## Overview

**Elastic** is a function to create a rubber band effect by adding elasticity to surfaces and inner curves.

## Operation Method

### Surface Elastic

- Select the surface in
**All/ Curves Selection Mode.** - Enter your desired value via
**Right Panel > Properties > Advanced Physical Properties > Elastic.** - Simulate to check whether surfaces with elasticity are shrunk in 3D viewport.

### Inner Curve Elastic

- Select the inner curves in
**All/ Curves Selection Mode.** - Enter your desired value via
**Right Panel > Properties > Inner Curve Properties > Elastic.** - Simulate to check whether inner curves with elasticity are shrunk in 3D viewport.

## Components

### Surface Elastic

**Surface Elastic** is a function for adjusting the elasticity of surfaces. The lower the value, the more it shrinks after simulation.**For example, **a 10 cm square fabric with 40% elasticity shrinks the fabric to 4 cm. The fabric will remain in the same size at 100% elasticity.

Elastic Weft |
Elasticity is applied in the horizontal direction of the fabric. |

Elastic Warp |
Elasticity is applied in the vertical direction of the fabric. |

### Inner Curve Elastic

**Inner Curve Elastic** is a function for adjusting the elasticity of inner curves.

#### Width

This function gives offsets to both sides around the inner curve for a thick elastic band effect.**For example,** entering 2.5 cm for the width will produce 2.5 cm offsets on both sides centering on the inner curve to create a 5 cm thick elastic band.

#### Strength

**Strength** is a function for setting the strength of elasticity.

The higher the value, the less it is affected by external factors, thus giving stronger features for maintaining the applied elasticity. The lower the value, the more it is affected by external factors, thus having weaker features for maintaining the applied elasticity.

#### Ratio

You can set the ratio of elasticity to apply to inner curves. The lower the value, the more it shrinks after simulation.**For example,** a 10 cm inner curve with a 40% ratio will shrink to 4 cm after simulation.
