Problem

Update fields in MicroStation design file do not get updated properly when plotting from Organizer. 

Solution

Make sure the following MS variables are set:
MS_PLT_UPDATE_FIELDS=1
MS_AUTO_UPDATE_FIELDS=ALWAYS

In addition, the file must be opened Read/Write by IPLOT. Set the following in iplot.cfg:
IPLOT_ENABLE_MS_READWRITE=TRUE
