The Selection object allows the PML user to interact with the 3D graphical selections set. It is not reliant on AVEVA E3D Design being in graphical mode - the selection set can be created and manipulated in TTY mode, and thus can be used in regression tests.
Only significant elements can be in selection sets. The definition of what is significant varies between graphical interaction modes:
-
In Design navigate mode, all database elements are significant.
-
In Model Editor mode, then only those database elements defined in the Model Editor definition are significant, and some non-database elements.
-
In Draw mode, only drawlist elements are significant.
Most methods look for the 'highest significant element' - they climb up the ownership tree looking for significant elements, until the value of 'scope' is reached - the nearest significant element below this ceiling is used.
