DGN2DGD

Use this to import the data contained in a nominated MicroStation DGN file into a Vulcan design database.

Note

Prior to using this option, we recommend that you check that the correct co-ordinate system and units of measurement are being used.

Splines are exported as a polyline of all the points that Vulcan uses to actually draw the spline (not just the control points). Therefore, if a spline were exported from Vulcan and imported back into Envisage, it would be imported as an ordinary polyline.

Usage:

dgn2dgd <dgn_filename> <dgd_filename> [-flags [layer_name]]

<> indicates a mandatory switch.
[ ] indicates an optional switch.

Option

Description

dgn_filename

Refers to the name of the MicroStation DGN file containing the data that you want to import.

dgd_filename

Refers to the name of the design database file that will be used to store the imported data. To create a new design database, enter the name for the new file.

-flags

The -flags for this executable are:

o	Use this to automatically overwrite existing layers.
e	Explode multiline objects.
l	Load all imported data into a single layer.
f	Use feet as the scaling metric (defaults to metres).
i	Ignore units set in the DGN file.
-c	Will use 2D text for constant elevation objects
-2	Will always use 2D text

layer_name

Refers to the name of the layer that will be used to store the imported data. If the nominated layer already exists, and you have chosen to omit the -o switch, then you will need to confirm whether to overwrite or skip the existing layer. This will need to be done for each duplicate layer found.

Type flags without spaces, in no special order, e.g, -oelfi.

Example:

dgn2dgd southarea.dgn allmine.dgd.isis -l south_area
