Summary
The ArcGISProject object provides access to ArcGIS Pro project methods and properties. A reference to this object is essential for most map automation workflows.
Discussion
The ArcGISProject object is usually one of the first object references created in a map automation script because it is the main entry point to access most other objects in ArcGIS Pro. A project is referenced using the ArcGISProject function. Its properties allow you to get or set project settings such as defaultGeodatabase, defaultToolbox, documentVersion, filePath and more. Its methods allow you to manage project items such as updateFolderConnections, updateDatabases, createMap, and createLayout, and copy or delete some project items using the copyItem or deleteItem methods, respectively.
The updateConnectionProperties method is useful for replacing data sources in a project. Data sources can be replaced on the ArcGISProject, Map, Layer, or Table object. See the Updating and fixing data sources help topic for more detailed information and code samples.
The importDocument method allows you to import map (.mxd), globe (.3dd), and scene (.sxd) documents into a project. This provides a mechanism for automating the conversion of these document types into the ArcGIS Pro project. The importDocument method also allows you to import map files (.mapx), layout files (.pagx), and report files (.rptx) into an existing project.
Once you have a reference to an ArcGISProject object, you can access other objects using a number of list functions. For example, you can access a Map object using the listMaps method or a Layout object and a Report object using the listLayouts and listReports methods, respectively.
The following diagram illustrates, along the left side, the use of list functions for navigating and referencing the objects in a project. The diagram is only an example and does not display a complete set of objects and list methods.
The diagram above, along the right side, also illustrates many of the create functions. For example you can use createMap to create a Map object or createLayout to create a Layout object.
Note:
The createGraphicElement, createGroupElement, createPictureElement, and createTextElement methods are also available on the ArcGISProject object because they allow you to create the elements in either a Layout object or a graphics layer in a Map object.
Tip:
When creating elements in a graphics layer in a map, graphic layers are limited to a set number of features and overall size. See Work with graphics layers for more information.
There are a few methods and properties that only work with scripts that are run in the application such as scripts run in the Python window, a notebook, or those associated with a script tool. These are activeMap and activeView properties and the closeViews() method. The activeMap property will return the Map object associated with either an active map view or the active map frame on an active layout view. If these conditions are not met, NoneType will be returned. The activeView property will return either a MapView object if a map view is active or a Layout object if a layout view is active. If no views are active, both properties will return None. These properties will always return a None value when a script is run outside the application, because views are only relevant when the application is open. The MapView object returned from the activeView property is the only way to change the extent associated with a map view. There are multiple functions available on the MapView class that allow you to change the extent, such as camera, panToExtent, ZoomToAllLayers, and ZoomToBookmarks. The closeViews function is useful for closing specific view types in the application. To give focus to a specific view, close all views and use the openView method on the Layout, Map, or Report class.
Note:
Projects can be referenced multiple times but only the first reference can be saved directly because the other references will be opened as read-only. The ArcGISProject object has an isReadOnly property that can be used to determine a project's read state before calling a method such as saveACopy instead of save.
Properties
| Property | Explanation | Data Type |
| activeMap (Read Only) | Returns the map object associated with the focused view within the application. If a layout view is active, it will return the map associated with the active map frame. Note:This property is designed to be run from within the application using a script tool, the Python window, or a Notebook. If a script is run outside of the application, a value of None will always be returned. | Map |
| activeView (Read Only) | Returns a MapView or a Layout, depending on the current view. If the ArcGIS Pro project has no open views, or if the active view is something other than a map view or layout view (for example, a chart, table, Model Builder view, and so on), None will be returned. Note:This property is designed to be run from within the application using a script tool or the Python window, or a Notebook. If a script is run outside of the application, a value of None will always be returned. | Object |
| databases (Read Only) | Returns a list of Python dictionaries, each representing the properties for individual databases in a project. To modify the databases, see the updateDatabases method. | List |
| dateSaved (Read Only) | Returns a Python datetime object that reports the project's last saved date. | DateTime |
| defaultGeodatabase (Read and Write) | The project's default geodatabase location. The string must include the geodatabase's full path and file name. Note:This property can be locked by systems administrators through Application settings. | String |
| defaultToolbox (Read and Write) | The project's default toolbox location. The string must include the toolbox's full path and file name. Note:This property can be locked by systems administrators through Application settings. | String |
| documentVersion (Read Only) | Returns the version of the document based on when it was last saved. Running save or saveACopy will update the document version to match the application version. | String |
| filePath (Read Only) | Returns a string value that reports the fully qualified project path and file name. | String |
| folderConnections (Read Only) | Returns a list of Python dictionaries, each representing the properties for individual folder connections in a project. To modify folder connections, see the updateFolderConnections method. | List |
| homeFolder (Read and Write) | The project's home folder location. The string must include the full path to the desired location. Note:This property can be locked by systems administrators through Application settings. | String |
| isReadOnly (Read Only) | Returns True if a project has already been opened in another instance of the application or referenced by another script. Knowing the current state allows you to determine whether you can save the project, for example, or if you need to call saveACopy instead. | Boolean |
| metadata (Read and Write) | Get or set the project's Metadata class information. Note: Setting metadata is dependent on the isReadOnly property value. | Metadata |

Methods
closeViews ({view_type})| Parameter | Explanation | Data Type |
view_type | A constant that determines the type of views to be closed in the application.
(The default value is MAPS_AND_LAYOUTS) | String |
Sometimes it is useful to clean up numerous open views in the application before opening a specific view to see the resulting view with better focus. The method is limited to closing only view panes associated with a layout, map, or a report. This method will also close table views associated with a "MAP".
Note:
This method is designed to be executed from within the application using a script tool, Notebook, or the Python window. It will have no effect if executed outside of the application.
copyItem (project_item, {new_name})| Parameter | Explanation | Data Type |
project_item | An object reference that represents a supported project item to be copied. | Object |
new_name | An optional string that represents the name of the new project item. If a name is not provided, the default name will follow the sequencing nomenclature, for example, Map, Map1, Map2. | String |
| Data Type | Explanation |
| Object | If a variable reference is specified, the returned object will represent either a layout, map, or report project item. |
createGraphicElement (container, geometry, {style_item}, {name}, {lock_aspect_ratio})| Parameter | Explanation | Data Type |
container | A reference to a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or a graphics layer. | Object |
geometry | The appropriate Point, Polyline, or Polygon object that will be used to construct the graphic element. Page units should be used for layouts and map units should be used for elements in a graphics layer. | Object |
style_item | An optional reference to a StyleItem. The style's intended geometry must match the geometry input parameter. If a style_item value is not specified, a default style item will be applied. | String |
name | An optional string that represents the name of the new GraphicElement. If a name is not provided, the default name value will follow the automatic sequencing nomenclature, for example, Point, Point 1, Point 2, and so on. | String |
lock_aspect_ratio | An optional Boolean that controls how the element can be resized. For example, if the value is True, setting the elementHeight value will also set the elementWidth value proportionally. (The default value is True) | Boolean |
| Data Type | Explanation |
| GraphicElement | If a variable is provided, it will reference the newly returned GraphicElement object. |
This method is located on the ArcGISProject object because the container property allows you to create graphic elements in either a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or graphics layer.
If the element is created using a point geometry, the point location will represent the anchor position and there will be a default size. Later you can resize the element using the elementWidth and elementHeight properties. The createPredefinedGraphicElement method is very similar but it allows you to create common, predefined shapes.
Refer to the GraphicElement class help topic for more information and code samples.
createGroupElement (container, element_list, {name})| Parameter | Explanation | Data Type |
container | A reference to a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or a graphics layer. | Object |
element_list [element_list,...] | A list of elements that will be placed in the newly created group. Note:You can not create an empty group element, there must be existing elements to place in the group. | List |
name | An optional string that represents the name of the new GroupElement. If a name is not provided, the default name value will follow the automatic sequencing nomenclature, for example, Group Element, Group Element 1, Group Element 2, and so on. | String |
| Data Type | Explanation |
| GroupElement | If a variable is provided, it will reference the newly returned GroupElement object. |
This method is located on the ArcGISProject object because the container property allows you to create graphic elements in either a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or graphics layer.
You can not create a new, empty group element. Rather, you need to have existing elements to embed within the group element. If the container is a layout or graphics layer, the group will be created at the root level. If the container references an existing group element, a child group element will be created. The first element in the list will be the first element in the group, the next element in the list will appear below the first element in the contents pane, and so on.
