igs to asm conversion covers import of IGES 3D exchange format to Solid Edge, or direct conversion between IGES and ASM format. While the later is less likely for whole assemblies, it is certainly doable to import and work with .igs files in Solid Edge. It is extremely unlikely any other tool can help you here, but you can always use some exchange format instead. Numerous tutorials and guides about Solid Edge can be found on the Internet.
