Small but meaningful update on the MUZWalls side: double (cavity) walls got a proper round of improvements this
release, and the Quantities takeoff has been taught to keep up with them. If you do any masonry or cavity-wall
detailing in SketchUp, this one's aimed squarely at you.

The short version:

• Shared leaves now stay in sync across the whole model
• Cavity fill (mortar / sand) is now a first-class layer
• Insulation gets its own layer (rigid board or batt)
• Both show up in Quantities, with window/door openings subtracted automatically
• New double walls default to 110 mm per leaf, matching the regular wall default

A bit more on each:

Shared leaves stay in sync
If two double walls share the same leaf type — say both use an inner leaf called "Brick-02" , editing one now updates
the others automatically. Change a thickness, swap a material, tweak a finish, and every double wall in the model
using that leaf rebuilds to match. It just happens: edit one, the rest follow. No new button, nothing to toggle.

Deleting a double wall now also cleans up its leaf groups properly, so you're not left with orphan geometry piling up
as you iterate.

Cavity fill
A new layer between the two leaves, for mortar fill, sand fill, or any solid infill you want shown in the model and
counted. You set it up in the Double Wall Settings dialog, and there's a new ready-to-use texture bundled in for it.

Insulation
A separate cavity layer, for when you want rigid board or batt insulation modelled distinctly from a structural fill.
Also configurable in Double Wall Settings.

The two are independent, enable one, both, or neither. With both on, the order runs outer leaf → cavity fill →
insulation → inner leaf.

They get counted, too
Quantities picks up two new report modes, one for cavity fill and one for insulation. Volumes account for openings on
their own, windows and doors are subtracted from the layer totals, so there's no fixing up the CSV/Excel export by
hand.

One default change
New double walls now start at 110 mm per leaf (was 100 mm) it matches the regular wall default and tends to be the
more common starting point for cavity detailing. Existing projects aren't touched; only newly drawn double walls use
the new starting value.

Updating
In SketchUp: Extensions → Extension Manager, uninstall the previous MUZWalls, then install the new .rbz from the
download page. Your license activation carries over, so there's nothing to re-activate.

Would love to hear how it lands for you, especially if you're detailing cavity walls day to day. I'll be around to
answer questions in the thread, and if anything misbehaves, tell me and I'll dig in.

Cheers,
