Introduction
The Deleting Features commands remove elements from your GASWorkS model and drawing. They fall into two groups: model features that participate in the hydraulic solution — customers, nodes, pipes, vertices, and valve nodes — and the drawing annotations layered on top of them, such as user graphics, text, tables, saved and marked views, and the color legend.
Deleting a model feature changes the model and its solution, while deleting an annotation affects only the drawing overlay and leaves the hydraulic results untouched. Choosing the correct command for the element you intend to remove keeps the two layers cleanly separated.
Deletions permanently remove the selected item, so confirm your selection before proceeding. Enable Allow Undo Of Data/Graphic Changes if you want to be able to reverse a mistake. The articles below group the delete commands by the kind of element they act on.

FAQ
-
What is the difference between a marked view and a saved view?A marked view is indicated by a cross-hatched area in the GDI Display, while a saved view is a stored set of display limits you can return to. They are deleted with different commands — Delete Marked View / Delete All Marked Views for marked views, and Delete Saved View for saved views. Deleting a saved view does not change the current view in the GDI Window.
-
Does Delete All User Graphics remove my User Text too?No. Delete All User Graphics removes User Images, Lines, and Symbols only. User Text features are deleted separately with Delete User Text (single) or Delete All User Text (all).
-
There are two Color Legend Text items on screen — which one gets deleted?If a second Color Legend Text is displayed, the first Color Legend Text is the one deleted. Re-execute the command to delete the second one.
-
Can I undo a deletion?Yes, if the Allow Undo Of Data/Graphic Changes environment option is selected — click the Undo icon to restore the last data or graphic change. The option is on the Environment data tab of the Options & Settings screen in the Utilities menu.
