Import DGN Strings

This dialog is displayed when importing files with the CAD Driver category and DGN Strings data type, and is used to define how layers in the incoming CAD file are interpreted during the import process.

Activity steps

In the Data Import dialog, select the CAD Driver Category.
Select the DGN (Points) Data Type.
Click OK.

The Read drawing file screen displays.
Choose how to import text:
1. To import text as a reference point, select Include text as points. If a text entity is encountered in the DGN file, a new point will be created at the reference location of the text, and the contents of the text will be added to the ANNOT column for that point.
2. To attempt to import text as vector data, unselect Include text as points. If text is not stored in vector format, it will not be imported.
Choose how (or if) to import tag data:
1. Select Include tags as points and Include tag data to ensure a new point is created at the reference location of the tag, and the contents of the tag’s text will be added to the ANNOT column for that point.
2. Unselect Include tags as points and select Include tag data to import tag data in its native format.
3. Select Include tag data to attempt to import tag data or unselect this option to ignore tag data during import.
  
  Although tags have a location in the drawing (the same as text), their main purpose is to attach data to other geometry.
  
  If tag data is found and is associated with other geometry being loaded, the data from the tag will be appended to that geometry’s TAGTEXT column, using the user-specified Multiple text separator to divide entries.
Choose how combined data is managed during import:

DGN entities can be grouped together within cells to indicate some kind of combined context.
1. If Copy cell IDs to points is selected, any elements being loaded which are within a DGN cell will have the ElementID of the cell written to that geometry’s CELLID column, and the Name of the cell written to that geometry’s CELLNAME column.
  
  The CELLID can then later be used as a type of Group column, and the CELLNAME could be used as a Type column.
2. If Copy cell IDs to points is not selected, no additional attribute will occur relating to grouping values.
Choose how cell text will appear:
1. If Copy cell text to all cell points is selected, any text entities found within a cell will have their contents appended to the CELLTEXT column of any non-text entities being loaded, using the user-specified Multiple text separator (see further below) to divide entries.
2. If Copy cell text to all cell points is unselected, CELLTEXT values will not be updated.
Choose how to deal with line styles during import:
1. Select Include line style to write the numeric line style of any imported strings to the geometry’s LSTYLE column.
2. Unselect Include line style to ignore line style information during import.
Specify how the contents of shared cells will be managed:
1. Select Include the contents of shared cells to import data that references shared cells.
2. Unselect Include the contents of shared cells to ignore shared cell contents during import.
Control how cross references will be handled during import:
1. Where outlines are detected in the DGN file being imported (for example, representing different mining methods to ultimately classify resources), you can import the name of this cross-reference by selecting Include cross-reference name.
2. Select Include cross-reference description to import the full description of a cross-reference (e.g. a full description of the mining method represented by outline data).
in DGN files, a data entity can optionally support a linked attribute that will describe a fill pattern for the entity.

Choose how pattern types are managed during import:
1. Select Include pattern types to include this information in your import.
2. Unselect Include pattern types to ignore this data during import.
To include fill color information in your import (for the purpose of mapping to either the default COLOUR settings in your application, or a custom legend), select Include fill colour, otherwise, leave it unselected.
Specify if pattern strings will be imported:
1. Select Include pattern strings to ensure entities classified as being part of a pattern will be imported, and their PATTERN column will be set to 1 (the default value is 0). This can be useful when importing data containing hash patterns, for example.
2. Unselect Include pattern strings to ensure any entities classified as being part of a pattern will not be imported.
Choose how individual text values in data columns are differentiated in the imported file using Multiple text separator.
To control the aspects of the incoming data file that will be affected by your import settings:
1. Select All Levels to ensure that all levels are imported, and affected by subsequent setting changes. Selecting this entry will hide the table of available levels/layers in the selected file.
2. Unselect All Levels to deselect any level (layer) number to filter the data that is imported.
Review the file information at the bottom of the screen.
Click OK.
If importing a file to a Studio project, the Import Files screen displays.
Use the Import Files screen:
1. Choose which Files to create and associate with your project.
2. Confirm the Import Fields for this operation.
3. If required, choose how to Rename Fields during import.
4. Click OK.
  
  Files references are added to the project.
