Its GUI is based on Qt4 libraries thus helping the program in running over several platforms with equal ease. It becomes easier for users having experience of similar commercial CAD application to handle concepts which are analogous to AutoCAD. The AutoCAD DXF file format is used internally by LibreCAD for saving and importing files and allowing export to varying file formats.
