To Update Holes
Click Tools > Intelligent Fastener > Update holes to align the holes to the position of the fastener.
 
* If you set the Creo Intelligent Fastener configuration option USE_EXTERNAL_REFERENCES to NO, the holes in the parts are created without external references. If the position of the fastener has changed, you must update the position of the holes manually.
