# Optimizing FabLive Objects

:lock: fabLive3D.**Edit**

## 3D Mesh Simplification Tool

With this tool you can automatically simplify complex 3D Models (.OBJ) to be used in the **FabLives** entity.

## What it does

The 3D Mesh Simplification Tool uses Blender to make the decimation of the faces and create reduced versions of the imported 3D Models.

!!! note
	[Blender](https://download.blender.org/release/Blender2.79/) needs to be installed in the target machine and the path to `blender.exe` must be provided in the settings.

Assuming `blender.exe` already has an entry in the PATH environment variable (Windows) that points to it through the command `blender`, by default the `path=blender` is used.

!!! warning
	Critical Manufacturing recommends that you use Blender v2.79b.

## How to use it

1. Import a 3D model.
2. Adjust the **Ratio** slider (Ratio of simplification) to simplify the model (0% - No reduction, 50% - Number of faces reduced to half, and so on).
3. Find the maximum ratio possible while the model keeps its integrity.
4. When satisfied with the result, **Export** it:
