I am starting this new discussion thread as a fork from the Medeek Truss Plugin thread since the Medeek Floor extension will now become a stand alone extension/plugin.
Its icon(s) will be:
This new plugin will ultimately replace the floor joist/truss module currently found in the truss plugin.
Similar to the complex roof module the designer will be able to create any polygon shaped floor outline, and edit the shape by moving/adjusting the edges.
There will be a tool for creating and editing holes within the floor.
There will also be a tool for creating polygon shaped floor coverings (ie. carpet, tile, wood, pergo etc...) with an associated label and optional sqft callout. These floor coverings will be situated on top of the sub-floor and can be individually edited.
Eventually the floor assemblies will also be integrated with the estimating module currently found in the wall plugin (this will be moved to the Medeek Project extension in the near future).
There will also be an option for gypsum on the underside of the floor with a user editable offset (ie. 5.5 inches).
I have a few more ideas for this new extension but I would be interested in hearing what ideas you might have that would make this extension have even more utility for you and your workflow.
Per discussion and input this morning from a valued mentor/adviser I've added a few more items to the list:
1.) A tool for adding in mid-span blocking where the user can specify a location, extant and type of blocking.
2.) A blocking tool (also need this for the wall plugin) which will allow the user to create special blocking for point load conditions etc...
3.) An in-floor beam tool similar to the in-column wall tool of the wall plugin. The wall plugin already has a beam tool but this is for stand alone beams.
4.) Option for cavity insulation within the floor assembly, however an additional parameter which allows the control of the batt thickness since it may not be the same depth as the floor cavity.
5.) With the floor covering tool provide a vertical offset parameter. I may also set it up so that multiple layers are possible.
I've been thinking about this plugin some more as I've been occupied with upgrading the javascript/ruby interactions within the wall plugin.
Some floor framing plans are very simple, while others are considerably more complex.
I need to make the plugin as flexible as possible so it can accommodate the more complex floor variants.
One issue I'm trying to address is how to best handle floor plans that have floor joists running in different directions within a single floor plan/assembly.
My proposed solution is to limit the direction of the floor joists in any given assembly to one direction. Then to allow for a complex floor assemblies I will need a tool to suppress the rimboard along any given edge of the floor assembly. This will then allow for the butting up of floor assemblies next to each other to get the desired floor framing layout.
This particular edge tool will have three options for any given edge of the floor assembly: rimboard, no rimboard, or ledger.
First look at the main toolbar for the plugin:
(http://design.medeek.com/resources/images/floor_su_menu_active.jpg)
1.) Draw Floor
2.) Edit Floor
3.) Move Floor Edge
4.) Edit Rim Joist
5.) Engineering
6.) Global Settings
Most of these tools are fairly self explanatory, number 4 is probably the most interesting. I will allow the user to customize each rim joist per floor edge (if desired), or remove it entirely. This will come in useful where there are multiple floor assemblies abutted next to each other.
There will also be additional context menu tools (ie. regen floor assembly). One context menu tool I am thinking about adding in is a way to select a given edge as the starting point for the floor joists/trusses. This will allow the direction and spacing of the floor joists to be aligned to any edge along the floor outline.
There will need to be another completely separate toolbar and tools that deals specifically with holes cut into the floor.
Lots of little details to still work out and even though much of the code base can be recycled from the other plugins there is still a lot of work involved to produce a completely new plugin with the capabilities that I envision for this new architectural tool.
First look at the floor opening toolbar:
(https://aws1.discourse-cdn.com/sketchup/original/3X/d/3/d3ff1055d4f90c34514b85419d97d45bc7a40a5c.jpeg)
1.) Draw Floor Opening
2.) Move Floor Opening
3.) Edit Floor Opening
4.) Delete Floor Opening
First look at the floor covering toolbar:
(https://aws1.discourse-cdn.com/sketchup/original/3X/5/d/5db1e9dc6e5fe8956c4a6feff989f91d3485d755.jpeg)
1.) Draw Floor Covering
2.) Move Floor Covering
3.) Edit Floor Covering
4.) Delete Floor Covering
The colors are a little bright for me, I may have to subdue them a bit to get the right look.
First look at the floor beam toolbar:
(https://aws1.discourse-cdn.com/sketchup/original/3X/3/1/312cef67d5b618154b5af8058e5f69e4766d556d.jpeg)
1.) Draw Floor Beam
2.) Move Floor Beam
3.) Edit Floor Beam
4.) Delete Floor Beam
If the floor beams align with the joists/trusses things are fairly straightforward, however if the in-floor beams are perpendicular or oblique to the joists this becomes a bit more interesting.
I will have to give some serious thought to this module in order to make it as flexible as possible.
(https://woodaware.org/img/construction/Girders_(Beams).JPG)
