Creates a version of an AEC file that can be opened in products such as AutoCAD.

You can create a new version of a drawing file with all proxy AEC objects exploded into basic objects. The new version of the drawing loses the intelligence of the custom AEC objects, but the resulting basic objects can be displayed and accessed in earlier product versions when object enablers are not available.

This command is used with drawings created in AutoCAD Architecture and previous releases.

Note: Any changes you make to the new drawing file do not affect the original drawing file.

The following prompts are displayed.

Enter for Filename

Creates a new drawing file with the specified name.

Note: You can use the Prefix option to create a unique file name for this drawing and to prevent overwriting the existing drawing file.


Determines the drawing file format for the resulting drawing file.


Determines how xrefs are treated when creating the new drawing.


Binds all xrefs to the drawing. Layers and other xref-dependent named objects are merged into the new drawing.


Maintains the xrefs as links to other drawings.

Bind Type

Determines how xref-dependent objects are treated when the Bind option is turned on.


Maintains the names of layers and other xref-dependent objects when binding xrefs.


Merges the names of xref-dependent objects into the new drawing without including the original file name.


Determines how blocks within custom AEC objects are treated.


Explodes all block instances within custom AEC objects into basic objects. The resulting basic objects revert to their original properties rather than the properties of the block definitions.


Does not explode any block instances within custom AEC objects. The properties of the block instances are determined in the usual way, depending on how the objects in the blocks were created and the property settings of the layers on which the blocks are inserted.


Specifies the prefix to be added to the current drawing file name.


Specifies the suffix to be added to the current drawing file name.
