LegoFace adds a "Transform to LEGO face" entry to the Part Design Face Tools task panel (shown when a planar face is selected). It generates LEGO-compatible studs (male) or sockets (female) on the face as native Part Design features (a Sketch attached to the face + Pad/Pocket), so documents stay fully editable and open without the addon installed.

Features: auto-computed adjustable N×M grid at the 8 mm LEGO pitch, layouts (full face / spread with 3 densities / border / sides), and an "FDM printing" checkbox adding clearance on the female side. English UI with a French translation following FreeCAD's language preference.

Technical points for the review:

• Modern namespaced layout (freecad/LegoFace/), no sys.path manipulation, no Python dependencies, FreeCAD ≥ 1.0 (tested on 1.1.3). Manifest declares the <other> content type since the addon provides no workbench.
• Transparency on one point: the addon's purpose is to extend the Part Design Face Tools task panel. Since Gui.Control.addTaskWatcher() replaces the whole watcher list, the addon replicates the stock Part Design watcher list (from PartDesignGui::Workbench::activated()) with its single command inserted, and reinstalls it when the Part Design workbench is activated. The stock panel is preserved identically; the code is isolated in one module (watcher.py) and wrapped in try/except so any failure leaves the standard panel untouched. I'm happy to adapt this approach if the team prefers another integration point.
• Headless test suite included (FreeCADCmd tests/headless_test.py).

Release: v0.2.0 (tagged). Repository topics freecad and addon are set. Thanks for reviewing!

Nice idea! I really only have one change to request before Indexing... the brick corporation in question is infamously litigious, and this particular addon falls directly afoul of their "Fair Play" guidelines. This is not to say it's actually in violation of any law (trademark or otherwise), only that this company will surely assert that it is, and is known to do so on a quite wide-ranging basis. I am not myself a lawyer, nor are any of the others who I could call upon to review this submission. Therefore... I ask that before we add your addon to the Index, you rename it so that it does not use that particular corporation's name in its name, or in any command name that might then end up displayed in a screenshot of a FreeCAD menu. Note that the Addon Manager's "search" function will happily search the "description" field of the addon's manifest file, so this will not harm your addon's discoverability.