Refer to the GroupElement class help topic for more information and code samples.
createLayout (page_width, page_height, page_units, {name})| Parameter | Explanation | Data Type |
page_width | A double that specifies the width of a layout and is based on the page_units. | Double |

page_units | One of the following page units must be provided to describe the page_width and page_height values.
| String |
name | A string that represents the name of the new layout. If a name is not provided, the default name will follow the sequencing nomenclature, for example, Layout, Layout1, Layout2. | String |
| Data Type | Explanation |
| Layout | If a variable reference is optionally provided, it will represent a reference to the new Layout object. |
This method returns a reference to a new Layout object. If you want to see the layout and activate it in a view, call the openView method on the Layout. The next steps will be to populate it with new layout elements using different constructor methods on the Layout class or the ArcGISProject class.
createMap ({name}, {map_type})| Parameter | Explanation | Data Type |
name | A string that represents the name of the new map. If a name is not provided, the default name will follow the sequencing nomenclature, for example, Map, Map1, Map2. | String |

(The default value is Map) | String |
| Data Type | Explanation |
| Map | If a variable reference is specified, it will represent one of the supported map_type objects. |
This method returns a reference to a new map class. If the script is run within the application, the basemap specified in the project settings will get applied. If the script is run stand-alone, the Topographic basemap will automatically get added.
createPictureElement (container, geometry, path, {name}, {lock_aspect_ratio})| Parameter | Explanation | Data Type |
container | A reference to a Layout object, a graphics layer object in a Map, or a GroupElement object in a layout or a graphics layer. | Object |
geometry | The appropriate Point, or Polygon object that will be used to construct the picture element. Page units should be used for layouts and map units should be used for elements in a graphics layer. | Object |
path | A string that represents the full path and file name of the location of the picture. | String |
name | An optional string that represents the name of the new PictureElement. If a name is not provided, the default name value will follow the automatic sequencing nomenclature, for example, Picture, Picture 1, Picture 2, and so on. | String |

| Data Type | Explanation |
| PictureElement | If a variable is provided, it will reference the newly returned PictureElement object. |
This method is located on the ArcGISProject object because the container property allows you to create graphic elements in either a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or graphics layer.
If the element is created using a point geometry, the point location will represent the anchor position and will be added at full size based on its number of pixels. Later you can resize the element using the elementWidth and elementHeight properties. If the picture is created with a non-rectangular polygon shape, the minimum envelope that encompasses all coordinates will be used instead.
Refer to the PictureElement class help topic for more information and code samples.
createPredefinedGraphicElement (container, geometry, shape_type, {style_item}, {name}, {lock_aspect_ratio})| Parameter | Explanation | Data Type |
container | A reference to a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or a graphics layer. | Object |

| Data Type | Explanation |
| GraphicElement | If a variable is provided, it will reference the newly returned GraphicElement object. |
This method is located on the ArcGISProject object because the container property allows you to create graphic elements in either a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or graphics layer.
If the element is created using a point geometry, the point location will represent the anchor position and there will be a default size. Later you can resize the element using the elementWidth and elementHeight properties. The createGraphicElement method is very similar but it allows you to create custom shapes.
Refer to the GraphicElement class help topic for more information and code samples.
createTextElement (container, geometry, text_type, text, {text_size}, {font_family_name}, {font_style_name}, {style_item}, {name}, {lock_aspect_ratio})| Parameter | Explanation | Data Type |

| String |
text | The text string associated with the element. | String |
text_size | The size of the text in points. | Double |
font_family_name | The text symbol font associated with the element. Note:The value that appears in the Font name drop-down list on the ribbon does not always match the font_style_name property. Variable fonts contain named instances of font styles and also allow customization. Before setting a value, you can set it on the ribbon and verify the property value returned. | String |
font_style_name | The font style name. Depending on the font, the style may include regular, bold, italic, any combination of these, or an extended list. Note:The value that appears in the Font style drop-down list on the ribbon does not always match the font_style_name property. Variable fonts contain named instances of font styles and also allow customization. Before setting a value, you can set it on the ribbon and verify the property value returned. | String |
style_item | A StyleItem object. The style's intended geometry must match the geometry input parameter. If a style_item value is not provided, a default style item will be applied. | String |
name | The new TextElement name. If no name is provided, the default name value will follow the automatic sequencing nomenclature, for example, Point, Point 1, Point 2, and so on. | String |
lock_aspect_ratio | Specifies whether the element can be resized. For example, if the value is True, setting the elementHeight value will also set the elementWidth value proportionally. This setting does not apply to point text. (The default value is True) | Boolean |
| Data Type | Explanation |
| TextElement | If a variable is provided, it will reference the newly returned TextElement object. |
This method is located on the ArcGISProject object because the container property allows you to create group elements in a Layout object, a graphics layer in a Map object, or a GroupElement object in a layout or graphics layer.
