This article provides key points of simulation.


The simulation will apply gravity and drape pattern pieces in the 3D window. When the simulation is on, patterns will fall towards the ground and drape on the avatar. At the same time, existing seamlines will be gathered. Before you turn on the simulation, make sure that your patterns are arranged and sewn properly. Simulation is the first button in the 3D toolbar.

Three types of Simulation

There are three types of simulations: Fast (GPU), Normal (Default) and Fitting (Accurate Fabric).

Fast (GPU)
In this model, the simulation is running on your graphics card instead of your CPU. This is the fastest one and is very useful during the draft phase of your garment.

Normal (Default)
In this model, the simulation is running on your CPU. This simulates fabric accurately with comparatively fast speed.

__Fitting (Accurate Fabric) __
Fitting (Accurate Fabric) is meant to be used on the finished garment with high resolution and there’s no more adjusting to do with. This is the most accurate simulation.


  1. When the simulation is on, its’ icon will turn blue.

Icon changes to blue when the simulation is on

  1. When the simulation is on, the icon of the selection tool in the 3D toolbar changes into a hand shape. The hand tool allows you to move patterns in the 3D window like in real life.
