This helps maintain optimal mesh density and visual quality based on configurable rules. **Key Features:** * **Live Measurement:** Displays the distance between two selected vertices or the maximum span of selected edges or polygons. * **Segment Recommendations:** Suggests minimum and "good" segment counts based on the measured diameter. * **Configurable Units:** Supports Millimeters (mm), Centimeters (cm), Meters (m), and Inches (in) for display. * **Customizable Rules:** Define your own diameter thresholds and corresponding segment recommendations. * **Presets:** Save, load, import, and export your recommendation rule sets. * **Customizable Overlay:** Control the appearance of the 2D text and 3D measurement line (colors, size, position). * **QA Mode:** A special display mode to compare the current segment count of selected edges against the recommended range. * **Performance Controls:** Adjust update frequency and calculation limits to balance responsiveness and CPU load. The addon is accessible via the 3D View Sidebar (N-Panel) under the "NOVA ARC" tab and through Addon Preferences.
