Specifies the import settings for a DGN file.
The following options are displayed.
Select a Design Model from the DGN file
The DGN design model that you select is imported into the model space of your current DWG file.
V8 DGN files might contain multiple design and sheet models. A DGN design model is equivalent to model space, and a DGN sheet model is equivalent to paper space. Because a DWG file can have only one model space, you need to select the design model in the DGN file that you want to import.
If a design model is selected and is referenced into a sheet model, then the sheet model is also converted as one or more layouts in the DWG file. Only the sheet models that reference the primary design model are imported. These sheet models are translated to paper space layouts, and will include layout viewports that display each reference to the primary design model.
Controls how DGN references are handled in a DWG environment.
Any DGN files are supported as references. These file types include, but not limited to, these extensions: .dgn, .dwg,.cel,.s,.h, .cgm,.rdl,.d files. However, DXF files are not supported and are ignored.
All referenced DGN design models, including nested references, are converted into individual DWG files and attached as xrefs in model space.
The nesting relationships of these references are maintained. DGN design model references that reference the primary DGN design model, also called circular references or self references, are handled by creating a separate DWG copy of the DGN design model and attaching it to the primary DWG as an xref. Design model references to sheet models, and sheet model references to other sheet models are not supported and are ignored. Unique names for the referenced DWG files are generated by appending the model name to the design file name separated with a dash (-). If necessary, the resulting DWG file names is truncated and one or more of the last characters might be replaced with numerals to make the file name unique.
With the following set of options, you can choose whether or not to overwrite external reference files:
Select the appropriate conversion units for the translation. The imported DGN file contains working units (imperial or metric) called master units and sub-units. The selected working units (master units or sub-units) are converted one-for-one into DWG units.
Explode Text Node to Text Elements
Text node elements in a DGN file are multiple lines of text stored as one element, and are similar to MTEXT objects. Check this option to maintain text which follows a path.
When cleared, multiple lines of text are maintained as a single multiline text object.
When checked, multiple lines of text are separated into individual text objects. Select this option to maintain visual fidelity when you import a DGN file that includes text created along a curved path. The first character determines the location and rotation of the text object.
Translate DGN Properties to DWG Properties
Selects and manages the mapping setup used on the current DGN import.
Opens the DGN Mapping Setups dialog box where new mapping setups can be created and existing mapping setups can be renamed, modified, or deleted (see DGNMAPPING).
