Medeek Floor
-
In many cases when you introduce a stairwell opening into a floor like this it will be along the perimeter of the floor assembly as shown. In these cases it is simpler to create your floor perimeter with the opening in mind:
Note, in order to create the additional gable truss (2x6 ply) I first changed my ply width to 5.5" then copied the gable truss at the interior of the stair well, then pasted it in place in the root of the model and then edited the floor assembly back to the typical 3.5" ply width. Alternatively one could simply frame this small pony wall with the Wall plugin (ie. conventional framing) just as easily.
I'm not exactly sure how the trusses would work where the LVL beam/header is positioned at the start of the stairwell, obviously we would need some kind of header at that location.
Here is a link to the model for those who are interested in examining this floor truss example in more detail:

Thank-you to all those who are sending in bug reports. Please keep sending those in, they are very helpful and I am able to track down and put out the little fires that much more quickly.
If you think you have encountered a bug, turn on the Ruby Console in SketchUp, then duplicate the behavior and then send me any error codes generated with other pertinent details. I will do my best to remedy all bugs that are detected and reported.

Version 1.1.3 - 01.13.2026
- Enabled custom overhangs for sheathing.
- Added a "Remove Overhang" parameter to selectively control the sheathing overhang.
Update per customer request.
This feature is identical to the overhang feature included with steel decks and will allow the user to set an overhang and then selectively assign specific edges which do not have the overhang enabled.
Tutorial #20 explains how this feature works:

Version 1.1.7b - 02.25.2026
- Fixed a bug with the ceiling gypsum option.
Previously if you set the ceiling inset parameter to zero the logic would try to apply this zero offset and would throw an error and then abort the draw process. I guess I automatically assumed a non-zero inset (ie. 3.5 or 5.5 inches) and did not test it with a zero inset, so I never caught this specific state.
Shout out to @ArtisanTony for finding this one for me. I probably would never have found out since I'm always using an inset when I turn on the gypsum, I don't think I've ever used a zero inset.
Keep sending in those bug reports, it is greatly appreciated. This extension isn't very old so I know there are still a few more small fires to put out, the trick of course is finding them all.

Version 1.1.8 - 02.26.2026
- Added AcuJoist I-Joists: ACJ 40, ACJ 60, ACJ 80.
I think that gets us to nine different I-Joist manufacturers in the US and Canada. I think Lebel and Eacom (both out of Canada) also make some I-Joist products, but I don't believe they have as much market share as the companies listed below:
- Weyerhaeuser Trus Joist
- Boise Cascade BCI Joists
- LP SolidStart I-Joists
- Red Built Red-I
I-Joists - PinkWood SAFEjoists and PKjoists I-Joists
- Roseburg RFPI I-Joists
- Nordic I-Joists
- PWT PWI I-Joists
- AcuJoist I-Joists
