Medeek Floor

First look at a Nucor/Vulcraft (K Series) steel floor truss (top chord bearing):

Currently these are defined by 13 parameters but I may need an additional four in order to specify a top chord extension and the bottom chord extension on both ends.

another consideration are vierendeel openings for ducts... etc

Various configurations and example usages of top-bottom and bottom-top for open web (Redbuilt) and steel trusses (K Series):

medeek

Version 0.9.9t - 11.19.2024

Added the "Open Web" floor family (RedBuilt: Red-L, Red-M, Red-S, Red-M, Red-H).
Added the following TriForce Open Joists: OJ3-14, OJ4-14, OJ3-16, OJ4-16.

Version 0.9.9u - 11.23.2024

Added the "CFS" floor family: ClarkDietrich, JoistRite and TotalJoist.
Added additional logic for non-standard joist sizes for Open Joists (TriForce).
Addressed some minor bugs with metal bracing and other advanced options for top chord bearing trusses (Open Web and Steel).
Added a built-in steel material option for rim joists.

Let me know on any other floor framing system(s) that I should add.

Version 0.9.9v - 11.24.2024

Added a "Web Shield" option for PinkWood (PKI) I-Joists.
Fixed multiple bugs with the floor preset module.

Version 0.9.9x - 12.01.2024

Fixed a bug with the SUBTRACT_JOIST feature.
Updated the algorithm for large span Open Joist floors.

Rather than insert a fictitious joist size that does not actually exist I decided to insert two short joist products back to back. This seems to be the typical way to handle large span floors with this product (similar examples are given in the product literature). This update was also by customer request.

The update to the SUBTRACT_JOIST feature is a critical update and I highly recommend updating to this latest version if you are using that functionality. Since the boolean subtraction of the joists happens before the final floor assembly is created I had to account for the pre-transformation of the joist geometry and include this within the subtraction method.

as a note though, it's also common to stagger the shorter joist sets to get more purchase on the supporting beam, certainly with plain wood or lam joists. thus one set of joists is shift to one side or the other of the opposing joists so they each extend to the full width of the beam.

probably not something you need to code though. if i needed to represent this, i would just create separate floor sections and nest them - so leave it as is now.

The floor opening tool and the MPC wood trusses are still pending so I really don't want to call this Version 1.0.0 but I also really need to get some bug fixes out the door and some other minor updates and I've run out of letters in the alphabet. In the next couple of weeks I'm hoping to devote all of my time to these two big items and see if we can actually knock them out this time.

I'll be the first to admit that I am spread a bit thin with all of these plugins. I've been bouncing back and forth between the Wall and the Truss plugins for the last couple of months but now the Floor plugin needs my attention.

Version 1.0.1 - 05.18.2025

Added floor openings with fully customizable headers.
Added the floor openings toolbar with the following five items: Draw, Move, Edit, Regen and Delete.

Tutorial 22 - Floor Openings (13:59 min.)

I've been giving the feedback I received thus far on the new opening tool some serious thought and after further testing I can see that adjusting the header extensions to reach out and grab the correct joist is probably the biggest bottle neck in the process, if you can call it that.

Below is an example of a six sided L-shaped opening in a floor. It has three headers and three "trimmers". Note that headers run perpendicular to the joists however the opening tool really makes no distinction between headers and trimmers, they all have the same ten parameters.

I had to make five entries to adjust the headers to meet the I-Joists as shown. Really not that difficult but somewhat time consuming and tedious in my opinion. The solution to this problem could be to have the plugin somehow detect the nearest joist and auto-extend to it. However, I feel that such an algorithm would be overly complicated and probably not very robust.

The other option would be to create a "Header Stretch" tool that allow the user to simply mouse over the header, select one end or the other and then stretch it to the desired location. This tool would be very similar to the "Wall Stretch" tool that is part of the Wall plugin. Rather than navigating through the labyrinth of menus one could simply adjust each end with only three mouse clicks.

Again, I have my work cut out for me.

I've also realized that it is not readily apparent to the user which header is which. I may need to incorporate some sort of labeling option that will assist with this.

also, consider in most practices the headers perpendicular to the joists, and some trimmers are doubled to ensure strength on the spans and avoid "soggy" floors.

The Floor Opening toolbar will now contain a sixth tool called “Stretch Header” which will allow the user to stretch the opening headers in a more intuitive fashion:

I’m not really wanting to add more icons to my already bloated toolbars but I feel like this will be a very worthwhile tool and it will almost certainly makes everyone’s life a little easier when it comes to these openings.

I am also working on enabling double and triple ply headers, so much to do and never enough time to accomplish it all it seems.
