Version 0.9.1 - 07.29.2025 - Updated the draw and edit menus for HVAC appliances. - Added the following brands and associated models into the HVAC appliance built-in library: Bryant, Rheem

Some Youtube viewers of this video reached out and told me that they had more equipment than could reasonably fit within such a small structure. I agree, maybe a 16'x12' space is a bit cramped for anyone, especially if you are also using it for a content creation studio. This is where the parametrics of the extensions come in real handy: https://3dwarehouse.sketchup.com/embed/aa7589c0-5dde-498d-ba91-ba73e1a68791?token=YhzP4g4wwgE=&binaryName=s21

Per customer request I will add in an LSL option for the framing very shortly: I'm using the updated LSL texture I created for the Floor plugin, but I still feel like it is a bit dull or dark compared to my previous texture (OSB). It could be a bit more vibrant or saturated. I will need to spend some more time on this. Weyerhaeuser sells their Timberstrand line of LSL framing and studs: https://www.weyerhaeuser.com/woodproducts/engineered-lumber/timberstrand-lsl/timberstrand-lsl-framing-lumber/timberstrand-lsl-wall-framing-studs/ However, I would always worry about water damage. What happens if the LSL gets wet? We all know what happens to OSB, and plywood is a much more robust product in comparison. Standard lumber seems like a much more resilient choice when it comes to potential water damage, but I could be wrong.

Version 4.0.7 - 07.20.2025 - Enabled the polyline draw mode for all wall justification options: Front, Center, Back, Sheathing. Tutorial 72 - Wall Justification (7:16 min.) I've wrestled with this issue since 2019 and up until now I have never been able to come up with a simple and satisfactory solution which allowed for the polyline draw mode. However, after giving it some additional thought this morning after responding to some suggestions by a power user I realized that I already had the solution in hand (from the recently released corner connection tool - Version 3.9.8). I only had to implement it and after a few more hours of testing and refining the logic I think we finally have a workable and robust solution for justified walls. Thank-you guys for hounding me on certain issues. Sometimes it takes a while before the solution reveals itself to me but eventually it usually does, I just have to put my thinking cap on a few times. Again, the squeaky wheel gets the grease.

Version 3.7.3 - 07.19.2025 - Enabled square cut rafter tails for gable rafter roofs.

Version 4.0.4c - 07.15.2025 - Added the following Simpson Strong-Tie holdowns to the wall, column and shearwall modules: HDUE3, HDUE5, HDUE7, HDUE9, HDUE13, HDUE17. Looks like Simpson added this new replacement for the HDU holdown in May of this year. I just noticed this morning so I added them in. https://www.youtube.com/watch?v=L-pa7M1g7dM Note that these are low poly versions of the holdowns based directly off of the geometry provided on Simpson's website.

[b]Version 4.0.4b[/b] - 07.14.2025 - Added springfield plates to the post base and post cap libraries (for 3.5" and 4.0" pipe). - Added the following Simpson post caps to the post module: LLC35_35, LCC35_4, LCC45_35, LCC45_4, LCC525_35, LCC525_4, LCC6_35, LCC6_4, LCC7_35, LCC7_4. If I'm going to add in this new "pipe" post then it stands to reason that I also add some appropriate bases and caps to match.

Version 4.0.4 - 07.13.2025 - Added the following steel post types to the post module: Round (HSS), Pipe (NPS). I'm not sure why I never added a "pipe" option in before, I guess no one ever asked until now. I will need to add more sizes but I now have the most commonly used sizes from 3" to 6" DIA.

After three weeks of non-stop coding I needed a break so I spent the day at the track (walking, I’m too old to run anymore) and then spent the evening digging up docs on Bryant furnaces. Surprisingly the dimensional data is quite accurate and thorough, here is the result: hvac_su050_8001493×1058 170 KB Six actual models added, but really there are only three sizes (17.5, 21, 24). I’ve been giving the calculations more thought and if I am able to incorporate that into the plugin then the BTUs, and other specs on these furnaces will also come in handy. I will probably need to create some sort of database or flat text file that has all the pertinent data on each furnace and the ability for the user to enter in custom furnaces and other appliances. I always find that doing some low level modeling has an almost therapeutic effect. Maybe SketchUp is just such an fun to use and intuitive modeling environment, either way I find it to be a great way to relax and unwind. All of the assets (furnaces, AC units, heat pumps etc...) will be part of the HVAC plugin and I think will be a great resource for anyone doing any sort of 3D modeling regardless of their platform. I'm basically doing the heavy lifting for you so you don't have to spend countless hours modeling off the shelf parts and products.

Version 0.9.0 - 07.10.2025 Created the Medeek HVAC Plugin, utilizing SketchUp’s Ruby API. Added tools to create ductwork, fittings, and HVAC appliances (AC, furnaces, and heat pumps). The BETA version is out, you can now download the trial version here: http://design.medeek.com/calculator/sketchup/medeek_hvac_ext.rbz Please be advised this is the very first release of the extension and there will be many fires to put out.

I’ve added a manufacturer parameter to the appliances menus since the number of part numbers is going to be so large I think it only makes sense to break these drop down boxes up a bit by “type” and “manufacturer”. There will also be a “generic” option for those parts/appliances that do not have a manufacturer’s logo affixed. hvac_su049_8001580×945 171 KB Modeling these various HVAC appliances is a bit tedious since I first have to find somewhat detailed literature or documentation so I can at least get them dimensionally accurate. Some of the features modeled are my best guesses based on images found online since not everything is specifically dimensioned within the manufacturer’s documentation. I also try to keep the models fairly low poly but typically there is not more than one or two of these appliances within a given model (for residential projects), so I am not as concerned as I am with HVAC fittings.

The following toolbar will be added for HVAC Appliances: The HVAC Appliance tool will be for adding AC units, furnaces, fans, VAV’s, boilers etc… Essentially any preconfigured HVAC equipment that is not duct work. The will be simple stand alone assemblies that one can reposition using the native tools.

Oval, round and rectangular are now up and running:

The next few days will be spent checking and double checking that the transition algorithms are robust and can handle all of the adjustments that get thrown at them. Overall they aren't too complicated, however when you start adding in offsets and rotations things can change very quickly. This morning I started with offsets and size differences for a RECT-RECT transition, which is by far the simplest of all the transition permutations. There are three different duct profiles which then yield six different possible combinations at any given transition, and each one needs to be tested and checked: RECT-RECT RND-RND OVAL-OVAL RECT-RND RECT-OVAL RND-OVAL (The text labels shown are just my temporary debugging markers so that I can track my points) Adding a rotation to a duct segment is probably going to be the worst case scenario in all of this, but I'm sure I can figure it out eventually.
