2.5. Alignment Solver

Alignment Solver is the SurveyTools module for defining and computing horizontal / vertical / cross-section alignment data. It is available in the main window under Calculations. The module provides an ICAD-based drawing engine, GRD point import with TIN surface, full station-equation support, a unified Setout / Measure dialog with multiple modes, and a self-documenting HTML alignment report.
