When I export step files from zemax they don't appear to be formatted correctly. The header section looks like this - 

ISO-10303-21;

HEADER;

 

/* File generated by HOOPS Exchange Version 22.0.20 */

 

FILE_DESCRIPTION(('HOOPS Exchange Step'),'2;1');

 

FILE_NAME('C:\\Users\\jonms\\OneDrive\\Grad School\\OPTI521\\OPTI421-521_Fall2024_Jon_STEP_3.STP',

'2024-11-24T14:18:02-08:00',

('jonms'),

('Unknown organisation'),

'HOOPS Exchange 2022.0',

'HOOPS Exchange',

'Unknown authorisation');

 

FILE_SCHEMA( ('AP242_MANAGED_MODEL_BASED_3D_ENGINEERING_MIM_LF {1 0 10303 442 1 1 4 }') );

 

ENDSEC;

 

vs from my professor or step files created in solidworks - 

 

ISO-10303-21;
HEADER;
FILE_DESCRIPTION(('STEP AP214'),'1');
FILE_NAME('Cooke 40 degree field modified.stp','2023-09-23T22:31:11',(' '),('ZEMAX'),'Spatial InterOp 3D',' ',' ');
FILE_SCHEMA(('AUTOMOTIVE_DESIGN { 1 0 10303 214 1 1 1 1 }'));
ENDSEC;

 

Any ideas what settings are messed up in my Zemax? I can get the step file to import into solidworks but it isn't quite right.

Hi Subscriber,

Thank you for resching out to us! All the settings are described in our help file: The File Tab » Export Group » CAD Files. Also consider checking or unchecking the Parasoli libraries since this might be another way to properly export your file:

Kind Regards,

Niki

Turning off the parasolid libratries creates a header like this - 

ISO-10303-21;
HEADER;
FILE_DESCRIPTION ((), '1');
FILE_NAME ('C:\\Users\\jonms\\Desktop\\Double Gauss 28 degree field.STP', '2024-11-28T13:21:28', ('Unknown'), ('Unknown'), 'HarmonyWare STEP v2.0.6', 'HarmonyWare Translators', '');
FILE_SCHEMA (('CONFIG_CONTROL_DESIGN'));
ENDSEC;

Still not quite right. 

I have the same settings on Zemax 2023 on my work computer and it works fine. For school we have 2024 R1.03, did somthing change between these 2 versions for STEP files?
