Change 3d Document Name / ID in Project Map

[Danny Sparks-Cousins]

Can I change the name / id (uName/uiUd) of a 3D Document in the Project Map through the API?

I have tried using ACAPI_Navigator_ChangeNavigatorItem, which returns NoError, but the 3D Document doesn't change in the Project Map

Thanks,
Danny

API_NavigatorItem navItem2Change{};
navItem2Change.mapId = API_ProjectMap;

err = ACAPI_Navigator_GetNavigatorItem(&navItemGuid, &navItem2Change);
 
if (err == NoError) {
 
	navItem2Change.customName = true;
	GS::UCopy(L("PERSPECTIVE"), navItem2Change.uName);
 
	navItem2Change.customUiId = true;
	CHCopyC("D", navItem2Change.uiId);
 
	err = ACAPI_Navigator_ChangeNavigatorItem(&navItem2Change);
 
}
