Where have you found it useful to re-bless or re-construct* an object?

I anticipate two scenario types:
1) re-using the object's data structure (different class)
2) re-initializing some or all object data (same class, call constructor again)

An explanation of what useful purpose is served, or what this transformation represents, would also be insightful. Thanks!
