Choose a Seed File

ExPLANT-I needs a "seed file" which is a .dgn used as a header for all the generated dgn files, and contains settings such as the units to be used in the dgn file.

You can supply ExPLANT-I with a seedfile in any of three ways:

• You can use the 'seedfile' '<filename>' export option command in Design to set the path of the seed file (note that the path of the file is needed, not the path of the folder, as in the case of the environment variable). For example:

  export option 'seedfile' 'C:\seedfiles\seed1.dgn'

  This is particularly useful if you use different seed files for different exports.

• If the 'seedfile' export option is not set, then ExPLANT-I will look for a file named seed3d.dgn in a folder or search-path set in the environment variable SEED3D_DIR.

• If neither of the above is set, then ExPLANT-I will look for a file named seed3d.dgn in a folder or search-path set in the environment variable PDMSEXE. Such a seed-file is installed there with the product.

  The latter two options are particularly useful if you wish always to use the same seed-file. In that case you can place the file in a location in your PDMSEXE search path, or set SEED3D_DIR in your .bat file.
