Is it possible to Re-insert, for-instance a substation design after your LuminRT setup and design is done.
Specially after changes was done to your substation design in microstation or Bentley substation or you want to use the same LuminRT setup for you As-Built presentation.
Can you work in LuminRT with reference files that can be replaced or updated.
Any design changes would best be updated using a re-export to LumenRT. The only external references that can be used are 3SM files. You could export the changes of the design to a format that LumenRT can import such as OBJ.
