I want to using routine api_fafa_int() to get the intersection edges, and these edges will be stored for further operation, however, i do not want to modify the both input faces or keep the bulletin records during the operation in api_fafa_int(), is there something i can do?

thank you

Hi

The bulletins that are created during the operation are important because they support the ability to undo (roll back) the operation. Furthermore, most ACIS operations will change the inputs, even if just to calculate lazy data like bounding boxes. This operation is read-only from the geometric point of view. If the application does not implement undo-redo, then setting api_logging to FALSE will result in the bulletins being deleted anyway.

Best regards,

Jeff

thank you.

if undo/redo function is needed in the application, what else can i do then?

because the input face of the body is from a part with its own history stream, and i need to do some operation on the body to get some new entity in another part,

 is there any strategy to accomplish it?

Hi

I'm afraid I still don't understand what you are trying to accomplish well enough to make suggestions. Can you please provide more details?
