It was not too many versions ago that there was no Flip Face tool at all! At least, on the InRoads front.
We actually have been using InRoads for all projects, including Land Desktop and Civil 3D, by way of LandXML for the DTM, 2D linework for the figures and a custom XML report to make a PNEZD list for point import.
Since Civil 3D 2010, we have begun some processing of Survey in Civil 3D after getting a clean survey in InRoads. Once all edits were completed, we used a new custom XML report that preserves all of the linking codes with the D of the PNEZD and imported them using a custom Linework Code Set that contains all compatible standard InRoads control codes. As it turns out, we seldom use most of the codes that do not equate 1 to 1 between InRoads and Civil 3D.
I should point out that this only works using the "classic" InRoads Survey and not the Open Roads version. They do not provide the same support for custom XML Survey Reports in it and it is really tying my hands.
