# Session Walkthrough - Measurement Tools & Refactoring

## accomplished Goals
This session focused on fixing critical bugs in the new measurement tool and improving the user experience of the preview window.

### 1. Bug Fixes
*   **Import Error**: Resolved `ModuleNotFoundError: No module named 'sec_interp.gui.tools'` by adding the `gui/tools` directory to `scripts/deploy.sh`.
*   **RubberBand Error**: Fixed `TypeError` in `QgsRubberBand` constructor by updating it to use `QgsWkbTypes.LineGeometry` for compatibility with QGIS 3.x.

### 2. Feature Implementation
*   **Dynamic UI**: Implemented logic to enable/disable "Show Topography", "Show Geology", and "Show Structure" checkboxes based on data availability.
    *   Added `is_complete()` methods to `DemPage`, `GeologyPage`, `StructurePage`, and `SectionPage`.
    *   Connected signals in `MainDialog` to update checkbox states dynamically.
*   **Measurement Tool**: Successfully integrated and deployed the interactive profile measurement tool.

### 3. Documentation & Process
*   **Technical Report**: Generated a detailed report of refactorings (`docs/technical_refactoring_report_2025-12-09.md`).
*   **Changelog**: Created a draft changelog for v1.1 (`docs/CHANGELOG_DRAFT_v1.1.md`).
*   **Standards**: Defined image naming conventions (`docs/DOCUMENTATION_STANDARDS.md`).
*   **Git**: Merged `feature/measurement-tools` into `main` and pushed changes.

## Verification Results
*   **Deployment**: Validated that `scripts/deploy.sh` correctly copies all plugin files.
*   **Functionality**: Confirmed that the measurement tool works and that checkboxes respond correctly to user input.

## Next Steps
*   Create visual assets for the documentation following the new standards.
*   Begin research/implementation on detailed drill logs (`drilllogs_research.md`).
