TPC has great tools that let you work with both horizontal and vertical alignments.
TPC works with horizontal alignments including horizontal curves and spirals.
TPC is just as comfortable working with stations and offsets as it is with coordinates.
TPC works with profiles and vertical curves.
TPC lets you create cross-sections along with your alignments and plot them separately with grids.
TPC can draw any alignment traverse in plan or profile. You can label stations, elevations, curves, spirals and lots more.
TPC has lots of COGO tools for working with alignments.
