This command removes the xdata (Extended Entity Data) from the
selected entities. Many Carlson routines add xdata to entities in
order to add extra program specific information to them. Carlson
programs use the xdata to make entities more intelligent. For
example, when you draw a centerline (.cl) as a polyline, xdata is
attached to the polyline that stores the reference of the .cl file
name. Then if you double-click the polyline, then the program can
read the xdata to know the polyline is a centerline and launch the
centerline editor. By removing the xdata, the entities revert to
regular CAD entities which is useful if you want to detach these
entities from the program links.
Select entities to remove extended entity data from.
