Hi,

I have published a new detailed blog article with several macro code examples to cover all the aspects of working with custom properties from the API: SOLIDWORKS Custom Properties Automation 

• Examples on how to read and write general, configuration specific and cut-list custom properties
• Explanation and differences between cached custom properties and resolved custom properties
• How to handle the custom properties modification event (including the workaround for the issue when standard events are not raised: AddCustomPropertyNotify, DeleteCustomPropertyNotify, ChangeCustomPropertyNotify)
• Reading and writing the data into the summary info page
• How to work with custom properties from the Document Manager API
• What are invisible custom propery and how to read ones and create new one

Please let me know if you have any questions or feedback.

Thanks,
Artem
