I remember having exported an entire assembly with all parts in Parasolid and then reimport them in SolidWorks and having the good surprise to see that the custom properties had passed the Export-Import process and were available in the new SolidWorks asm and prt files as in the originals.

But Today, I try to redo the same process and each time I import parasolid to SolidWorks:  the asm and prt file just get the custom properties from the part and assembly templates but the original properties have disappeared

Is there a "good" way to keep custom properties in a  "SolidWorks --> Parasolid --> SolidWorks"  translation ?