So far this is a total of four toolbars. I may need one additional toolbar for misc. items such as mid-span blocking and/or a blocking tool, but I can address these items later once I have established the core functionality of the plugin.
Am I missing anything obvious?
For the floor covering module I think an option for 2 or 3 layers should be sufficient for most cases:
(https://aws1.discourse-cdn.com/sketchup/original/3X/4/a/4a41ca0ef58f7f4bdd80cf46aa3295eafdcdcd3d.jpeg)
In this case I am modeling/representing the carpet and its pad.
Tile floors usually require some time of cement board underlayment.
Pergo and hardwood floors may also have an underlayment of some type or another.
Openings cut in the floor assembly will also cut through the floor coverings if they intersect. This will allow for interior holes within a floor covering.
Development was paused on this extension at the beginning of March, I apologize for the delay in its initial BETA release. Development will begin in earnest again starting June 1st, with an estimated ETA of Sept. 1st.
Will tHIs plug-in be part of the BIM package?
Quote from: mrramsey on March 21, 2021, 08:42:21 AM
Will tHIs plug-in be part of the BIM package?
Yes, it will be the 4th plugin within the mdkBIM bundle.
I've finally wrapped up my recent move (Utah -> Missouri) and the dust is beginning to settle some. The next few weeks I will be working in earnest on the Floor plugin and try to get it put together and released before the end of the summer and prior to the upcoming SketchUp Basecamp.
Looks like I've got most of the basic Global Settings all put together now. Fairly basic to start with, I'm sure as this progresses it will diverge from the initial template quite a bit:
(https://aws1.discourse-cdn.com/sketchup/original/3X/2/a/2ad2b3ae78dbde67fc584e8e738f5c3a45577ab7.jpeg)
Progress is slow but steady.
Here is a first look at what the updated Floor plugin Layer tab in the Global Settings looks like:
(https://global.discourse-cdn.com/sketchup/original/3X/3/e/3e9cbb4cf6617304851b627b79254a65724501c4.jpeg)
I just realized that the Layer Control in the Project plugin does not have a control in place for the new Floor plugin, there is always more to do.
The edit menu and draw menu are pretty much done now, just a few more tweaks and error checking and we might be able to start creating our first real floors with this thing:
(https://global.discourse-cdn.com/sketchup/optimized/3X/2/0/20c16d0501736d7be6258e6ce72a539eaf42e7cd_2_228x500.jpeg)
I was going to include the blocking as an advanced option but after some further thought it seemed like it might be more intuitive to have the blocking be similar to beams and openings, where you can really customize the location and size etc... of each row of blocks independently.
I usually have a pretty good idea how I want things to go even before I start coding but sometimes you get halfway into it and you realize that an alternative method or system would be more optimal.
How is the floor plug in coming along? I like what I see so far. Are we ready for BETA or are we kicking the can down the road again?
Nathan, Cant wait to see how the flooring plugin integrates with the other plugins with BIM package.
Hopefully, You'll have all the script finished soon.
Thanks
Wayne
Starting to work on it today, its been a while.
I see February 1st has come and gone. Are we getting any closer to having a floor plug-in? Can you update us on progress and issues that are holding up the project?
Thanks,
JK
The progress has been slowed by some ongoing health issues I've personally encountered however progress is being made and I am carefully coalescing on a new plugin which will replace the existing module in the Truss plugin. Also as updates have been made with various licensing updates within the other plugins I have been migrating those updates into this new plugin. I apologize in the significant delay with this new plugin but please remember that I am still a one man show and I am spread very thin across the development of six different plugins now. Each plugin requires a certain amount of attention as bug fixes, updates and feature requests all consume time and energy.
I realize that people are chomping at the bit for this new plugin and I have been working on it diligently for the last two to three weeks. The biggest holdup has been going back through all of the code and bringing it up to speed with the other plugins. There have been quite a few incremental changes to the other plugins with regards to licensing, materials, layers etc...
For instance the plugin material library back end was originally coded based off of the 2022 version of the Wall plugin. I just updated all of the code now so that it is keeping in line with the most current version of the Wall plugins material library code base.
(https://global.discourse-cdn.com/sketchup/optimized/3X/f/b/fba8e6d9e492d1eaed1437acff0e89a5031a4203_2_690x460.jpeg)
So right now I'm spending a few more days making sure everything is modern and up to speed with the other plugins.
I might actually designate the initial release a BETA number but I'm still not decided on that yet.
Right now the plugin is all torn apart as I continue to add in a few additional features like presets and the "remove joist list" option:
(https://global.discourse-cdn.com/sketchup/optimized/3X/b/c/bc5e1d5a179e2285bf2b54a7eb46d3cb01c4cf1d_2_666x500.jpeg)
