Measurement & Annotation Tool

Module: Design · Category: LevelDesign · Tool ID: MeasurementAnnotationTool

Measures distances between selected actors, bounding box dimensions of selected actors, and path distances along multi-actor selections. Displays results in centimeters, meters, or feet — copy to clipboard or clear results in one click.

Tool open with several measurements taken between selected actors, results list showing labels and values.

When to use it

• Verifying gameplay distances: “is this gap really jumpable?”
• Confirming character-scale geometry (door heights, corridor widths)
• Reporting measurements to designers / writers via clipboard
• Cross-referencing reference images (with Reference Image Overlay)

What it isn’t for

• Don’t use this for navigation analysis. See World-Scale & Traversal Checker.

Opening the tool

1. Open the EQLabs Hub and search for Measure (or browse to Design → LevelDesign).
2. Click the tool card.
3. Select actors in the level.
4. Click a measurement button.

Interface tour

Action	What it does
Measure Distance	Distance between two selected actors (or actor pivots)
Measure Bounding Box	Dimensions of selected actor(s) bounds
Measure Path Distance	Total distance walking through every selected actor in selection order
Display Unit combo	Centimeters / Meters / Feet
Copy Results	Clipboard dump of the visible results
Clear Results	Empties the results list
Results list	Per-row: label, value (formatted with unit suffix)

Measurement types

Type	What it measures	Selection requirement
Distance	Pivot-to-pivot distance	Exactly 2 actors
Bounding Box	XYZ dimensions of bounds	1+ actors
Path Distance	Sum of pivot-to-pivot distances along the selection	2+ actors in order

Results list with several entries showing distance / bounding box / path measurements with mixed unit display.

Workflow

Distance between two actors

1. Select two actors in the viewport.
2. Click Measure Distance.
3. Read the value in the results list.

Bounding box

1. Select one or more actors.
2. Click Measure Bounding Box.
3. Result shows X × Y × Z dimensions.

Path distance

1. Select actors in the order you want to traverse.
2. Click Measure Path Distance.
3. Result is the sum of pivot-to-pivot distances.

Switching units

Change the Display Unit combo to convert all displayed measurements. The underlying values are stored in cm and converted on display.

Output

• In-panel results list. Clear via Clear Results.
• Clipboard. Copy Results writes plain text.
• No level edits. Measurement is read-only.

Tips and gotchas

• Distance is pivot-to-pivot. If your actors have weird pivots, the measurement reflects that, not visible-edge-to-edge.
• Path distance is selection-order-dependent. UE doesn’t always preserve selection order; use a single click + shift-click to control order.
• Feet display uses imperial conversion. 30.48 cm per foot.
