a couple of months while I turn my attention to the truss and wall plugins. The biggest items are:

1.) Doors and Windows in foundation walls.
2.) Internal footings for basic slabs (not slab-on-grade)
3.) Finish integrating the Medeek Estimator with this plugin
4.) Engineering (footing calcs primarily), see example here: http://design.medeek.com/resources/footing/SQUAREFOOTING_CALCULATOR.pdf
5.) Retaining walls with engineering
6.) Additional interior bearing types
7.) Move/Stretch tool for SOG and Stemwall foundations

These are the big items that come to mind right now. The actual list is probably four times this list in size. Please let me know what additional features or improvements you would like to see.

Version 1.4.6 - 09.14.2019

Enabled the "Draw Blockout" tool for polyline stemwalls.
Enabled the "Edit Blockout" tool for polyline stemwalls.
Enabled the "Move Blockout" tool for polyline stemwalls.
Enabled the "Delete Blockout" tool for polyline stemwalls.

I will put out a short tutorial demonstrating this new tool even though it is mostly self explanatory.

One to thing to note is that this tool only works for the "new" polyline stemwalls. I'm not sure yet what I'm going to do with the old stemwall tool. Basically everything you can do with old tool you can achieve with the new polyline tool (with the exception of joist pockets). I will need to give this some more thought.

Tutorial 7 - Blockouts in Polyline Stemwalls (8:35 min.)

Unfortunately, I forgot to demonstrate the CMU option with the blockouts, so I will leave that up to the user to try that out for themselves.

If you are using stemwall foundations at all this newest feature is critical in my opinion. Manually creating blockouts in your stemwalls renders the parametric ability of the plugin mute, hence this latest addition was necessary.
