REQ: How to convert the track from NFS Shift2 to F1 Challenge 99-02 (F1C)?

I woulda convert the NFSS tracks to F1C.
But I don't know how when many objects are centered to point zero on the XYZ axis...
Could someone of you help me, please?
Thank you very much in the advance!

Always edit the entire track with the objects that compose it, then switch to direct saving for F1C through the software function you use. Never edit anything before converting each object because you risk changing the coordinates of that object. The greater the size of the track and the same are the coordinates of each object used, new objects to be inserted or removed are always performed in a single window and it is always necessary to note the initial coordinates before carrying out any operation, for example the change of image associated with this object.

Many thanks for your advice, De Lacrowe!
