Hi,
I have 25000 dgn files and I want to convert all of them into a single shape file and want to add the following attributes in the shape file
I would like to convert only the line geometry from the dgn files.
Please help

Regardless of the output format, you need to expose the following two format attributes in the DGN reader: "fme_basename" = dgn filename (without the extension), and "igds_level_name" = the layer name. If you need the full filename with path, you need to expose "fme_dataset" as well.
You can e.g. use the AttributeManager to rename them before output.
Use the GeometryFilter to only retain the line geometries.
You can select multiple folders or directories for your dgn files like this, that way you don't have to use any additional functionality:
For example, this will read all the *.dgn files in any subdirectory under C:\Temp
C:\Temp\**\*.dgn
Depending on the volume of the source data, I would prefer another format than shape, in which you can insert records instead of completely overwriting it. Geopackage, geodatabase, postgis, etc.
I think there are roughly 2 ways to do this:
You can always start with trying to do it using one workspace and convert to the workspacerunner alternative when it does not work.

1. Take idgs as reader.
2. Expose required attributes (like dgn name & levels) - attributeexposer
3. Use transformer 'geometryfilter' to filter only 'lines'
4. Use writer gdb ( as you have lot of files)
