Which of the following conditions must be in place before you can reattach a sketch to new geometry?

To reattach a sketch to new geometry in Siemens NX, it is essential that the geometry has a timestamp that is recognized as occurring after the sketch. This condition ensures that the new geometry is up to date and compatible with the original sketch’s parameters and constraints. When a sketch is created, it may reference existing geometry, and if there have been any modifications or feature creations based on that geometry, those changes need to be accounted for when reattaching the sketch. Therefore, the relationship dictated by the timestamps helps maintain design intent and integrity.

In scenarios where the geometry does not have a timestamp indicating it was created after the sketch, inconsistencies or issues may arise. For instance, if the sketch were to reference older geometry which does not reflect the current design, it could lead to errors when trying to reattach or utilize the sketches effectively. Hence, ensuring the geometry has a timestamp after the sketch is crucial for preserving the link and functionality of the subsequent design process.
