I have a question about Item Cards Variable link with documents date card Variable.
I read guide as below:
"When modifying or creating item cards, use the File data card variable option for
mapping file card variables to item cards. This option is available for all control types,
such as check boxes and list controls.
When creating items for configurations, item card values come from the referenced
configuration, or if empty, the custom properties (@ tab). Therefore, if you want item
card values to exactly match configuration values, ensure that all mapped configuration
variables have values by defining those properties as required. Alternatively, do not
use custom properties."
When I modifying or creating item cards, use the File data card variable option for
mapping file card variables to item cards.
I find my mistake:The Variable is a custom properties
I map solidworks part variable to item cards , and part with empty configuration
Any body can show me a guide?
