# Object Builder

#### Basic information

**Author:** Bohemia Interactive

**Compatibility:** Arma 3

**Download:** [Part of Arma 3 Tools package on Steam](http://store.steampowered.com/app/233800/)

#### Description

**Description:**

This tool is used to create, edit and configure 3D models made for Arma 3.
Object Builder is the successor to Oxygen 2.

**Notes:**

Buldozer (the viewer) might not work as expected if you run Object Builder from Steam or from [Arma 3: Tools Launcher](../topics/Tools_Launcher.md) if this last was ran from Steam. The best case of use is to run [Arma 3: Tools Launcher](../topics/Tools_Launcher.md) from the installation directory and run Object Builder from it.
It also includes Material Editor (material tweaking) and O2Scripts (automation).

#### Usage

**Line call:** ObjectBuilder.exe

##### How to use it

You can open any supported model using menu File / Open or drag and drop the model file icon into the main window of Object Builder (tip: you may assign P3D file extensions to Object Builder application using Windows desktop).

You can make empty model using menu File / New.

You can save (save as) the file only into the P3D format.

Preview of model can be showed by Viewer Tool (Buldozer).

##### Viewer setup

parameters for the viewer.

You can use **[Buldozer Configurator](../topics/Buldozer_Configurator.md)** or define your settings manually:

Path to viewer (Commands in [] are optional; leave [] away when using that command):
P:\Buldozer.exe -buldozer [-window] [-noland] [-cfg=PathToConfig] [-maxmem=1024]

-window : Starts Buldozer in window instead of fullscreen.

-noland : Buldozer will not load a island.

-cfg=PathToConfig : Forces Buldozer to use a certain config.

To run viewer correctly you need a Arma 3 successfully installed on hard drive. Using P drive tool prepares P: drive with buldozer.exe

**Known issues:** Running Object Builder directly from Steam may prevent attaching of Buldozer. Using shortcut or running directly from app directory is a possible workaround until the issue is fixed.
