I played with NL and NL2 for a while, and when my plans started to routinely involve phrases like, "Tune the hill so that it gives ejector air for as long as possible," I decided that I'd slug through FVD++. I have tons of questions about the program, but one seems simple. When I import into NL2, should I select the option to heartline the coaster, or does FVD++ take care of that? I know that there is a heartline value in FVD++, but it's not clear to me how the vertices are placed in NL2 based on the track in FVD++. Thanks.
