Dialog Box

This list gives an overview of all areas defined as hard ground regions. For each area, identity, area, and identification of active/passive status are displayed.

Find it here:

MOUS_ICO Menu: Noise > Hard ground regions > Dialog box

or

nco: Select a hard ground region

MOUS_ICO Popup menu: Dialog box

This list allows the user to select multiple areas for the functions Delete, Active, Passive, and Show selection <. If you want to change the area, only one region can be selected.

AutoCAD does not allow more than 255 lines in a list to be selected at a time. If more than 255 objects are selected, a message will appear at the bottom of the screen, that the list cannot be used directly. This means that more than 255 objects cannot be selected by clicking the list and that the functions Select All, Invert, Reset, and/or From screen have to be applied when more than 255 objects are to be selected. We cannot see from the list which objects are selected, but Selected will show the number, and the functions for the relevant objects do work!

Filter

In the box Filter, we may specify which hard ground regions are to be shown in the list.

• Status - Choose which hard ground regions are to be shown in the list. The choices are:

  • Active and passive: All hard ground regions

  • Only active: Only active hard ground regions

  • Only passive: Only passive hard ground regions

• Identity - A filter based on identity, by stating certain names. The filtering by name follows AutoCAD's wildcard specifications (see Wildcard Characters in the AutoCAD help file).

Example:

• “Water*” - all entities with identity starting with “Water”, no matter what comes after

• “Parking?1*” - all entities with identity having exactly one character between “Parking” and “1”, e.g.: “Parking01”, “ParkingA123”, “Parking 1”, but not “Parking321”.

Misc.

• OK - The dialog box is closed.
