Configuring Mapping for DWG to DGN Conversion

Use the DGNMapping command to create, edit, and delete user-defined DGN mapping setups. You can configure DGN mapping setups separately, or during the DGN export process.

The command opens the DGN Mapping Setups Manager dialog box.

To create a DGN mapping setup:

1. Type DGNMapping at the command prompt.

   Alternatively, you can access the DGN Mapping Setups Manager dialog box during the export process: in the DGN Export dialog box, in DWG to DGN Mapping, click DGN Mapping Setups Manager.

2. In the DGN Mapping Setups Manager dialog box, click New.
3. In the Create New Mapping Setup dialog box, do the following:
   • In Name, type the name of the new mapping setup.

4. In the Modify DGN Mapping Setup dialog box, modify the properties and description of your mapping setup.
5. Click OK.

To rename a DGN mapping setup:

You can rename only user defined mapping setups.

1. Type DGNMapping at the command prompt.

   Alternatively, you can access the DGN Mapping Setups Manager dialog box during the export process: in the DGN Export dialog box, in DWG to DGN Mapping, click DGN Mapping Setups Manager.

2. In the DGN Mapping Setups Manager dialog box, select the mapping setup to rename.
3. click Rename.
4. In the Rename Mapping Setup dialog box, specify the new name for the mapping setup.

   Alternatively, you can access the DGN Mapping Setups Manager dialog box during the export process: in the DGN Export dialog box, in DWG to DGN Mapping, click DGN Mapping Setups Manager.

2. In the DGN Mapping Setups Manager dialog box, select the mapping setup to modify.
3. Click Edit.

   The Modify DGN Mapping Setup dialog box appears. You can modify the properties and description of the selected mapping setup.

4. Click OK.

To delete a DGN mapping setup:

1. Type DGNMapping at the command prompt.

3. Click Delete.
4. Click Yes to confirm the deletion. You cannot delete the mapping setup named Standard.

DGN Mapping Setups Manager Dialog Box

The DGN Mapping Setups Manager dialog box groups options for managing mapping setups for DWG to DGN conversions. You can do the following:

• Create new mapping setups
• Rename existing mapping setups
• Edit mapping setups
• Delete mapping setups

Name

Lists the existing mapping setups and the description of the selected mapping setup, if available.

You can sort the list by clicking the column header. Sequential clicks switch between ascending and descending order.

Right-click a mapping setup from the list displays a context menu.

New

Lets you define a new mapping setup.

Rename

Specifies a name for a user defined mapping setup.

Edit

Opens the Modify DGN Mapping Setup dialog box, where you can edit a user defined mapping setup. You can also double-click a mapping setup to edit it.

Delete

Deletes a user defined mapping setup.

Modify DGN Mapping Setup Dialog Box

The Modify DGN Mapping Setup dialog box groups the options for configuring mapping setups. The dialog box contains the following tabs:

• Layer Tab
• LineStyle Tab
• LineWeight Tab
• Color Tab

You can create a new mapping setup by modifying a copy of an existing mapping setup. You can either modify mapping setups manually, or you can import properties from DWG or DGN files.

• lets you import properties from a DWG file. The column displays values from the imported file.
• lets you import properties from a DGN file for the DGN column. The column displays values from the imported file. You can modify cells in this column to customize the mapping setup.

Layer Tab

Lets you map the layers to levels in the DGN column.

• Lists the layers, respectively the levels, from the DWG or DGN file you import.
• For existing mapping setups, the tab displays the properties from the specified mapping setups.

You can only make changes in the DGN column. Double-clicking a cell switches to editing mode. You can type a value or specify one from the drop-down list.

LineStyle Tab

Lets you map each line style from the DWG file to a DGN line style. You can change existing mappings to suit your requirements.

You can only make changes in the DGN column. Double-clicking a cell switches to editing mode. You can type a value or specify one from the drop-down list.

LineWeight Tab

Lists line weights defined in the DWG file and lets you map them to line weights in the DGN file.

You can only make changes in the DGN column. Double-clicking a cell switches to editing mode. You can type a value or specify one from the drop-down list.

Options from the context menu let you copy and paste single or multiple line weights.

Color Tab

Lets you map color values from the DWG file to colors defined in the DGN file. By default, all colors from the DWG file are mapped to their closest suitable color value from the DGN file. You can specify additional color conversion according to requirements.

To add new entries to the color mapping, right-click and select Add Color from the context menu.

Double-clicking a cell switches to editing mode. You can type the color number, specify a value from the drop-down list, or select a color from the Line Color dialog box.

Note: Colors in the DWG column must be unique.

Setup description

Specifies a description for the mapping setup.
