MOUS_ICO Popup menu: Dialog box

This list gives an overview of all defined calculation points. For each calculation point, the following properties are shown: identity (Calculation point), number of floors (#Floors) in which noise levels are to be calculated, relative or absolute height (Height) of the lowest calculation point, whether the calculation point is active or passive (A/P). and if the calculation point is attached to a building (a * in Att.).

To separate relative from absolute heights for calculation points, a + will be written in front of the height value for relative heights.

In this list there may be selected several calculation points at a time for the functions Set heights, Delete, Active, Passive, and Show selection. If you want to change a calculation point, only one point may be selected.

## Object handling

New point - The dialog box New calculation point appears (see New).

Several points - The dialog box Several new calculation points appears (see New).

Grid - The dialog box Grid appears (see Grid).

Change - The dialog box Change calculation point appears (see New).

Set heights - By clicking this button, a dialog box appears, in which we may enter new heights for each floor for the selected calculation points. This function is especially relevant in the case that we are going to run the calculation with the same heights in several points. We may also enter more floors or delete floors in this dialog box.

Reset text - See Reset text.

Delete - All selected calculation points are deleted.

Active - Sets the selected calculation points active. Only active calculation points are calculated during noise calculation.

Passive - Sets the selected calculation points passive. Passive calculation points are not calculated during noise calculation.

Show selection < - All dialog boxes are closed, and all calculation points selected in the list will be highlighted in red on the screen. We return to the dialog box by pressing <Enter> or <Esc>.

## Window handling

+ The height of the window in the dialog box showing the list of calculation points is increased.

- The height of the window in the dialog box showing the list of calculation points is decreased.

## Status

Number - states the total number of calculation points defined in Novapoint Noise.

In list - the number of calculation points in the filtered list.

Selected - tells how many of the calculation points in the (filtered) list are selected.

## Selection

Select all - All calculation points are selected.

Invert - All calculation points that are not selected are selected, and vice versa.

Reset - All selections are canceled.

From screen < - All dialog boxes are closed, and we may select one or more calculation points by selecting them from the drawing. We get back to the dialog box by pressing <Enter>. The calculation points that are selected from the drawing will now be selected in the list.

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 calculation points are to be shown in the list.

Status - Chooses which calculation points are to be shown in the list. The choices are:

Active and passive: All calculation points

Only active - Only active calculation points

Only passive - Only passive calculation points

Only calculated - Only calculation points that at least once have been calculated for the current alternative

Only uncalculated - Only calculation points that have never been calculated for the current alternative

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:

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

“Point?1*” - all entities with identity having exactly one character between “Point” and “1”, e.g.: “Point01”, “PointA123”, “Point 1”, but not “Point321”.

## Misc.

OK - The dialog box is closed.
