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.
