PREVIOUS I USED ETABS V16 AND EXPORTED .MDB FILE TO IMPORT INTO RCDC AND DESIGN COMPONENTS.NOW I HAVE UPGRADED MY ETABS TO V17 AND I AM UNABLE TO EXPORT AND CREATE .MDB FILE. FIRST OF ALL MY ETABS DOES NOT RESOND WHILE EXPORTING AND ALSO RCDC IS UNABLE TO READ THE FILE. ONE MORE THING IS HOW TO LINK RCDC WITH ETABS V18. AS ETABS V18 EXPORTS IN .ACCDB FORMAT AND NOT .MDB.
