Antigravity FreeCAD Integration Progress

Overview

This session focused on expanding the programmatic control of FreeCAD via the Antigravity bridge, creating parametric object generators, and researching deeper integration methods.

New Scripts

We developed Python scripts to generate specific geometry programmatically.

2x6 Lumber

• **Script:** `create_2x6.py`
• **Function:** Generates a standard 2"x6"x8' lumber piece.
• **Method:** Uses `FreeCADTemplates` to create a box with correct dimensions.

Screwdriver

• **Script:** `create_screwdriver.py`
• **Function:** Generates a multi-part screwdriver model.
• **Components:** Red handle (grip, collar, cap), silver shaft, dark grey flathead tip.

Worm Gear

• **Script:** `create_worm_gear.py`
• **Function:** Generates a worm screw.
• **Method:** Uses `Part.makeHelix` and `Part.Wire.makePipeShell` to sweep a trapezoidal profile along a helical path.
• **Output:** Saved to `outputs/WormGear.FCStd`.

Induction Furnace

• **Script:** `create_induction_furnace.py`
• **Function:** Generates a parametric model of an Induction Furnace based on OSE specifications.
• **Components:** Refractory crucible (hollow cylinder) and copper induction coil (helical tube).
• **Output:** Saved to `outputs/InductionFurnace.FCStd`.

Integration Enhancements

Research

Identified three key areas for deeper integration:

1. **Reactive Event Listening:** Using `DocumentObserver` to detect user actions.
2. **Embedded UI:** Custom `TaskPanel` for in-app chat and control.
3. **Bi-Directional Sockets:** Asynchronous communication for real-time feedback.

Demo

• **Selection Observer:** Modified `antigravity_freecad.FCMacro` to include a `SelectionObserver`.
• **Result:** FreeCAD now reports selected objects to the listener log, demonstrating the ability of the system to "see" user focus.
