Selection and Eyedropper

Selection and sampling are the two key support workflows when you are no longer building from scratch.

Selecting Voxels

Use the Select Tool when you want to isolate voxels for later transforms, operations, or filters.

Selections are useful because many commands in Foxel follow this rule:

• if voxels are selected in the active grid, the command affects only those voxels
• otherwise, it affects the full selected layer or layers

This makes selection the main way to work locally inside a larger voxel layer.

Typical Uses for Selections

• transform only part of a model
• run a filter on one region
• duplicate, detach, or crop a sub-area
• prepare a region for rotation, scaling, or translation

Using the Eyedropper

The Eyedropper samples color and material from existing voxels.

You can:

• activate the dedicated Eyedropper tool
• use Alt + click as a quick sampling shortcut while working

Sampling is especially useful when you want to continue working with colors and materials that are already used in the current model.

Good Workflow

A common pattern is:

1. sample a voxel to pick up its color and material
2. switch back to Draw, Paint, or Material
3. select a region if only part of the layer should be affected
4. continue editing

This keeps your edits visually consistent and reduces manual palette switching.
