Application environment settings
Application environment settings are the system wide default settings that are used by every tool.
- From the ArcMap standard toolbar, click Geoprocessing > Environments.
- Click OK to apply the settings or Cancel to leave the settings unchanged.
Default application environment settings
You can create a set of default environment settings that will be used by ArcCatalog and all new ArcMap, ArcGlobe, and ArcScene documents. There are two ways to create and save a set of default environment settings.
Default settings in ArcCatalog
- Open ArcCatalog.
- Click Geoprocessing > Geoprocessing Environments.
- Set the environments to the values you want to use as default.
- Exit ArcCatalog. The environment settings you made are saved.
Any new ArcMap, ArcScene, or ArcGlobe document you create will use the settings you made in ArcCatalog.
Default settings in the ArcToolbox window
- Open the ArcToolbox window by clicking Geoprocessing > ArcToolbox
- Right click the ArcToolbox node and click Environments
- Set the environments to the values you want to use as default and click OK.
- Right click the ArcToolbox node and click Save Settings > To Default
Any new ArcMap, ArcScene, or ArcGlobe document you create will use the settings you saved.
Tool environment settings
Tool environment settings inherit from application environment settings: when you open a tool's dialog box and click the Environments button, the application environment settings are used as the initial values for the tool's environment settings.
- Open the tool's dialog box and click the Environments button.
- Expand the environment categories containing the environment values you want to change. Note that the tool's environment values are initially the same as the application environment settings.
- Type the new values for the environments.
- Click OK to set the value or Cancel to leave the settings unchanged.
Model environment settings
If you execute a model using its tool dialog box, the tool environment settings are passed down to the model. If you execute the model using ModelBuilder, the application environment settings are passed down.
Model environment settings are saved with the model, and because of this, the dialog box for setting model environments is different than the dialog box for setting the application or tool environments. On the model environment dialog box, you check which environment settings you will permanently override in the model. Conversely, unchecked settings will use the value of the passed-down application or tool environment.
Model process environment settings
Model environment settings are passed down to model processes (a model process is a tool plus its data). The dialog box for setting a model process environment is the same as that for setting a model's environments. When the model process executes, the model's environments are passed down to the process and any checked environment in the model process overrides the environment settings passed down from the model environment.