This is my current desk setup, I've just added the big monitor to my left which gives me more screen real estate and improves my coding efficiency. This is where all the magic happens, at least for now.
I also initially used the slab-on-grade code for moving edges of the floor perimeter but now that I'm testing it more extensively it appears that I should probably switch to the code I use for the complex roofs, so some additional adjustments required there as well.
This is how the sausage is made, one line of code at a time.
The draw and edit menus are working great (all HTML) but I've decided I might as well add in "floor" presets since I know that request will be coming down pike if I don't add it in initially.
Also after using the current menus and given all the I-joist options (sizes and manufacturers) it seems almost cryptic in many ways unless you are intimately familiar with the various manufacturer's product numbers. I'm not saying now but maybe at a later date (after the initial release) I will add in a small SVG graphic into both of these menus which give a simple preview (cross section) with dimensions of the selected I-joist product. It would certainly make the menus a bit more graphic and exciting and actually be minimal work to implement, thoughts?
Just like you can do roof connections in the Truss plugin I am also enabling this feature within the Floor plugin as well as custom subtractions (SUBTRACT and CUSTOM).
I've been pushing the plugin all afternoon trying to find ways to break it and a few things eventually did jump out at me. One of which is the rim board algorithm and the sill plate algorithm (essentially the same algorithm but utilized differently). Other than that the basic joist (framing) algorithm seems very robust at this point no matter what strange configurations I try to attack it with:
(https://global.discourse-cdn.com/sketchup/optimized/3X/0/3/0325c31d9ec529e358395d97c8d7916767d52ae2_2_690x425.jpeg)
My initial framing method for the rim joists was to simply bevel/miter the joints, which makes sense if things are non-orthogonal but in practice when things are orthogonal the joints are usually lapped, at least that is what I've always seen in the field. If they are lapped then the question becomes do you lap the long or short parallel to the joists themselves. What I've always seen is the long rim joists are perpendicular to the joists however the user may want some control over this, so it is probably best to make this user definable (yet another option).
I will put my thinking cap on and start a new day tomorrow...
I think what I will do is provide three options for the joint treatment of both sill plates and rimjoists:
1.) Lap
2.) Reverse Lap
3.) Miter
Option #1 will be the default. When reverse lap is instantiated the long sided boards will run parallel with the joists. Most floors will be orthogonal and contain an even number of sides, so that makes things fairly straight forward. However, there is the possibility for odd sided floors (ie. 3, 5, 7, etc...), in such a case you will usually end up with a non-orthogonal corner somewhere along the perimeter of the floor. Even if option 1 or 2 is selected, if there are non-orthogonal corners I will simply miter those (for now). In the future I may add an additional global setting which also allows for lapped non-orthogonal corners, but right now I don't want to spend too much time in the weeds on this.
Thoughts?
Here is an example of the three options for handling joints of both sill plates and rimjoists. Note that they are independent of each other:
(https://global.discourse-cdn.com/sketchup/optimized/3X/2/a/2a4e8c6f99dced27820edc005d001f37909233d3_2_690x421.jpeg)
How soon should I release the BETA version? I'm currently checking the floor preset functionality and I will also look at the addition of insulation (bat or fill) tomorrow. The gypsum (ceiling) seems to be working great, but eventually I will add in battens because I know someone will request it, but it is not top priority right now.
I'm thinking I will push out the opening and beam modules after I release the BETA, they will complicate things and may take a few weeks of tweaking and testing before they are ready for prime time. The opening module will be the higher priority of the two.
I've created the template for the integration with the estimating module, but this will also require further fleshing out. In addition there will need to be updates to the cost database and weight database modules that integrate materials for the floor assemblies.
I'm honestly not sure how useful the connection function is as compared to the Truss plugin, but it will be a feature since most of the heavy lifting is already done.
The CUSTOM and SUBTRACT feature will be similar to the Truss plugin, it is in place and appears to be working as it should, further testing would be prudent.
The I-Joist libraries (sizes and types) is much more organized than the previous system and should be easier to maintain and if required more manufacturers can be easily added. I may also add in a "custom I-Joist" option which would allow one to specify the full set of dimensions for a custom sized I-Joist (depth, flange depth, flange width, web width, web material etc...)
Similar to the Truss and Wall plugins, one can specify a comma deliminated remove list to remove specific joists from an assembly.
Still lots to do but it is almost close enough to the finish line to think about putting it out there and start garnering feedback and suggestions.

