agreed - i'd say less detail on the components to improve speed and rendering, and just good descriptive text / names instead. one option might be in a "library" view showing a detailed version of a single component so selection purposes, but the generated structure uses the simpliest possible geometry.

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.

Adding in the advanced floor options into the Global Settings:

I am working on adding in metal bridging with some associated parameters:

P.S.
I was going to combine the metal bridging with the solid blocking however after some thought I realized there might be cases where you might combine both forms of bracing in one floor (solid blocking and metal bridging). Hence I need a separate module for blocking. Unlike the wall blocking floor blocking may be regular lumber or I-Joist blocking so that further complicates the matter slightly.

The parameters for the blocking module will probably be:

1.) Blocking Type: Lumber/I-Joist

If blocking type is Lumber:

Blocking Width: 1.5 in (default)

Blocking Material: Lumber / PT Lumber / LSL / PSL / LVL etc...

If blocking type is I-Joist

Blocking I-Joist Family:

Blocking I-Joist Type:

other general parameters are:

Row Spacing: 96 in. (default)

Stagger Blocking: Yes/No

Remove Row: empty by default

Quite a few more parameters (8) to add into a number of files, this will keep me busy for a couple of days at least.

First look at metal bridging (I-joist and Lumber):

Geometrically a lot simpler and more lightweight than the preconfigured component that I made based off of the Simpson IFC model. I'm using my galvanized texture/material but I may change it slightly. There are quite a few parameters that one can adjust to customize the look and feel of these metal bridging straps, hopefully that should make things configurable enough for most power users.

As noted per the Simpson literature the crossing straps should not be in direct contact to avoid screeching noises when they move under load. Hence the default 1/8" gap, but this can be modified as can be seen in the menu.

I've also included a thickness parameter for the straps. The correct thickness for a 20 gauge strap is probably around 0.035" however I've rounded the default value to an even 0.04".

Version 0.9.8 - 09.27.2024

Made the polyline/face icon (draw mode) in the draw menu clickable.
Added a joist direction toggle button/icon to the draw and edit menus.
Added a stagger joist option to the Draw and Edit menus.
Updated the insulation, blocking, metal bridging and hanger modules to accommodate staggered joists.

medeek

So yes, staggered joist present a few issues. For example if the blocking doesn't land in the lapped region of the joist layout you end up with this:

Right at the moment I'm not sure how to address this or actually determine when the blocking lands in the non-lapped sections of the layout. The easy way out would be to do a boolean subtraction using the joists themselves, but then I would need to separate the resulting (multi-body) group into a bunch of groups/solids, this one is a bit of headache.

medeek

With staggered joists I am tracking how many rows of joists I need, the joist length and lapped length, so given that information (three variables) I can then run a quick check on each blocking row to see how it pencils out. This little block of code does the trick:

if @Spanno < 2
			stoffset = 'NEG'
		else
			lapcount = 1
			for lapi in @Stjarray
				if (distx > lapi[0]) && (distx < lapi[1])
					stoffset = 'LAP'
					break
				elsif distx < lapi[0]
					if lapcount.odd?
						stoffset = 'NEG'
					else
						stoffset = 'POS'
					end
					break
				elsif (distx > lapi[1]) && (lapcount == (@Spanno - 1))
					if lapcount.odd?
						stoffset = 'POS'
					else
						stoffset = 'NEG'
					end
					break
				end

				lapcount = lapcount + 1
			end
				
		end

As one can see there are really only three possibilities for the blocking: Lapped, Positive or Negative.

The end result is this:

Problem solved. Now I just need to apply this same logic to the metal bracing and implement it. Insulation is somewhat different so I still don’t have a good solution for that one just yet.

medeek

After another three hours of some productive thought and hacking away at some rather large blocks of code (and a few choice words) I managed to pull together a fairly efficient and robust algorithm for the cavity insulation between those irregular joists.

Ladies and Gentlemen, I give you “Batt Insulation with Staggered Joists”:

I’m exhausted, tomorrow I might take a small break.

gullfo

what if i want them staggered the other way? LOL J.K. nicely done!

medeek

First look at skewed hangers with staggered joists:

A little bit more complicated than regular joists due to the offsets but overall its pretty much the same routine. Pretty excited that I actually can get this to work, at first I wasn't really sure if it was even feasible.

A quick test of the non-orthogonal floor types shows that the algorithm holds up as it should:
