DGOneGizmo User Guide (UE5.5 ~ UE5.7, v1.1.19)

1. Plugin Overview

DGOneGizmo is a dimension measurement and visualization plugin for Unreal Engine 5. It supports:

• Displaying real object dimensions (X/Y/Z) in the viewport.
• Drawing visual bounding boxes for selected objects.
• Two-point distance measurement in 3D view (persistent workflow, preview state, eraser, and clear-all).
• Skeletal mesh measurement with viewport-depth-first picking and vertex snap (imported/skinned hybrid).
• Distance/axis rendering with distance-adaptive thickness and soft overlay style.
• Label panel border + corner leader lines mapped to the corresponding bounding box color.
• Global preference configuration (units, display, precision, refresh rate, trace channel, etc.).
• Both Editor and Runtime scenarios.

2. Feature Overview

2.1 Dimension Display (Bounds)

• Supports two dimension references:
  • World AABB: World-space axis-aligned bounding box, intuitively reflecting occupied volume in the scene.
  • Local Bounds: Original local size, unaffected by world rotation.
• Supports both single-object and multi-object (combined bounds) calculation.

2.2 Visual Bounding Box

• Draws boxes for visible collision/render components of selected objects.
