2. Import LandXML into Civil 3d
3. Import the Civil 3D dwg directly into InfraWorks
1. From Microstation, export to LandXML
2. Import LandXML into Civil 3d

or
4. Export an IMX from Civil 3D and import the IMX into InfraWorks
Please Note: This process only works with 3D objects like surfaces, alignments, etc. and only if the data is Geo-referenced in the correct location in Microstation. If it is not, it will not import into Civil 3D and/or InfraWorks in the correct World location.
