OCAD Course Setting files can be saved in a previous OCAD versions (9, 10, 11 or 12) if the file passes the Compatibility Check.
Course setting files containing relay or one-man relay courses cannot be saved in a previous OCAD version. OCAD 12 is using a better distribution for relays and one-man relays variations. As a consequence relay and one-man relay courses are not compatible with previous OCAD versions.
The following features are not known in older OCAD versions and will be deleted:
- Option 'Full stop behind control number' (OCAD 9)
- Option 'Number of start' (OCAD 9)
- Control description anchor (OCAD 9 and 10)