Added a "Floors" tab to the global settings, I'm sure this tab will get more populated as development progresses.
(https://global.discourse-cdn.com/sketchup/optimized/3X/5/3/531ad3aa880015b2cbaed680e04249ffe0a63abe_2_522x500.jpeg)
The tool tip in the draw and edit menu.
Batt and Blown insulation are now enabled:

In the Materials tab of the Global Settings you can switch between the more realistic textures/materials for lumber and pressure treated lumber:
(https://global.discourse-cdn.com/sketchup/optimized/3X/0/e/0e9266b1e402e138fa7e809ac73d563fe6f459db_2_690x436.jpeg)

I've updated the algorithm for non-orthogonal cut lumber so that even angled cuts will now show an end grain texture:
Goldplating for sure, but I think the proper material helps visualize better what is actually going on within the construction project.
(https://global.discourse-cdn.com/sketchup/optimized/3X/a/3/a3cbdc1cca99a8e4d35c65e997bb17e8a1935212_2_690x426.jpeg)
First look at a mitered rim joist:
(https://global.discourse-cdn.com/sketchup/optimized/3X/c/c/cc04e923117b4f64787fa7ca3aae68d2b2ba4b62_2_690x348.jpeg)

I know, no one builds it this way but I'm just covering all my bases.
I just need to test the sill plate algorithm tomorrow morning and I think we are ready for an initial BETA release.
Nathan,
Good Morning, The floor extension looks great, cant wait to add it to the suite.
Thank You,
Wayne
First look at a mitered sill plate (pressure treated).
Notice that I don't have an end grain for LSL or PSL materials yet, not a huge deal but something to add to the todo list when things slow down a bit.
(https://global.discourse-cdn.com/sketchup/optimized/3X/4/9/49614b94301f4eeb831e549aaaf5614921976065_2_690x402.jpeg)

A reverse lapped rim joist with a regular lap on the sill plate:

