A display perimeter written without its own tag reloaded as an ordinary cut, so a saved blank would come back with its outline to be cut. Programs now carry it as :DISPLAYPERIMETER and the reader maps it back, and stored source entities keep the DISPLAY PERIMETER layer so editing the drawing rebuilds the same never-cut outline. Builds older than this read the unknown tag as a cut. Open nests with display perimeters only in builds that include this change.
