Exchange source file .dat file

I need to exchange the Data File Name of a Source File Object:

 

 

 

I tried to do that by python code:

1import zospy
2
3zos = zospy.ZOS()
4
5oss = zos.connect()
6
7oss.load(‘zmx_file.zmx’)
8
9led = oss.NCE.GetObjectAt(1)
10
11TypeSet_LED = led.GetObjectTypeSettings(zp.constants.Editors.NCE.ObjectType.SourceFile)
12TypeSet_LED.FileName1 = 'filename.dat'

I wrote that code according to section #! [e21s03_py] in example 21 of the ZOS-API Python examples

Apparently, the code does not work.

Did anyone ever manage to exchange source files via python?

Can you provide a code snippet that works?

 

Thanks in advance

Hi ​@dsotm,

Thank you for asking this question and nice to see you’re using ZOSPy!
I checked the example code and this works for me:

1import zospy as zp
2
3zos = zp.ZOS()
4oss = zos.connect("extension")
5
6oss.new()
7oss.make_nonsequential()
8
9# Add new catalog MISC
10oss.SystemData.MaterialCatalogs.AddCatalog('MISC')
11# Set Wave #1 to 0.47 micron
12oss.SystemData.Wavelengths.GetWavelength(1).Wavelength = 0.47
13# Use lumens as the source unit
14oss.SystemData.Units.SourceUnits = zp.constants.SystemData.ZemaxSourceUnits.Lumens # ZOSAPI.SystemData.ZemaxSourceUnits.Lumens
15#! [e21s01_py]
16
17#! [e21s02_py]
18# Add 4 more objects
19oss.NCE.AddObject()
20oss.NCE.AddObject()
21oss.NCE.AddObject()
22oss.NCE.AddObject()
23#! [e21s02_py]
24
25#! [e21s03_py]
26# Set 1st object as a Source File
27Object_1 = oss.NCE.GetObjectAt(1)
28Typeset_SourceFile = Object_1.GetObjectTypeSettings(zp.constants.Editors.NCE.ObjectType.SourceFile)
29Typeset_SourceFile.FileName1 = 'RAYFILE_LB_T67C_100K_190608_ZEMAX.DAT'
30Object_1.ChangeType(Typeset_SourceFile)
31Object_1.GetObjectCell(zp.constants.Editors.NCE.ObjectColumn.Par1).IntegerValue = 5
32Object_1.GetObjectCell(zp.constants.Editors.NCE.ObjectColumn.Par2).IntegerValue = 1000
33Object_1.GetObjectCell(zp.constants.Editors.NCE.ObjectColumn.Par3).DoubleValue = 2.485572
34Object_1.GetObjectCell(zp.constants.Editors.NCE.ObjectColumn.Par8).DoubleValue = 0.47
35Object_1.GetObjectCell(zp.constants.Editors.NCE.ObjectColumn.Par9).DoubleValue = 0.47
36#! [e21s03_py]

Your code seems to be missing this line:

1led.ChangeType(Typeset_LED)

And the specified source file must be located in Zemax/Objects/Sources/Source Files.

Does that help?
