Civil3d LandXML surface to Microstation Surface - Help

Posting this here in hopes of finding a CAD/Microstation crossover expert.   The situation:  We have a 5+ mile topographic surface in Civil3d2018 that we need to get into Microstation.  LandXML seemed like the way to get this done but have come to find out that MicroStation doesn’t hold the triangles created as part of the Civil3d LandXML export.  Basically it hold the points but then all of the triangle faces need to be flipped to match the Civil3d surface.  We were hoping one of the long time experts in both could provide us with some guidance.  This should be so easy yet it is so hard....or possible it's our ignorance but we have tried and searched high and low and have not found a solution.
