[huyc2GQZL]

In secondary development, there is already a "DatumUserDefined" object. Does it have a function to switch the "Datum" drop-down box from "Machine Datum" to" PCS (CAD DATUM) "in the image below? I have been looking for a long time. Does anyone know? Thanks!

//I've created this object
DatumUserDefined datumUserDefined = (DatumUserDefined)active_document.SequenceItems.AddItem(PWI_EntityItemType.pwi_ent_DatumUserDefined_);
