File exporteren naar DGN

[-Laura-]

Hallo,

Ik wil een AutoCad file exporteren naar een DGN-file.
Als ik dit doe krijg ik echter een scherm waar ik verschillende dingen kan invullen. Er wordt ook gevraagd: "specify seed file" waar ik een ander DGN file moet laden, deze heb ik echter niet.
Iemand enig idee wat voor een DGN-file dit moet zijn?

Laura,
Een seed file hetzelde als template in autocad. Zie onderstaand citaat uit de help van Map 3d 2007

Exporting

Every DGN file requires a seed file to give it default information (similar to the acad.dwg prototype or template file). The seed file controls working units, global origin, the version you want to export, etc. Several seed files ship with Autodesk Map 3D.

The default for a version 7 DGN file is lrgseed.dgn. The default for a version 8 DGN file is lrgseed3d_v8.dgn. Both of these are three-dimensional seed files.

To export to a two dimensional DGN file, or to set a specific global origin or specific working units, reference the file name of the desired seed file. The global origin and units of resolution should be set in a seed file that is appropriate to your Autodesk Map 3D drawing coordinates.

The seed file you use significantly affects the outcome of the export process. If the design plane coordinate bounds in the seed file do not fully contain the extents of the Autodesk Map 3D drawing, Autodesk Map 3D will not export objects. In this case, use a seed file that works for your region and coordinate system. As a last resort, select the driver option Compute Optimal Seed File Parameters.

To change the seed file for a single file

In the Export dialog box, click the Options tab.
Click Driver Options.
In the Design File Output Settings dialog box, under Seed File, click .
Note If you are a limited rights user, be sure that the seed file is in a location where you have access to it.
In the Select Seed File dialog box, navigate to the location of the seed file to use and select the file.
NoteBe sure to specify a seed file designed for the version of DGN you specified in the Export Location dialog box. You cannot use a DGN version 8 seed file when exporting to DGN version 7.
Click Open.
To change the default seed file

Open the mapexport.ini file using a text editor such as WordPad.
This file is in the C:\Documents and Settings\All Users\Application Data\Autodesk\Autodesk Map 3D\R17.0 folder.

Find the section labeled [IGDS] (for version 7 files) or [DGN_V8] (for version 8 files). This is where the default seed file is specified.
Change the default seed file to the seed file you want.
For example: Driver:RUNTIME_MACROS=_SEED,"C:\Program Files\Common Files\Autodesk Shared\GIS\ImportExport\4.0\design\seed3d_ft.dgn" .

Save and close the .ini file.
