When I export my vertical geometry to native Geopak I do not see my vertical curve information. I only see VPI station and elevation. I do see the vertical curve information in the OpenRoads Vertical Geometry Report.
Review the Vertical Geometry Report in OpenRoads and verify that the vertical curves are either 'parabolic' or 'asymetrical'. GEOPAK only supports those two types in the native GPK file. If the vertical curve type is 'circular' then they will not export to native Geopak.
