MeasureTool

A measuring tool for Unreal Engine. Drop a measure actor into your level, pick two anchor points, and get a live, camera-facing distance readout drawn directly in the viewport — complete with a ruler-style line, tick marks, and a units label.

Features

• Two-anchor measurement — measure the distance between any two actors in the level.
• Live editor preview — the line and label update every frame in the viewport, including when you drag the anchors around. No PIE / runtime needed.
• Camera-facing ruler line — a billboarded procedural-mesh line keeps a constant apparent thickness from any viewing angle, with optional tick marks spaced at one display unit each.
• Unit conversion — display in centimeters, meters, kilometers, inches, feet, yards, or miles.
• Configurable label — toggle visibility, set decimal precision, slide its position along the line, and choose its color.
• One-click anchor creation — spawn anchor TargetPoints straight from the details panel.
• Pivot snapping — re-center the actor's pivot on anchor A without moving the anchors in world space.

Usage

1. In the Content Browser, navigate to MeasureTool Content and drag BP_MeasureActor into your level.
2. Assign the two endpoints you want to measure:
   • Set Anchor A and Anchor B in the details panel to any actors already in the level, or
   • Click Create Anchor in the details panel to spawn a TargetPoint at the measure actor's location. The first click fills Anchor A, the second fills Anchor B. New anchors are attached to the measure actor and named <Actor>_AnchorA / <Actor>_AnchorB.
3. Move the anchors. The line, tick marks, and label update live, and the read-only Distance CM field reflects the raw distance in centimeters.

Tip: BP_MeasureActor is the intended entry point. The underlying C++ class AMeasureActor is marked Abstract and cannot be placed directly.

Properties
