# GSLayer Grid

*API Collection*

Setting for rounding coordinates on a layer.

## Overview

A layer uses the grid settings of its associated master. The grid determines how layer coordinates are rounded during editing and geometry operations.

Temporary rounding disablement lets an operation preserve exact coordinates while still using the same layer API.

## Topics

- [`GSGridSettings`](/Core/GlyphsCore/GSGridSettings) — Grid settings used to round coordinates.

### Grid

- [`GSLayer grid`](/Core/GlyphsCore/GSLayer/grid) — Current grid settings used for layer rounding.
- [`GSLayer gridMax:`](/Core/GlyphsCore/GSLayer/gridMax:) — Current grid settings, limiting horizontal rounding to a maximum grid length.
- [`GSLayer gridLengthHorizontal`](/Core/GlyphsCore/GSLayer/gridLengthHorizontal) — Horizontal grid length used for layer rounding.
- [`GSLayer gridLengthVertical`](/Core/GlyphsCore/GSLayer/gridLengthVertical) — Vertical grid length used for layer rounding.
- [`GSLayer.temporarilyDisableRounding`](/Core/GlyphsCore/GSLayer/temporarilyDisableRounding) — Temporarily disables grid rounding for layer operations.
- [`GSLayer alignPointToGrid:type:`](/Core/GlyphsCore/GSLayer/alignPointToGrid:type:) — A point aligned to the layer grid for a node type.
