SolidCraft 0.26.1 all-in-one

SolidCraft 0.26.1 all-in-one (2026-10-29): everything we have, on upstream 0.26.1 (Windows x64)

Not for engineering use. The simulation features (Airflow studies, the fan and compressor
tools) are experimental. Use them to compare designs, not for absolute numbers. Accuracy so far:
https://github.com/dudedagger42/solidcraft/blob/main/docs/airflow-validation.md

Unzip anywhere and run solidcraft.exe. solidcraft-cli.exe is the command-line tool. SolidCraft for Claude.bat opens it with its control port on 7878, so Claude can work in the window; SolidCraft.mcpb is the Claude connector.

Upstream main of 2026-10-29 (version 0.26.1), plus everything in the 0.25.1 all-in-one, and:

• Liquid Craft themes: Preferences (Ctrl+,) → Interface → Theme → Liquid Craft or Liquid Craft Dark. Glass panels over the model; text turns dark or light to stay readable against what is behind it. Four sliders under the theme set the look: Glass blur, See-through, Edge bend and Edge reach.
• Sketch fixes: the same constraint twice between the same entities adds nothing; an arc's radius text sits in the middle of the arc; Offset chains lines whose corners only coincide; a constraint the sketch already implies is refused, and the status bar says why.
• Picking: edges seen through a see-through body, or drawn hidden, can be clicked; a dialog input that takes bodies lights the whole hovered body; dragging geometry keeps following the pointer over a floating card.
• Extrude: a Cut To the far side of a curved wall takes the wall (tangency-labs#8634).
• View cube Set as Front / Top (tangency-labs#6493), rebased onto 0.26.

Known issues in this build:

• The simulation workspace is as in 0.25.1: there, but not ready to use. Its strings are not translated into Arabic, Hebrew or Vietnamese.
• 16 of about 6,950 tests fail. 7 failed in 0.25.1 too and 2 more are the simulation panel. The other 7: four tests on the Interface preferences page, which the glass sliders made longer; two text mismatches (an untranslated "Center", "modeling" spelled "modelling"); and a GPU draw count. The GPU path-tracing tests were not run.
• Not every feature was tried by hand in the window; if something looks wrong, check fixed-and-added.md, then tell me.

Install or update

• New install: download solidcraft-0.26.1-all.zip, unzip anywhere, run solidcraft.exe.
• From the 0.25.1 all-in-one: Preferences → General → Updates → Check now (or the Update button in the title bar), or unzip this over the old one.

solidcraft-windows-x64-portable.zip is the same file under the name the in-app updater looks for; SHA256SUMS.txt lets it verify the download.

SolidCraft 0.25.1 all-in-one

SolidCraft 0.25.1 all-in-one (2026-10-28): everything we have, on the 0.25.1 release (Windows x64)

Not for engineering use. The simulation features (Airflow studies, the fan and compressor
tools) are experimental. Use them to compare designs, not for absolute numbers. Accuracy so far:
https://github.com/dudedagger42/solidcraft/blob/main/docs/airflow-validation.md

Unzip anywhere and run solidcraft.exe. solidcraft-cli.exe is the command-line tool. SolidCraft for Claude.bat opens it with its control port on 7878, so Claude can work in the window; SolidCraft.mcpb is the Claude connector.

Upstream v0.25.1, plus upstream PR tangency-labs#7959 (all toasts in one stack), plus everything in the 0.24 all-in-one, and:

• Solid Glass theme: Preferences (Ctrl+,) → Interface → Theme. Pick an Accent colour there and the selection, the logo and the Model tool icons all follow it.
• Parts library: the panel sizes itself to fit its thumbnails (no dragging, no title), part thumbnails have see-through backgrounds, and the History bar sits beside the panel instead of under it.
• Title bar: a long version number no longer runs into "Report a bug".
• Sketch and Model keys kept apart (tangency-labs#7675): a sketch shortcut no longer fires a Model command, and the other way round.
• 3D-sketch moves along Z (tangency-labs#7665), a second thread series (tangency-labs#5128), and a fix so pressing V no longer hides the sketch you picked (tangency-labs#5167).
• All our open pull requests are rebased onto upstream 0.25.1 and included, as in 0.24: view cube Set as Front / Top, Sketch Break, the value box, canvas face pick, projection rebuilds, plane resize, extrude to a corner, thread clearance, chamfer over a joined pin, and the sketch/viewport fixes.

Updated 2026-10-28 (build 686fbfb): same version, files replaced. The value box holds still under the pointer only when the wheel steps values; the Parts library panel uses the shared panel frame and right-click menu (a thin border like the other panels); a spelling clash in the toast position option fixed. If you downloaded it before, download it again or unzip this over it.

Known issues in this build:

• 8 of 3021 UI tests fail in the build (each of our pull requests passes them on its own): the Airflow strings are not translated yet, the Airflow toolbar command, and a few places where two merged changes meet (hole preferences, pattern and sketch previews, length defaults, two sketch corner tests). The GPU rendering tests were not run.
• Not every feature was tried by hand in the window after the 0.25.1 merge; if something looks wrong, check fixed-and-added.md, then tell me.