If the text element is using a point geometry, the point location will represent the anchor position and there will be a default size. You can resize the element using the elementWidth and elementHeight properties.
See the TextElement help topic for more information and code samples.
deleteItem (project_item)
| Parameter | Explanation | Data Type |
project_item | An object that represents a supported project item to be deleted. | Object |
The item is permanently deleted from the project. Deleting an item may have an impact on other items. For example, if you delete a map that is used in a layout, the MapFrame that references the map will also lose the reference to the map and the map property will be set to None.
importDocument (document_path, {include_layout}, {reuse_existing_maps})| Parameter | Explanation | Data Type |
document_path | A string that includes the system path and name of a document (.mxd, .3dd, or .sxd) or a map file (.mapx), layout file ( .pagx), or report file (.rptx). | String |
include_layout | A Boolean parameter indicating whether the layout from a map document (.mxd) is imported. If set to True, the layout and all data frames are imported. If set to False, only the data frames are imported. This parameter is ignored for other file types. (The default value is True) | Boolean |
reuse_existing_maps | A Boolean parameter to prevent the creation of duplicate maps in the project. If reuse_existing_maps is set to True, it checks the project for the maps referenced in the imported file and only copies maps that don't already exist in the project. There may be cases in which maps have the same name in different imported sources, so you may want to set this value to False. (The default value is False) | Boolean |
| Data Type | Explanation |
| Map | When importing a map document (.mxd), if include_layout is True, it returns a reference to the layout. If include_layout is False, it returns the first map in the map document. It returns the only single map found in a globe (.3dd) or scene (.sxd) document. The corresponding layout is returned with a .pagx file and report with an .rptx file. |
This method imports one document at a time. To import multiple documents, run the method once for each document. A map document (.mxd) always has a layout. While migrating map documents, if you do not want to import the layout, set include_layout=False.
listBasemaps ({wildcard})| Parameter | Explanation | Data Type |
wildcard | A wildcard is based on the label as it appears in the basemap gallery in the application and is not case sensitive. A combination of asterisks (*) and characters can be used to help limit the resulting list. (The default value is None) | String |
| Data Type | Explanation |
| List | Returns a Python list of String objects. |
The listBasemaps method returns a list object even if only one basemap is returned so use an index number to return a String instead. The output from listBasemaps can then be used in the addBasemap method on the Map class.
The following script adds a basemap to a map.
p = arcpy.mp.ArcGISProject('current')
bm = p.listBasemaps('National Geographic*')[0]
m = p.listMaps('Yosemite National Park')[0]
m.addBasemap(bm)listBrokenDataSources ()
| Data Type | Explanation |
| List |
The listBrokenDataSources method always returns a Python list object even if only one broken layer or table is returned.
listColorRamps ({wildcard})| Parameter | Explanation | Data Type |
wildcard | A wildcard is based on the color ramp name as it appears in the application. A combination of asterisks (*) and characters can be used to help limit the resulting list. (The default value is None) | String |
| Data Type | Explanation |
| List | Returns a list of ColorRamp objects. |
It is possible to have multiple color ramps in a project with the same name. It is important that you author your project with color ramp names that can be easily searched using a unique name. An index number can be used to return a specific color ramp. For example, the following line will return the first color ramp object in the list: cr = aprx.listColorRamps("Black*")[0].
listLayouts ({wildcard})| Parameter | Explanation | Data Type |
wildcard | A wildcard is based on the layout name and is not case sensitive. A combination of asterisks (*) and characters can be used to help limit the resulting list. (The default value is None) | String |
| Data Type | Explanation |
| List | A Python list of Layout objects in an ArcGIS project. |
Returns a Python list of Layout objects in an ArcGIS project (.aprx).

| Data Type | Explanation |
| List | A Python list of Map objects in an ArcGIS project. |
Returns a Python list of Map objects in an ArcGIS project (.aprx).
listReports ({wildcard})| Parameter | Explanation | Data Type |
wildcard | A wildcard is based on the report name and is not case sensitive. A combination of asterisks (*) and characters can be used to help limit the resulting list. (The default value is None) | String |
| Data Type | Explanation |
| List | A Python list of Report objects in an ArcGIS project. |
Returns a Python list of Report objects in an ArcGIS project (.aprx).
listStyleItems (style, style_class, {wildcard})| Parameter | Explanation | Data Type |
style | A string that represents either a system style name such as ArcGIS 2D, a personal style such as Favorites, or a custom .stylx file. Note:Styles must exist in the project before they can be referenced using listStyleItems. Custom .stylx files must be loaded and saved in a project. They are referenced by passing in their full path and filename, not by their name only such as with system styles. (The default value is None) | String |
style_class | A string that represents the class of the style items that will be created or modified as they will appear in the Catalog View window.
