Professional Measurement Tool is an advanced, C++ native spline-based measurement plugin for Unreal Engine. It allows level designers and environment artists to measure distances and enclosed 3D polygon areas directly inside the editor with real-time visual feedback.
Unlike basic blueprint rulers, this tool features a Custom Editor Mode with a dedicated Slate toolkit panel, making it feel like a native Unreal Engine feature.
Key Features:
Distance & Area Modes: Measure linear paths or calculate the exact area of enclosed 3D polygons using Newell's method.
Custom Editor Mode: Access the tool directly from the Modes dropdown. Spawn, manage, and delete measurement actors via a clean UI panel.
Geometry Snapping: Advanced snapping system (Ground Trace & Nearest Surface) to perfectly align your splines to your level geometry.
Multiple Units: Instantly switch between Centimeters, Meters, Kilometers, Feet, Inches, and Yards.
Live Visual Feedback: Real-time, camera-facing billboard widgets, cumulative distance labels, and angle arc visualizations.
Developer Friendly: Fully decoupled architecture using Interfaces. Exposes BlueprintCallable functions for runtime calculations if needed.
Perfect for architectural visualization, level design blockouts, and technical projects.
