Civil Designer maintains a list of point names in use in the project. This list can be used in all dialogs that require you to enter a point name, typically in a filter scenario. Such a dialog has a dropdown list from which you can select a name. This is merely an alternative to typing in the name yourself.
The first three entries are always the familiar ALL, NONE and -- general filters. See the section on Name Filters for their use. Thereafter are the contents of the names list. Selecting an element will cause the dropdown list to close and the selected element to appear in the box.
Maintaining the list in a very large project is a computationally intensive task and would slow down operations if left uncontrolled. For this reason we limit the number of stored point names to 32000, which is the same limit that the standard dropdown list can contain. You can further limit the number of names in the Survey Options page. This page also allows you to toggle whether you want numerical names included in the list. This can be useful where an imported coordinate list has incrementing numbers as the point name, which are somewhat meaningless in a filtering scenario. The default is 200 non-numerical points.
The Names list gets filled every time the screen is redrawn but only after a change in the point database has taken place, for example after a point has been added, removed or edited. In this way, the list contains points that are in the current field of view. With a lot of panning around the project, and no additions or removals taking place, it can happen that there is a point in the field of view but not showing up in a dialog's list. Simply accessing the Survey Options page, closing it, and redrawing the screen will remedy this.
