Why PVI Prefixes May Be Lost After Editing
The situation described is an anomaly that is unavoidable in the current version. However, it can be very easily avoided by understanding exactly what’s causing the labels to disappear.
Even though you can edit multiple-selected PVI's simultaneously with the ”PVI Edit” command, use caution to avoid potential loss of information:
If the selected PVI labels do not share common prefixes, ASE will not know which prefix to use for all the selected labels. The feature works this way because in some situations, the ability to apply a common prefix to an entire group of PVI labels, is very advantageous because it saves considerable time over singular label editing.
To generate the finished label after editing a group of PVI labels, ASE looks for common prefixes to apply. If nothing has been specified during editing, but there is no common prefix among the selected PVI labels, ASE just draws a blank... Literally.
How To Avoid Losing PVI Prefixes
When selecting PVI labels for manual editing, follow these guidelines:
Select labels that are of the same feature type
Select labels that use common elevation prefixes
Avoid selecting labels from different profile components (L1, CL, etc.)
Select/edit labels one-at-a-time, when in doubt unless all prefixes match
In the dialog, Select labels with the same combination of TC=/FL=/P elevation labels displayed
In the dialog, type a prefix to change the respective prefixes of all selected PVI's
When editing, if there is a variation in values for a given element of the selected PVI labels, the prefixes will not show up in the dialog. That is a warning that the prefixes currently used in each label will be lost after accepting the changes of the edit.