(The default value is None) | String |
wildcard | A wildcard based on the style item name as it appears in the application. A combination of asterisks (*) and characters can be used to limit the length of the resulting list. (The default value is None) | String |
| Data Type | Explanation |
| List | Returns a list of StyleItem objects. |
It is possible to have multiple style items in a project with the same name. If that is the case, then in addition to the wildcard parameter, you can also use properties like category and tags to validate that you have the style item you want. See the code example in the StyleItem class help topic.
save ()
Saves changes to an ArcGISProject (.aprx). The project is saved and the project variable continues to reference the original ArcGISProjectobject.
saveACopy (file_name)
| Parameter | Explanation | Data Type |
file_name | A string used to save an ArcGISProject (.aprx) to a new file path or file name. | String |
The method creates a new output project file, but the project variable continues to reference the original ArcGISProject object. It does not duplicate all the content within a project folder.
updateConnectionProperties (current_connection_info, new_connection_info, {auto_update_joins_and_relates}, {validate}, {ignore_case})| Parameter | Explanation | Data Type |
current_connection_info | A string that represents the workspace path or a Python dictionary that contains connection properties to the source you want to update. If an empty string or None is used in current_connection_info, all connection properties will be replaced with the new_workspace_info, depending on the value of the validate parameter. | String |
new_connection_info | A string that represents the workspace path or a Python dictionary that contains connection properties with the new source information. | String |
auto_update_joins_and_relates | If set to True, the updateConnectionProperties method will also update the connections for associated joins or relates. (The default value is True) | Boolean |
validate | If set to True, the connection properties will only be updated if the new_connection_info value is a valid connection. If it is not valid, the connection will not be replaced. If set to False, the method will set all connections to match the new_connection_info value, regardless of a valid match. In this case, if a match does not exist, the data sources would be broken. (The default value is True) | Boolean |
ignore_case | Determines whether searches will be case sensitive. By default, queries are case sensitive. To perform queries that are not case sensitive, set ignore_case to True. (The default value is False) | Boolean |
For more detailed discussion, parameter information, scenarios, and code samples, see Updating and fixing data sources.
updateDatabases (databases, {validate})| Parameter | Explanation | Data Type |
databases [databases,...] | A list of Python dictionaries that each contain properties to an individual database. The dictionary keys are defined below.
| List |
validate | If set to True, the database will only be added if the databasePath is a valid database. If it is not valid, the database will not be added and the function will return the dictionary as an invalid database. If set to False, the method will add all the databases to the project, regardless of whether the database can be connected to. (The default value is True) | Boolean |
| Data Type | Explanation |
| List | A list of invalid databases. |
To update a project's databases, you must set the entire list of databases at once. You cannot add, remove, or update a single database at a time. You can either build a new list from scratch or you can modify the list returned by the databases property and push the entire list back to the project using the updateDatabases method.
updateFolderConnections (folder_connections, {validate})| Parameter | Explanation | Data Type |
folder_connections [folder_connections,...] | A list of Python dictionaries that each contain connection properties to an individual folder. The dictionary keys are defined below.
| List |
validate | If set to True, the folder will only be added if the connectionString is a valid path. If it is not valid, the folder will not be added and the function will return the dictionary as an invalid folder. If set to False, the method will add all the folders to the project, regardless of whether the folder is valid. (The default value is True) | Boolean |
| Data Type | Explanation |
| List | A list of folders that do not have valid connections. |
To update a project's folder connections, you must set the entire list of databases at once. You cannot add, remove, or update a single folder connection at a time. You can either build a new list from scratch or you can modify the list returned by the folderConnections property and push the entire list back to the project using the updateFolderConnections method.
Code sample
The following script demonstrates how to import documents into an existing ArcGIS Pro template project. It also sets up some of the default project settings and saves the result to a new project file.
import arcpy
#Reference a blank, template project on disk
p = arcpy.mp.ArcGISProject(r"C:\Projects\blank.aprx")
#Import documents set up default GDB and toolbox
p.importDocument(r"C:\Projects\YosemiteNP\Documents\Yosemite.mxd")
p.importDocument(r"C:\Projects\YosemiteNP\Documents\Yosemite_3DViews.3dd")