SolidCraft 0.24.0 all-in-one (b816495c)

SolidCraft 0.24.0 all-in-one (2026-10-27): everything we have, on the 0.24.0 release (Windows x64)

Not for engineering use. The simulation features (Airflow studies, the fan and compressor
tools) are experimental. Use them to compare designs, not for absolute numbers. Accuracy so far:

Unzip anywhere and run solidcraft.exe. solidcraft-cli.exe is the command-line tool. SolidCraft for Claude.bat opens it with its control port on 7878, so Claude can work in the window; SolidCraft.mcpb is the Claude connector.

Upstream v0.24.0, plus upstream main since the release (28 commits), plus everything in the 0.22 all-in-one, and:

• Round axes now come from upstream (tangency-labs#4610): Revolve, Circular Pattern, Plane at Angle and Move take a round face or edge as an axis that follows the model when it changes. This replaces our own version.
• Thread clearance for printed threads: Wider or Narrower fits (upstream issues tangency-labs#4087, tangency-labs#4153; PR tangency-labs#7142).
• Thread sizes: the custom-size problem listed in 0.22's known issues is fixed.
• Our open pull requests are rebased onto upstream main and included: 3D-sketch moves, view cube Set as Front / Top, Sketch Break, the value box, canvas face pick, projection rebuilds, center of mass, plane resize, extrude to a corner, sketch/viewport fixes, chamfer over a joined pin.

Known issues in this build:

• Three of our tests fail that also fail on plain upstream code (two thread-dialog contribution tests and one spline-on-revolve test); nothing new.
• Not every feature was tried by hand in the window after the 0.24 merge; if something looks wrong, check fixed-and-added.md, then tell me.

SolidCraft 0.22.0 all-in-one (f19a3fec)

SolidCraft 0.22.0 all-in-one (2026-10-25): everything we have, on the 0.22.0 release (Windows x64)

Not for engineering use. The simulation features (Airflow studies, the fan and compressor
tools) are experimental. Use them to compare designs, not for absolute numbers. Accuracy so far:
https://github.com/dudedagger42/solidcraft/blob/main/docs/airflow-validation.md

Unzip anywhere and run solidcraft.exe. solidcraft-cli.exe is the command-line tool. SolidCraft for Claude.bat opens it with its control port on 7878, so Claude can work in the window; SolidCraft.mcpb is the Claude connector.

Upstream v0.22.0 plus everything in the 0.21 all-in-one (see fixed-and-added.md), and:

• Airflow runs on the GPU in every tab. In 0.21, a design opened in a new tab fell back to the CPU solver (slow, capped at 2 million cells).
• Airflow accuracy fixes: inlets deliver the flow you set (they were up to 32 % low), fans and other driven flows push as hard as they should, and long GPU runs no longer trip the Windows driver watchdog. Laminar duct flow is validated to about 1–2 %; turbulent flow is still not reliable (pressure drops read high).
• Updates from: Preferences → General → Updates now chooses where updates come from: this Airflow build (the default) or official SolidCraft. Choosing official installs the official app in place of this one, without the Simulation tab; switch back to get this build again.
• View cube: Set as Front / Top. Right-click the view cube to make the face you're looking at the design's FRONT or TOP. The standard views, Home and the orbit follow it, it's saved with the design, and Reset Orientation undoes it (upstream issue tangency-labs#6455, PR tangency-labs#6493).
• Ctrl+Z undoes showing and hiding bodies (upstream tangency-labs#4780, merged after 0.22.0).

Known issues in this build:

• Custom sizes and pitches in the Thread dialog fail five of our tests after the 0.22 merge: check a custom thread before relying on it.
• Clicking a body's corner while extruding by a distance no longer switches to "To Object" at that corner; pick To Object first.

If something looks wrong, check fixed-and-added.md first: if it's listed as fixed, tell me; if not, we check whether plain 0.22 does it too.

Install or update

• New install: download solidcraft-0.22.0-all.zip, unzip anywhere, run solidcraft.exe.
• From the 0.21 all-in-one: 0.21 checks official SolidCraft for updates, so it will offer official 0.22.0, which replaces this build and removes Airflow. Instead, download this zip and unzip it over (or beside) the old one. From 0.22 on, updates come from this page by default (Preferences → General → Updates from).

• Ctrl+Z undoes showing and hiding bodies (upstream tangency-labs#4780, merged after 0.22.0).
• Sketch Break no longer skews a dimensioned line or stacks zero-length pieces and constraints when clicked again at the same spot (upstream issue tangency-labs#6826, PR tangency-labs#6834).
• The value box (Radius, Distance…) sits just outside the model's outline, level with its handle, instead of on the edge you're editing (upstream issue tangency-labs#6827, PR tangency-labs#6836).
• Parts library: a Normal size (now the default), and Small, Normal and XL are really different sizes (Columns is the most per row).

Known issues in this build:

• Custom sizes and pitches in the Thread dialog fail five of our tests after the 0.22 merge: check a custom thread before relying on it.
