Hi all,

I am trying to use ZOS API to assign the diffraction-based dll for the User Defined Object in Non-sequential mode. I have tried normal ‘Diffraction Grating’ object and it works good, however, for the User Defined Object, it did not work. Could anybody share some insights for me? Thank you!

Part of the code for normal ‘Diffraction Grating’ object: (This works!)

TheNCE.InsertNewObjectAt(1);

o1 = TheNCE.GetObjectAt(1);

o1.ChangeType(o1.GetObjectTypeSettings(ZOSAPI.Editors.NCE.ObjectType.DiffractionGrating));

o1.DiffractionData.Split=ZOSAPI.Editors.NCE.DiffractionSplitType.SplitByDLL;

o1.DiffractionData.DLL='srg_trapezoid_RCWA.DLL';

o1.DiffractionData.StartOrder=-1;

o1.DiffractionData.StopOrder=1;

Part of the code for ‘User Defined Object’: (This  does not work!)

TheNCE.InsertNewObjectAt(1);

o1 = TheNCE.GetObjectAt(1);

o1.ChangeType(o1.GetObjectTypeSettings(ZOSAPI.Editors.NCE.ObjectType.UserDefinedObject));

o1.Comment = 'DiffractionGrating.DLL';

o1.DiffractionData.Split=ZOSAPI.Editors.NCE.DiffractionSplitType.SplitByDLL;

o1.DiffractionData.DLL='srg_trapezoid_RCWA.DLL';

o1.DiffractionData.StartOrder=-1;

o1.DiffractionData.StopOrder=1;
