Hi Amit,

 

I don’t seem to be able to reproduce the issue. Assume the following system before interactive extension connection with Angle field type and a finite OBJECT Thickness:

Then, the system, upon connection, remains the same for me:

As a sanity check, I ran the following command, which is True:

TheSystem.SystemData.Fields.GetFieldType() == ZOSAPI.SystemData.FieldType.Angle

Would you be able to share your code and tell us what version of OpticStudio you are using?

Take care,

 

David

Hi David,

 

thank you for your response.

Interactive connection (connected) with field setting definition showing object height as the Type

 

Unfortunately I am not able to attach my code as a file so I am just pasting the script:

Hi Amit,

 

I think the issue is that you are running a Design Lockdown. Please read this excerpt from the Help File about the Design Lockdown tool:

A number of steps are generally required to take a system designed in sequential mode into a production system.   In particular all idealized inputs of the system must be converted into real manufacturing inputs.  The Design Lockdown Tool automates this conversion by:

...

Switching from the use of image-based field point definitions (if they are being used) to object-based definitions.  The primary wavelength is used for this conversion. 

• For finite conjugate systems, Object Height is used as the field definition. 
• For infinite conjugates, Angle is used as the field definition, unless the system is already using Theodolite Angles. 
• Systems with multiple configurations will not be converted to object-based field definitions; any analysis features or conversion to non-sequential should be manually verified if the sequential system is defined with image-based field definitions. 

Hope this helps. Take care,

 

David

Dear David,

 

wow, thankyou. That was overlooked by me.

Thank you for pointing it out.

 

Best regards,
Amit
