Hi crydee, it might be some problem with the join process, if you model has any little tiny degenerate slivery surfaces in it those can tend to confuse the join process.

You can turn off the automatic Join process that happens on IGES import under Options > Import/Export > IGES options > "Join surfaces on import".

Does the doubling go away when you turn the joining off?
