Selecting several handles at once

It is possible to select several handles at once so that they can all be moved in one go.
For example the three beams on the right can be extended by the same distance in one go as follows.

Select the parts to be modified.


Hold down the ALT key and window over the required handles.



The selected handles will be represented by a solid square once selected.



Now you can right-click and select Move Special Linear, enter the distances to be moved in the X, Y and Z directions and click Move.





The same can be done where several handles meet at the same place.




Useful applications:
This can be useful for moving column splices for a group of columns.
