Defines options to copy and mirror selected objects.
Copy
Sets a starting point for the operation.
Sets an end point for the operation.
Plane
Plane by Vector
Creates a mirror copy based on the direction of your transformation vector defined by the reference start point and end point. The mirror plane generated is exactly halfway along and perpendicular to the drawn vector.
Plan Plane
Defines the mirror plane as the XY plane.
Elevation Plane: East West
Defines the mirror plane as the XZ plane.
Elevation Plane: North South
Defines the mirror plane as the YZ plane.
Required Relationships
Displays the parent for the copied objects. The current relationships copied from
the source object display. Point to the parent listed under Required Relationships and select Edit 
to modify the required relationship for the copied objects.
You can only modify the required relationship when the Paste in Place option is selected.
Advanced Paste Options
Keep Original Permissions Group
Controls the permission group assignment for the pasted objects. This option is helpful when you are pasting large data sets containing different types of objects (piping, equipment, structure). Here are some important points to remember about this option.
-
When this option is selected, the software assigns all copied objects to the original permission group, as long as you have write access to that permission group.
-
When this option is selected, if you do not have write access or if the permission group does not exist (such as in the case when mirroring and copying from one database to another), then the software assigns the objects to the active permission group.
Optional Relationships
Displays relationships that can be deleted that are not required for the new objects. All optional relationships applied by default to the new Smart 3D objects are taken from the parent object. Some might not need to be applied to the new object. Click Delete All to remove all optional relationships, or edit each relationship individually.
