Create Framme Linkages with FME

FME can be used to write Intergraph Framme linkages. The tricky part is not actually writing the linkages to the graphic DGN elements but figuring out what values to write to the Framme linkages. If you somehow have the correct values from somewhere, then you can use either the FME Workbench or write a FME mapping file to create the linkages.

In this example below, I created an FME mapping file to create DGN line elements with Framme linkages from geometries in a PostGis database table named pipeline. The work is done at the Transformation section of the mapping file as shown in bold below. I am assuming that I have the proper values already calculated and stored as attributes in the PostGis table.
