To specify the offsets as being the same as those between two existing design items, use the Offset menu options to measure the required distances. Use the submenus to specify the type of element you want to measure
from and the type of element you want to measure
to. The choices in each case are:
Select the required options from the Offset menu and, when prompted, pick the two points between which the offset is to be measured. The calculated distances is entered in the
Offset X,Y,Z text boxes automatically.
Click Apply to create the three offset copies, you are prompted to confirm if you want to retain the copies (if it is correct in the graphical view).
Click Cancel to discard any changes and to exit the
Copy with Offset window.
The Model Explorer now displays which elements have now been created and where they fit into the hierarchy.
