SA also offers a selection of Copy and Mirror operations .
Options to Copy Objects:
Objects can be copied. The copy is always placed into the active collection. If the collection containing the copied object is the active collection, the object will be renamed as necessary to maintain uniqueness. There are two main methods for copying an object: Copying and then applying a transform (which can be unity to leave the object unmoved), or copying and then applying a point to point translation. Keep in mind that since point groups are objects, copying a point group will duplicate that group of points. However, since the copied points were not actual measured points (after all, they are copies) they will be depicted as constructed points. It is probably most common for copies to be made without applying any transformation so that the copy is in the same position as the original.
Copy Objects then Transform (Ctr+C). This option offers the ability to use the Enter Transform move command to move a copy of the selected objects by the entered transform.
Copy Objects then Translate by Point to Point Delta. This option offers the ability to use the Translate Points to Points Delta command to move the selected objects in 3D by the selected distance and direction defined by the selected points.
Options to Mirror Objects:
Objects can be mirrored (reflected) about any of a frame’s three planes (XY, XZ, or YZ). This is most often used with symmetric parts. For example, if certain nominal features of an aircraft model are only available on the left side, it will need to be mirrored to the right side when it comes time to work on the right side of the aircraft.
You can either create a mirrored copy of selected objects (creates a duplicate, then reflects the duplicate), or you can mirror the objects directly without creating any copies. Mirrored copies are placed into the active collection and are renamed as necessary to ensure uniqueness. An object moved via a mirroring operation will not be renamed at all. Always use care when mirroring—depending on the object being reflected and the plane being mirrored about, the object’s normal may flip directions.
Mirror Source Objects. This operation directly edits the source objects, mirroring them across the selected reference plane.
Selection begins with a frame used to define the mirror plane, followed by the objects to mirror. Any of 3 separate planes can be used based upon the frame selection (XY Plane, XZ Plane, or YZ Plane).
The objects will be moved by mirroring their positions across the selected reference plane.
Mirror Copies of Source Objects. This is a safer option in that it builds a copy of the selected objects prior to performing the mirror operation. This offers the option to delete the mirrored objects and try again if needed.
