--- Creates an extension that contains custom data in a saved view. Extensions allow a saved view to be enhanced with custom data. The extensions have to be defined in a proprietary .JSON schema file. For now, only three extensions are available: ## Extension Schemas The following extensions are available and are shown below in the details sections. The details sections contain the schema followed by an example of that schema. ### Per Model Category Visibility - Schema

Per Model Category Visibility Details

``` [ { "type": "array", "name": "perModelCategoryVisibilityProps", "required": true, "items": { "type": "object", "required": true, "properties": [ { "name": "modelId", "type": "Id64String", "required": true }, { "name": "categoryId", "type": "Id64String", "required": true }, { "name": "visible", "type": "boolean", "required": true } ] } } ] ```
