Sections from Grid or Triangulation Surface

This command creates a cross section file (.SCT file) from a surface model that is defined by a 3D rectangular grid file (.GRD file) or a triangulation file (.FLT, .TIN). The grid file can be created in the Civil Design module with the Make 3D Grid File routine. The triangulation file can be created with the Write Triangulation File option in the Triangulate & Contour command. This command also requires a Section Alignment (.MXS) file to define the alignment and stations of the sections. The number of section points created is displayed at the end of the routine.

When using a triangulation file, there is an option for whether to link the sections to the triangulation. With the link, the section file will get updated in case the triangulation file is updated. When the link option is set to Auto, the update is done automatically. When the link option is set to Prompt, the program will prompt with a dialog for whether to update the sections when a triangulation change is detected.
