Extend Progress Sections

This command extends cross sections that partially cover the design sections to make the sections reach the full extents of the design. This routine applies to a design that is being built in stages. The purpose is to build sections for the surface at a progress stage during construction. The input progress sections for this command are updated and saved back to the progress section file. The progress sections can then be used in Calculate Sections Volumes to calculate progress volumes.

The progress sections will not go beyond the design so that extra volumes are not counted as part of the progress. For example, if a design is in fill and the input progress sections go above the design, then the output progress sections will be brought down to match the top of the design.

Besides prompting for the design sections and input progress sections, the program also prompts for the existing ground sections which are used to limit the progress sections to avoid any extra volumes. For example, if a design is in fill and the input progress sections go below the existing ground, then the output progress sections will be brought up to match the existing ground.

An example application is for road design where the progress is surveyed during construction using GPS to gather points along the road. These points are then used to create a progress section which cover a portion of the road surface but don't tie into the final design. Then this Extend Progress Sections command takes the progress sections from the points and extends the sections to tie into the design.
