WorldEdit Selection Overlay (Fabric)
Make your WorldEdit selections visible, readable, and predictable.
What is this?
WorldEdit Selection Overlay is a client-side visual addon that shows your selection exactly as it is — before you run any destructive commands.
No more guessing shapes.
No more wrong sizes.
No more accidental //set air.
You see everything in advance.
Why you actually need this
WorldEdit gives you power, but almost no visual feedback.
This mod fixes that:
- See the real shape of your selection
- Read dimensions directly in-game
- Inspect blocks before editing
- Avoid mistakes that cost time
In-Game Preview
The overlay renders your selection directly in the world:
- exact bounds
- real geometry
- clear corner points
Built-in Dimension Ruler
Measure selections like in CAD tools:
- Clean readable size labels
- Always visible from your current angle
- Can follow your camera or stay fixed
Inspect Before You Edit
Open the block viewer and see exactly what’s inside:
- All blocks in the selection (including
air) - Grouped and searchable
- Fast filtering (
#air,#fluid,#solid) - Chunk-aware (loaded/unloaded)
Perfect before using:
//replace//set//stack
