This function spaces all selected objects at the same vertical distance.
Firstly, select all objects which are to be vertically positioned.
Then click the
Spread Objects Vertically icon. The objects are
then placed with their centres evenly spaced vertically. The rectangle
which would surround all of the selected objects is the determining
factor for the spacing. LineArt does not take into account the order
in which the objects were created, but considers only their location
in the surrounding frame.
The selected objects are thus distributed with the same vertical distance between their centres.
