Synchronizing Sheet Set Properties and References

When synchronizing properties or references of an AutoCAD Sheet Set file (.DST), an error "One or more libraries that are needed to access document data are not found" can appear if the viewer pane is active in the PowerUser. This can happen if in the viewer options for the AutoCAD viewer the "Use ObjectDBX" option is checked. As a workaround uncheck the "Use ObjectDBX" option.18743 Sheet Set: Strange error appears on Synchronize references from file
