Import Options

After clicking the Options button on the Open File dialog, you can specify different import options depending on the selected format, e.g. a desired coordinate transformation and, for some file formats like AtlasGis, DXF, and SICAD, enter information concerning layer IDs and/or the limits.

CadnaA makes use of the geometrical object types: point, open and closed lines. If any object to be imported does not comply with the geometrical object types in CadnaA – e.g. an open polygon being imported as an area source – it will always be interpreted as an auxiliary polygon, which means it will be irrelevant for the acoustical calculations. In such a case, select the Convert to command from the context menu (see manual "Introduction to CadnaA") to convert the auxiliary polygon to an object of the required type.

Note

In case you intend to import data from third-party software, we recommend to ensure that the object types correspond to the geometrical object types in CadnaA. For example, imported points may get linked to point-objects (e.g., point source, height point, crossing light or tennis source) while imported lines may get linked to line-objects (e.g., line source, road, railway or barrier etc.).
