What is an IFCXML file?
CAD file created in the Industry Foundation Classes XML (IFCXML) XML format, which is an alternative to the plain text .IFC format; uses XML formatting so that the building model data can be exchanged and parsed more easily.
The extra tag data embedded into IFCXML files can sometimes make the file size very large. Therefore, some designers prefer the .IFCZIP file format, which compresses the data using .ZIP formatting and often results in a 90% or greater reduction in file size.
