I am running Power InRoads SS2 and using working units in survey feet. It has come to the attention of my client, that my horizontal alignments are not tracking correctly. The problems grows over the course of the project. Are there any know issues with this? We are both set in the same working units/seed files.
Check your Project Defaults (File > Project Defaults). There is a Default Grid Factor. It is used to scale grid coordinates to ground coordinates. This is an excerpt from the Help topic:
Specifies the grid factor. Multiplying a ground measurement by the Grid Factor produces a grid measurement. The Grid Factor applies to horizontal distances, which include arc lengths, tangent distances, chord lengths, radii, stationing, offsets, and slopes/gradients. (Slopes are affected because they involve a horizontal component.) Other computations that involve the Grid Factor include spiral constants, areas, volumes, and rate of change/K values.
If you find its not 1, try setting it to 1. You might want to see if some survey person has dictated that this value is correct, however.
