List of Options

The following options are displayed.

Name

Identifies the DGN file you have selected to attach.

Browse

Opens the Select Reference File dialog (a standard file selection dialog box).

Select a design model from the DGN file

Displays all of the design models that are found in the DGN file. If the DGN file only contains a single design model, that model is listed.

If the DGN file contains multiple design models, only a single model can be selected for attachment. The first model in the list is selected by default.

Conversion Units

Matches the DWF files’s drawing units to the master units and sub-units specified in the DGN file. For example, if the DGN file has master units set to meters, and sub-units set to millimeters, and you want the DWG to be set to millimeters, select sub-units in the Attach DGN Underlay dialog box.

Master Units: Matches the DWG drawing units to the master units set in the DGN file.
Sub Units: Matches the DWG drawing units to the sub- units set in the DGN file.

Path Type

Selects the full (absolute) path, the relative path to the DGN file, or No Path, the name of the DGN file (the DGN file must be located in the same folder as the current drawing file).

NoteThe Path Type group is disabled when you’re attaching a DGN file that is stored on the Vault client server. This information is automatically entered by the Vault.

Insertion Point

Specifies the insertion point for the selected DGN file. Specify On-Screen is the default. The default insertion point is 0,0,0.

Specify On-Screen: Directs input at the Command prompt or the pointing device. If Specify On-Screen is cleared, enter the insertion point in X, Y, and Z.
X: Sets the X coordinate value.
Y: Sets the Y coordinate value.
Z: Sets the Z coordinate value.

Scale

Specifies the scale factor of the selected DGN underlay.

If INSUNITS is set to “unitless” or if the underlay does not contain resolution information, the scale factor becomes the underlay width in AutoCAD units. If INSUNITS has a value such as millimeters, centimeters, inches, or feet, and the underlay has resolution information, the scale factor is applied after the true width of the underlay in AutoCAD units is determined.

Specify On-screen: Allows you to input at the Command prompt or the pointing device. If Specify On-Screen is cleared, enter a value for the scale factor. The default scale factor is 1.
Scale Factor Field: Enters a value for the scale factor. The default scale factor is 1.

Rotation

Specifies the rotation angle of the selected DGN underlay.

Specify on-screen: If Specify On-Screen is selected, you may wait until you exit the dialog box to rotate the object with your pointing device or enter a rotation angle value at the Command prompt.
Angle: If Specify On-Screen is cleared, enter the rotation angle value in the dialog box. The default rotation angle is 0.

Show Details

Displays the DGN file path.

Found In: Displays the path where the DGN file is located.
Saved Path: Displays the path that is saved with the drawing when the DGN file is attached. The path is dependent upon the Path Type setting.
