Utilities
Find/Replace Name... (Part/Packet/Sheet/CAM Level)
This command displays the Find/Replace Name References Form. It allows you to specify an old/new file name and old/new object name. If a field is left empty, it is ignored. When you press OK or Apply, all references to the specified file or object name are changed to the new names.
All components of an assembly are traversed as well as all sheets within a drawing packet. Entities that reference objects by "file,name" are components, 3D drawing views, external reference geometry, assembly alignment constraints and any history operation that records a pick on geometry residing outside of the parent part (i.e. external/extended pick).
When you rename an object at the Root
Object Level, VX automatically updates all references to the object
within the parent file, but it doesn't traverse any linked objects that
reside in another file. You
have to go to those external objects and use the Change
Part command or use this command where-ever you want to update references
to the renamed part. Be
sure to review the Notes section
below.
Search
Indicates the VX files to be searched. See also VX Search Paths Form.
Find but do not replace
Check this box to locate the VX files but not to change them.
New Version
This option can be used when PDM (Product Data Management) is enabled. Refer to the PDM Tab of the VX Configuration Form for more information.
If a new "File Name"
is specified along with "New Version",
VX replaces all references to the old file with the specified version
of the new file. VX
assumes that the specified file version exists. The
old file is un-mapped even if changes have been made to it. The first
time the new file is accesses, VX will search the local user directory,
then the directories specified by File
Search Paths... and
then the active PDM vaults, if any.

The Change
Part command allows you to modify the
reference to a part component by component (or view by view in drawing
sheets). Change
File/Object References (this command)
is a way to globally update all references to a part throughout a part
and its components, as well as file and object names referenced by the
Link
Manager.
When you are inside of a part and you change its
name using the Part
Attributes Form, the entire part and
its components are searched for all references to the old name, which
are upgraded to the new name. This
includes any extended pick paths that begin with that part.
However, you have to use the Change
Part or Change
File/Object References (this command)
to update other parts and drawings, if desired. Change
Part is the easiest way to change the
part associated with specific components. Change
File/Object References (this command)
is the best way to do a global "search and replace" within a
part, assembly or drawing packet.
