MicroStation - Design - Unable to Open--A file MicroStation/J previously opened is now giving error message "unable to open, not a design file" after opening in MicroStation V8. What happened?Version: 07.01.01.57Product: MicroStation J 7.1Area:OpenDGN - Miscellaneous
The file inadvertently was upgraded to V8 format, instead of V7-Read-Only mode and V8 files cannot be read in V7. A workaround is to open file in V8 then do a File > Save As to a V7 design file format.
