Version 1.3.4 - 08.01.2019
- Added the Stemwall Foundation toolbar and icons.
- Enabled the "Draw Polyline Stemwall" tool.
- Enabled footing offsets and mitering within the draw polyline stemwall tool/menu.

Note that the ability to edit polyline stemwalls is not yet active.  I am putting this out a bit earlier than I normally would so that users can give me additional feedback on the functionality and features.

Also note that to terminate your point selection process you depress the "Down Arrow" and not the Enter or Return key.  I would like to change this to the Enter key but I'm not quite there yet.

The polyline tool will only draw the concrete currently, all other additional options like rebar, anchor bolts, insulation, vents and joist pockets are currently not available.
Footing offsets and mitering is now stable:

When the foundation outline is a closed loop the polyline tool will automatically close the stemwall foundation and draw it as if it were a closed polygon as shown above.
First look at the output of the new stemwall module:

In this particular situation you would probably just use the polygon stemwall tool for the outer perimeter since there are no steps in the foundation but I think the model demonstrates the idea.

I should probably change the label to something like WALL or STEM, I'll give this some further consideration.

What I really like about this new module is that it is so much more flexible than a simple polygon or rectangular outline.  Once I add the step and interior bearing tools this one is going to be a game changer.
First look at the draw menu for the polyline stemwalls:

Only the Basic Options appear when all of the other options are toggled off.

Similar to the Wall plugin it will allow the user to draw a polyline section of foundation and then continue on and keep drawing more sections, updating settings as required.

Note the inclusion of the hide edges option in the updated menu.

Other options like brick ledges, joist pockets and openings will be on a per edge basis, so they do not appear in this menu or in the edit menu.

The basic template is now in place however I am still considering how to best terminate the tool while the user is picking points.  My thought is to terminate the picking process by having the user hit the Enter key.  Unlike the polygon method the user is not needing to return to the start point so there is no natural detection of when the user wants to terminate their picking of points.

Any thoughts on what the most intuitive method of handling this should be?
In the other forum the following question was asked:

Does the polyline stemwall tool automatically hide the butt edges of adjoining sections? In your render with the pony walls, the lines appear hidden, but in the screenshot above that they are clearly visible.

My response:

Technically, each of the stemwall segments are separate assemblies (groups) so they are not welded together (ie. one solid).

However, I do have a few tricks up my sleeve in this regard. I can enable an option which will hide the edges of the solid so that the foundation can appear to be all one solid. I'm already doing this sort of thing with the Wall plugin, however it is on a global settings scale. I think it makes more sense to set this up on a per segment basis since there may be times where you do not want to hide the edges of a particular segment. I will need to give this some further thought.

Personally I don't find this to be a very important concern since rendering eliminates these unwanted edges, however I can still see that there might be an issue when generating elevation or plan views.
I've been giving this new module some serious thought and I am hoping to get it right from the outset.  All of the menus will be advanced HTML menus and everything will be parametric and available in imperial or metric units.

Similar to the slab-on-grade foundation the polyline stemwall foundation will allow the user to specify brick ledges on a per edge/segment basis.  I will also setup a tool for joist pockets using the same template as the brick ledge tool.

The user will be able to toggle a polyline assembly left or right.  This will switch the direction of the interior/exterior which affects things like brick ledges, joist pockets, insulation and anchor bolts.

This new module is practically an entire rewrite of the original stemwall module (even though I will leave the original stemwall tools intact as they are), and will probably take me another week or two to complete.  As I'm digging into it, there is a significant amount of code to complete.

If you see a feature that you think I am missing or I should change something up please feel free to voice your opinion, now is the time to influence the direction of this development.
Sometimes you may have a situation like the one shown in the image below:

To allow for this I will include a start angle and end angle parameter so the ends of the polyline assembly can be adjusted to account for various intersections with other foundation elements.

I will also include a start and end footing offset so that the footing can be offset (neg or pos) from the stemwall at the ends.  Note that this offset dimension will always be measured perpendicular to the end face as shown.
Running my conceptual tools through their paces this morning.  Here is another example of a fairly complex multi-step stemwall foundation:

Note that the three different types of possible steps are represented in this model.

View model here:

Also note that I will be providing for the ability to offset the footing from the end of the stemwall (both positive or negative) so that the user/designer can easily butt up against other foundation walls (ie. create T  or cross intersections, corner).

As I was working on this initial model/concept a couple of days ago my teenage son noticed that I spent most of the afternoon constructing the model and then adjusting it.  He thought that it was funny that I spent a couple of hours mucking around with the model and actually pointed that out to me.  Even though most of my time was spent pondering the model (rather than creating the model), he did have a point; it should only take a designer a few minutes to generate this type of foundation, and it should be relatively easy to do.  This is the goal of this new module, quick and effortless.

In the model you will notice that I added cripple/pony walls to bring the floor elevation all to the same height.  These walls were generated with the wall plugin in less than 60 secs.

First look at the new Stemwall toolbar:

The three functions/tools are:

- Draw Polyline Stemwall
- Draw Interior Bearing
- Draw Stemwall Step

I've got quite a few icons now for this plugin and I'm still not entirely sold on my choice of icons/images for these toolbars but this is what I have for now.  I did try to create some 3D icons but at the resolution available for the toolbars it is very hard to create a legible 3D icon.

With regards to the step tool I also need some more information on how best to handle the footing rebar and the stemwall rebar for a step in the foundation.  I've examined a few details online as well as some of my own but additional feedback would be helpful.
With the new polyline and step tools (stemwall foundation) you will be able to create a foundation like this:

Each polyline segment will be able to be edited similar to the how you edit the outline of a stemwall or slab-on-grade foundation outline now.

Similar to the wall plugin the drawing direction will be counter clockwise in order to face the exterior of the stemwall to the outside.  This becomes important for anchor bolts, insulation, brick ledge, and joist pockets.

Each segment will be an independent assembly (group) that the user can simply move around (laterally and vertically) with the native tools.
