Xrecord objects are used to store and manage arbitrary data. They are composed of DXF group codes with “normal object” groups (that is, non-xdata group codes), ranging from 1 through 369 for supported ranges. This object is similar in concept to xdata but is not limited by size or order.
Xrecord objects are designed to work in such a way as to not offend releases R13c0 through R13c3. However, if read into a pre-R13c4 version of AutoCAD ® , xrecord objects disappear.
