      Version 1.1.2 - 05.06.2017

      • Added "Circle Segments" option within the global settings, rebar and mesh polygon counts can now be controlled.

      http://design.medeek.com/resources/images/foundation_su42_800.jpg

      In this example I set the segment number to "5".

      The global setting circle segment number will default to 24.

              In our Passivhaus builds, this is the preferred foundation type for several reasons.

              I think you would be surprised at the EPS insulation thickness under-slab... up to 14". Of course, this varies considerably with different climate zones. (We are in Quebec with winters where -40° is not unexpected)

              There are modular slab insulation systems for FPSF. Iso-Slab is a Quebec-based one: http://www.iso-slab.com. Their web-site has technical info on these systems that may be of interest to you.

                I've had a request for adding the option of insulation around a slab on grade, in short a frost protected shallow foundation (FPSF).

                This should not be too hard to add in. There are a number of resources online I will study to come up with the most standard configuration as possible.

                Are there any particular things anyone would like to see with regards to FPSF insulation.

                The typical installation per the 2015 IRC:

                FPSF.jpg

                The NAHB has an upated publication at this link:

                403 Forbidden

                favicon

                (liteform.com)

                XPS vs. EPS? Not that this will affect the plugin but I am curious which is preferred by those who commonly install these types of systems.

                  An FPSF with 2" foam insulation along the wall and vertically. 2.5" foam insulation at the corners with the following horizontal dimensions:

                  A = 12"
                  B = 24"
                  C = 40"

                  http://design.medeek.com/resources/images/foundation_su45_800.jpg

                  The rectangle foundation is easy, the polygon shaped foundation will be more challenging.

                  One thing to note is that if dimensions A or B exceed 24" then some form of protection for the horizontal insulation is required (ie. conc. slab, pavement, PT plywood).

                    An irregular shaped FPSF, note the 135 deg. corners. Once this angle becomes greater than 135 degrees I would probably just treat it the same as a straight wall.

                          Working on the square/rectangle spread footing tool:

                          Post Footing

                          I will start with wood posts as an option with the following sub-options for the wood post:

                          Post Size: 4x4, 4x6, 6x6, 6x8, 8x8
                          Post Height (in.)
                          Post Base: None, ABA, ABU, ABW, CBSQ
                          Post Cap: None, CCQ, ECCQ
                          Post Rotation: 0, 90, 180, 270

                          I also plan on having the option for steel posts with the following sub-options:

                          Post Size: HSS4x4x1/2, HSS4x4x3/8, HSS 4x4x1/4, HSS3x3x3/8 etc... (round and square tube)
                          Post Height (in.)
                          Base Plate Size (in.) - square shape L x L
                          Base Plate Thickness (in.)
                          Base Plate Hole Dia. (in.): 1/4, 3/8, 1/2, 5/8 (4 bolts per baseplate)
                          Vert. Offset (in.) - for non-shrink grout
                          Post Cap: Not sure what to do with this yet.
                          Post Rotation: 0, 90, 180, 270

                          I've been contemplating using the Simpson Strong-Tie post caps and bases as provide in the warehouse but I'm worried that the polygon count is too high. I may have to generate my own dumbed down versions.

                          My 13 year old daughter asked, "What is this for? What good is it?". I replied, "It is good for all sorts of things, just like a Thneed." Then I proceeded to discuss decks, porches, carports etc...

                              Can you do that with the option of putting it (as a vertical component only) on the inside of the foundation wall? It may be of use in climates that isn't as cold and you have the option of putting it either inside or outside of the foundation plinth wall.

                              Save the Earth, it's the only planet with chocolate.

                                I can add another option to insulate the vertical interior face of the stemwall/foundation wall.

                                  Working through the issues of the polygon FPSF option has helped me understand better how to deal with adjacent walls in particular non-orthogonal walls and how best to calculate the geometry at their intersections.

                                  This has me primed for further development of the wall plugin, so even though this feature may not have much use for most of the client base it still have served a major purpose in educating me.

                                  With the tool function I am able to create lines to show preview geometry however I am wondering if there is a way to show a dimension (beyond showing the numerical value at the bottom of the SketchUp window).

                                    An octagon slab on grade (FPSF). Note that the angle of the corners is 225 degrees, any less and the corner treatment would go away.

                                    http://design.medeek.com/resources/images/foundation_su53_800.jpg

                                    Clarification on the angles:

                                    Any corner with an inside angle greater than 135 degrees will not receive corner treatment.

                                      I've had some discussion with other SketchUp users about developing the plugin for commercial use. Should I require that the user have PRO installed? A number of registered users of the plugin do not use it for commercial use, I would rather keep it open to all users but it would be easier to develop within PRO with its Boolean functions.

                                        Added "FPSF" option to polygon stemwall foundations.

                                        Now I've thoroughly beaten the FPSF option to death, the only thing I might add in later is a global setting to change the insulation color to pink, blue or white.

                                          Else the works created would need to be "signed off" by a professional, in which case the lines get blurred and the commercial application / gain with the use of the extension arises...

                                            Now I've thoroughly beaten the FPSF option to death, the only thing I might add in later is a global setting to change the insulation color to pink, blue or white.

                                            Is there an option for underslab insulation? What is the range of insulation thickness available?
