Calculate stations for BVC and EVC and insert into table 3. Calculate station for high/low point and insert into table (this will be located between stations already entered in table, and not yet highlighted). 4. Calculate ALL tangent elevations, tangent offsets, and curve elevations for stations s. List ALL equations used to do this work. 6. show calculations for Bvo, Evc, and high/low point stationing. 7. show one set of calculations for tangent elevation, tangent offset, and curve elevation.
