What is an LXFML file?

LXFML files mostly belong to LEGO Digital Designer. LXFML files are XML-based files that store detailed data about LEGO model designs. They are the native format for storing creations in LEGO Digital Designer and are structured using standard XML tags.
These files record information such as brick type, color, position, and how pieces connect. While the file is best opened and rendered in LEGO Digital Designer, it is a plain text file that you can view or even edit with any XML editor.

Purpose: To encapsulate a complete LEGO build layout in a text-based format.
Interoperability: The format is also recognized by third-party tools like the LDraw Converter, which can use the data to convert models for other applications. (LDraw Converter)
Flexibility: Its open XML structure allows for manual tweaks and troubleshooting if needed.
