The lxfml file extension is associated with LEGO Digital Designer, LEGO's software for designing virtual LEGO models.

An lxfml file contains a project's model data, including information that describes the locations of bricks in the scene. Because it uses XML, the file can be viewed and edited with a text editor, although manual changes may make the project unusable in LEGO Digital Designer.

The file is also used as the XML component of an lxf archive. LEGO Digital Designer was developed for Microsoft Windows, while BricksViewer provides a multiplatform option for viewing compatible LEGO Digital Designer data.

How to open lxfml file?

On Microsoft Windows, open an lxfml file with LEGO Digital Designer. A text editor can also display the XML contents, but it will not provide a 3D model view.
