What a conversion keeps

Stitches: Every stitch is kept at its exact position. Nothing is re-digitised.
Colours: Kept when the target stores them. DST stores no colours, only where each colour changes, so your machine asks for the threads.
Trims, jumps and stops: Kept, and written the way the target machine expects them.
Objects and lettering: Design programs keep shapes and text as objects. A machine file only holds stitches, so objects become stitches.
