"invalid group code" error
i catched the error "invalid group code" while read the attached file by calling oddbhostappservices::readfile. can anybody help me find out what causes this error? thanks.
attached files
2 blocks in the drawing have acad_roundtrip_xrec xrecord in their extension dictionaries. the records seem to contain invalid data (with group code 152).
the file can be opened in recover mode.
