Section Points from Surface Entities

This command creates a section .SCT file in a similar way as Sections from Surface Entities. The difference is that these section points are not connected by a polyline as a surface in Draw Section File. Instead, a point symbol is drawn for each offset-elevation point. First this command prompts for the symbol to use. Next the program asks for the section alignment (.MXS) file to use, then the section (.SCT) file to make or append. Then you select polylines to create the section points from. The intersections of these polylines with the cross sections are calculated and the resulting station-offset-elevations are stored in the section file. The description field for these section points identify them as individual points instead of a surface. The description starts with POINT- followed by the symbol name (e.g. POINT-SPT5).
