It provides a small set of legacy Studio utilities for exporting geometry — [PluginManagerInterface:ExportPlace()](/docs/reference/engine/classes/PluginManagerInterface.md) and [PluginManagerInterface:ExportSelection()](/docs/reference/engine/classes/PluginManagerInterface.md) — along with the deprecated [PluginManagerInterface:CreatePlugin()](/docs/reference/engine/classes/PluginManagerInterface.md) method. Calling the `PluginManager()` global requires plugin security. ## Methods ### Method: PluginManagerInterface:ExportPlace **Signature:** `PluginManagerInterface:ExportPlace(filePath: string): ()` Exports all geometry in the place to an `.obj` file. The file is saved to the path chosen by the user in a file save dialog; the `filePath` argument is ignored. *Security: PluginSecurity · Thread Safety: Unsafe* **Parameters:** | Name | Type | Default | Description | |------|------|---------|-------------| | `filePath` | `string` | | Ignored. A file save dialog determines the export path. | **Returns:** `()` ### Method: PluginManagerInterface:ExportSelection **Signature:** `PluginManagerInterface:ExportSelection(filePath: string): ()` Exports all geometry in the current [Selection](/docs/reference/engine/classes/Selection.md) to an `.obj` file. The file is saved to the path chosen by the user in a file save dialog; the `filePath` argument is ignored. *Security: PluginSecurity · Thread Safety: Unsafe* **Parameters:** | Name | Type | Default | Description | |------|------|---------|-------------| | `filePath` | `string` | | Ignored. A file save dialog determines the export path. | **Returns:** `()` ### Method: PluginManagerInterface:CreatePlugin **Signature:** `PluginManagerInterface:CreatePlugin(): Instance` > **Deprecated:** The steps to create a plugin have changed. To learn more, see [Plugin](/docs/reference/engine/classes/Plugin.md). Creates and returns a new [Plugin](/docs/reference/engine/classes/Plugin.md) object, attached to the current place's data model. The returned plugin is associated with the plugin that called this method, so it unloads together with its creator. This method is deprecated. The steps to create a plugin have changed, and new work should use [Plugin](/docs/reference/engine/classes/Plugin.md) directly rather than constructing one through `PluginManager()`. Calling this method requires plugin security. *Security: PluginSecurity · Thread Safety: Unsafe* **Returns:** `Instance` — The newly created [Plugin](/docs/reference/engine/classes/Plugin.md). ## Inherited Members ### From [Instance](/docs/reference/engine/classes/Instance.md) -
