MOUS_ICO Menu: Noise > Global settings

The settings in this dialog box apply in general and are not linked to any specific Novapoint Noise object.

Most settings in Novapoint Noise are stored within each drawing. This applies to color settings, text at calculation points, etc. It is recommended to study the section on template drawings in your AutoCAD manual. Use this feature to establish your desired default settings for all new drawings in Novapoint Noise.

Calculation Points

• Default height above ground - The default value for a calculation points height above ground level (in m). The initial value set by Novapoint is 2.0m.

• Distance from facade - The distance from a facade to a calculation point is used when creating noise levels in front of buildings. The default value is 0,5 m according to the Nordic Calculation Method of 1996, but this may vary for other calculation methods. If the value is changed, a control question will appear when exiting the dialog with OK. By answering Yes to the question, all calculation points connected to a building with the existing value for Distance from the facade will be changed and moved according to the new value. Calculation points not connected to a building must be moved manually.

Calculation

• Height difference in profile >  The value used to display a warning if the height difference between two subsequent points in a terrain profile exceeds the given value. The initial value set by Novapoint is 2.0m. The purpose of a warning is to verify and check for unintentional data in a terrain profile not representing the ground surface, e.g., telephone line, etc.

A correct terrain surface is essential to correct noise calculation. If warnings are given, it is recommended to identify the source of the warnings before increasing the value!

• Calculation width - The value determines how far beyond the given profile width the terrain calculation routine shall search for terrain data.

Noise contours and colored areas

Set the drawing order for colored surfaces to bottom.

This setting determines how to handle the drawing order of colored surfaces. Always will draw the surfaces to the bottom of the drawing, Never will draw the surfaces to the top, while Ask will prompt the user each time.

Show profile

• Use VisProf (Windows program) to show terrain profiles - This setting determines how to display terrain profiles generated with the function vnnp_noiseshowprofile. The setting Always will use the Windows program VisProf to display terrain profiles, the setting Never will draw the terrain profiles to AutoCAD, while the setting Ask will prompt the user each time.

Layer names

Defines what layers to use for drawing objects from the dialog boxes in Novapoint Noise.

• Type - Select for what type of Novapoint Noise objects you want to display or change the layer setting.

• Name - The layer name to use for objects of the selected Type.

• Choose layer - Enables the user to select or define a layer name for objects of the selected Type.

• Default layer names - Resets all layer names to Novapoint Noise default settings.

• Layer names for fetching buildings - Launches the Building Layers dialog.

• OK - All changes will be saved and the dialog box will close.

• Cancel - All changes will be ignored and the dialog box will close.