I think I will forego the "solid" option for the rim and sill for now. If requested I will add it in but I don't consider it a priority right now.
The Move Floor Edge tool is working as it should:
(https://global.discourse-cdn.com/sketchup/original/3X/2/f/2f898ba0aacfc575f4d93149558c2946560b2eac.gif)
Version 0.9.0 - 09.08.2024
- Created the Medeek Floor Plugin, utilizing SketchUp's Ruby API.
- Added the draw floor tool with the ability to create I-Joist and solid sawn (lumber) polygon shaped floors.
The Floor extension can be downloaded directly here:
http://design.medeek.com/calculator/sketchup/medeek_floor_ext.rbz
Note that this is a BETA release and does not include all of the future planned functionality (ie. openings, beams etc...) I am only posting this release in a few select locations to allow power users to test it out first and help me further debug and refine it. After approximately a week I will send out a notification to all users letting them know that the release is now publicly available. Hopefully in that time I can catch the most glaring bugs and issues so that my inbox does not become swamped.
Also all those who have been issued licenses in the last year or so will have their expiration update date of their license automatically renewed so that it will be active for one year starting from tomorrow's date (09/09/2025).
I desperately need to work on the hole tool and the floor covering tool. These two additions will make the plugin truly powerful. At this point it is not much better than the previous floor module in the Truss plugin (other than the ability to create polygon floor outlines).
There will be instances that hangers will be utilized however joists that are cut at diagonals will complicate the matter somewhat, I'm not even sure what hardware is available in that regard, I will have to spend some time researching that one and then coming up with a clever algorithm.
Please email me any feedback directly to nathan@medeek.com, any and all feedback is appreciated.
I've already updated the database so anyone who holds a license for the plugin has now had their license renewed for a full year.
The current todo list in no specific order:
1.) Floor Coverings: Tile, Carpet, Hardwood etc...
2.) Floor Openings: Stairwell and Crawlspace or ladder access
3.) In Floor Beams
4.) Blocking: Mid-span blocking, custom blocking, edge blocking
5.) Ledgers: customize each edge or side of an assembly with a custom ledger or rim joist setting.
6.) Hardware: Joist Hangers, Beam Hangers, diagonal bracing, deck holdowns
(https://global.discourse-cdn.com/sketchup/original/3X/8/8/8813685c5da5b61a8df9ee0877f25cd24f7a9297.jpeg)
7.) Railing: for decks
8.) Custom Joist Doubling: ability to double any number of joists in the array

(https://global.discourse-cdn.com/sketchup/original/3X/3/7/37bd5b16324224ae145a6f8ea492eeb36314d53a.jpeg)
Version 0.9.3 - 09.12.2024
- Fixed a critical bug in the Draw Floor menu.
- Added a status icon (Draw Mode: Polyline or Face) in upper right corner of the Draw Floor menu.
- Added the Draw Mode parameter to Floors tab of the Global Settings.
I was thinking about hanger hardware for the joists but then I realized that things are quite a bit more complicated with these polygon floors. For example look at this floor:
(https://global.discourse-cdn.com/sketchup/optimized/3X/0/4/04f9f24def081583ba8d8fd4900ee2fa669d9387_2_690x427.jpeg)
The situation gets interesting for the first six joists in the array, they would require four hangers each rather than just the normal two. I'm going to have to really put on my thinking cap for this one.
And then you have the additional complication of non-orthogonal edges which may require special skewed hangers... Fortunately those are probably not as common so I can probably ignore that case for now.
P.S.
I may have to bounce some ideas off of @DanRathbun and the other great minds on this forum to devise an efficient algorithm.
At first glance I think I can examine each joist individually once they've been trimmed/cut and count the number of edges that run parallel to the joist (x-axis or y-axis). For a regular lumber joist the total number of pieces will be the number of horizontal (long edges) divided by four. That will tell me how many hangers I actually need.
I can then cycle through this collection of edges finding all of the terminal vertices/locations and assign to each one a direction (left facing or right facing). From there it is simply a matter of running a for loop and placing the hangers. I think this will work but it may not be optimized yet.
P.P.S
I also just realized that there is the possibility for some joists to be doubled, which will naturally require a different hanger, so the hanger selection will require two parameters, one for single ply an one for two ply. However, there may be a situation where you want there to be hangers only on one side of the floor (ie. a deck with a ledger and beam supported on the other end) so four parameters for hanger selection:
1.) Start Hanger (1X Ply)
2.) Start Hanger (2X Ply)
3.) End Hanger (1X Ply)
4.) End Hanger (2X Ply)
Version 0.9.3b - 09.12.2024
- Fixed a HTML/Javascript bug in the Draw Floor menu.
Not sure why anyone in their right mind would create a floor like this but it seems like the hanger algorithm is holding up even when I throw the kitchen sink at it. I will have to test a few more things and then I'll probably release the joist hanger update tomorrow.
(https://global.discourse-cdn.com/sketchup/optimized/3X/e/e/eee6512540fe9c042e050cdef914f77c872459d8_2_690x471.jpeg)

