I want to import around 100 dgn files into one dwg. I have autocad map 2010 and 2009 and understand you can import a dgn under==>Map==>Tool==>Import. But this only allows you to import one at a time. I want to know if there is a way of importing them all at once. Kind of like the way you can select multiple dwf files in exrefs and then bind them all. The only thing is that when you add a dgn file through an external reference, it wont let you  select more than one at a time and also doesn't allow you to bind it. I also know you can import it through cad, but it puts each dgn into its own separate dwg and i don't feel like saving out 100 dgns to dwgs.

You can use a script (and a batch script program like ScriptPro) to perform an automated MAPIMPORT/SAVE command sequence.
