Hi Kale,
Yes, that is exactly what exporting as OCA is supposed to do. Keep the timing, with information about clones (held drawings and reused drawings) as well as information about layer structure, etc.
If this didn’t transfer over, then something clearly went wrong. I would like to get to the bottom of this.
Would you mind sending me (a link to) both your ap file and your exported OCA data? My email address is the one you got your activation key from. I want to know what went wrong in this process and then I can hopefully help you to get it correctly transferred.
Cheers,
Niels