It would be nice is one could specify every terminal end of joist (ie. hanger or no hanger and even specify a size). However I'm probably not going to go that granular yet.
Version 0.9.4 - 09.16.2024
- Added joist hangers to the Draw and Edit menus.
- Added a built-in library of face mount and and top flange hangers.

- Added a "debug mode" parameter to the General tab of the Global Settings.
- Fixed a bug with deck board placement.
- Fixed a bug with the deck board offset parameter.

I have had two requests now for metal bridging or bracing so I took about an hour and modeled up a Simpson TB27 between 2X10 joists @ 16" on center. It actually looks really nice:
(https://global.discourse-cdn.com/sketchup/optimized/3X/3/4/340ab6f90ac81b266818e3b0f4f64b7ade3b68ef_2_690x423.jpeg)
(https://global.discourse-cdn.com/sketchup/original/3X/4/0/40b036ce61c8b8fc1863d73a019d386452d4423b.jpeg)
However some things immediately jumped out at me:
1.) I based my TB27 off of the ICF file on Simpson's website so it is dimensionally accurate, however to do that takes quite a bit of time. Modeling like this is fun but very time consuming and one thing I never have enough of is time.
2.) This is the TB27 configured for 2X10's on 16" centers, now think of all the other permutations (including I-Joists). To make this look right would require a preconfigured component for each case. The number of permutations is at least 130 or more.
(https://global.discourse-cdn.com/sketchup/original/3X/4/d/4da8cb6fb26424d77a8c54827b2ca1bf9bbf75aa.jpeg)
3.) If you also consider custom offsets of specific joists then it gets even more crazy.
My thinking is that if I do want to enable something like this it will need to be less detailed geometrically (just a basic representation) and drawn on the fly using an algorithm that checks joist depth and spacing. Rather than specify the exact part number (ie. TB20, TB27, TB30 etc...), just specify that it is metal bridging.
Version 0.9.6 - 09.19.2024
- Fixed a bug with metric floor presets.
- Fixed a bug with the insulation module.
I am changing up the way in which I do subtractive geometry from the way I've done it with the other plugins in the past.
If you enable Subtractive Geometry in the global settings you can use the SUBTRACT keyword to cut holes through everything as per normal. However you will now also have two other options:
SUBTRACT_SHEATH: This keyword will only subtract through sheathing, flooring and deck boards.
SUBTRACT_GYPSUM: This keyword will only subtract through gypsum
I may add others as the need arises or additional requests are made.
P.S.
SUBTRACT_FRAME: This keyword will only subtract joists, rim joists and insulation. I will probably extend this keyword to include in-floor beams once that feature is added.
This brings the number of subtraction geometry options to four.

I think this method is far superior to the system I employed in the Truss plugin and eventually I will update all the plugins with a similar system which will allow more granular control over these types of boolean subtractions within assemblies.
