      Interior footings are so variable. You might not have these all figured out long after the others, because they are only needed in certain structural requirements, which are figured out later in the process. Then there are pads for posts.

      This looks like a great start! Foundations can become very complex, but getting the basic perimeter in would be nice, especially where it can be pushed and pulled for modifications later--letting you have a simple base for your preliminary model. When I think of my projects it's seems each one has one special condition after another.

        The ability to go back in and easily edit a foundation without having to recreate it will be crucial to the success of this plugin.

        Version 1.0.1 - 07.05.2016

        • Enabled partial width interior footings for slab on grade foundation.
        • Addressed minor bugs with UI geometry menu: Interior footing depth can now be specified.

        Interior footings quickly complicate things but a well designed html UI should clarify things greatly and make it much more intuitive. That will be the next objective.

          how about the ability to exclude area (-s), eg. island areas?

          if I were to be interested by this I would probably only use it for slabs without plinth walls (have Profile Builder 2 for this), etc. - thus ability to add sub-base layers and specify thicknesses would help.

          EDIT:

          Also the ability to add specified layers on top of the slab would help automate 3D modeling.

          Then to be able to specify the TOC or FFL as origin from which to build the configuration would be great!

            Currently the top of the slab is the origin. What do you mean by layers on top of the slab?

              Certainly, juju, I'd assumed that a Medeek plugin would be moving towards all sorts of options: plinth wall, no plinth wall, raised floor,retaining wall, basement, garage (floating) slab...

                If the exclusion area is simply a hole in the slab then it is probably easiest just to push/pull a hole in the slab. However, if the exclusion area is a large opening with footings required at the perimeter then that is a different matter. It might look something like this:

                Note how the opening bisects the interior footing, which does potentially complicate any algorithm that would generate the hole and perimeter footing. I will have to give this some more thought...

                  Typical stem wall foundation (crawlspace) with interior strip footing and floor beam. This is what is built locally around these parts (Ocean Shores, Washington):

                    Nice.

                    If the girder is only supporting the floor, around here we use isolated post and piers without the connecting footing.

                      I've seen the footings done both ways. Locally the majority of homes are built very close to the beach directly on sand with a high water table that fluctuates with the tides. The strip footing helps prevent shifting of the piers and posts and uneven settlement.

                      Out of curiosity what are the typical dimensions of your piers? and posts?

                      Some contractors locally like to use 4x4 posts and some default to 4x6 with a floor beam size of 4X8 fairly typical. When I do the engineering I will check the floor beams and posts as well as the soil pressure at the footing but I rarely encounter a problem.

                            Would it be easier for a user to pick a number of points to describe a polygon or to have a tool that allows one to select an existing face as that polygon? I also need a stemwall tool that allows one to create single walls (curved or linear) since there are times where you do not want to create a closed polygon outline.

                              When the user selects a type B footing (stemwall foundation) a keyway is inserted between the stemwall and footing:

                                  I'm trying to determine which is the preferred method of blocking out a stemwall foundation for garage doors where a slab will be poured in the garage. I've seen it done both ways. Option 1 does not typically block all of the stemwall out and seems to be more common in locations where the frostline is deeper (24" or deeper). Option 2 completely blocks out the stemwall at the garage door and then a thicken edge is poured where the slab meets the footing at the garage door. From a structural point of view which is the better method and also from a construction point of view what are the pros and cons?

                                  Option 1:

                                    I should point out I've also seen a sort of a combination of the two options where the blockout does not extend to the footing but a thickened edge is employed at the slab/door interface and the thickened edge is typically 2x the slab thickness, or called out as a minimum dimension of 8".

                                    Option 3:

                                      That looks like a better one. Then there's someone I am working with now who wants the slab floating and not resting or tied to the foundation at all. Preference could depend on soils.

                                        If there is enough room between the footing and the slab I could see how one could omit the stemwall and have a layer of gravel, sand, soil between the slab and the footing at the opening. I have never seen a slab poured that way at the garage door opening but it doesn't mean it can't be done. I supposed one could even go so far as omit the footing across the opening as well but from a structural standpoint I would highly discourage that, much better to tie the building foundation together at the perimeter with regard to lateral loads.

                                          Option 1 is what I have used many times. Never the others. Frost depth 2 to 3 feet typically.

                                            The blockout methods seem to be all over the board, I've even talked with some of my engineering friends and the response is mixed there as well. I guess I just need to provide the option for any of these three configurations within the plugin. Sometimes I feel that I get bogged down in the details but I hope some of this level of detail is appreciated.

                                            The other issue I'm having with slabs within garage spaces is the slope of the slab. I'm trying to determine if is worth trying to incorporate a slope into the slab as it would actually be poured. As far as I know there is not a minimum slope specified for garage floors in the IRC 2015 or earlier only this fairly general statement:

                                            [highlight=#ffffcf:1d83tmnb]The area of the floor used for parking of automobiles or other vehicles shall be sloped to facilitate the movement of liquids to a drain or toward the main vehicle entry doorway.[/highlight:1d83tmnb]

                                            Typically the garage slope is 1/8" per foot or 1:96, how critical is this to you the user of the plugin? Flat would be easier to program but then your blocked out entries on the side of a garage would be only theoretical.
