Chapter 12: Cross Sections and Mass Haul

Create sample lines. Before any section views can be displayed, sections must be created from sample lines.

Master It Open sections1.dwg and create sample lines along the alignment every 50′.

Solution Using the Cabernet Court alignment, sample all data except the datum surface. Create sample lines by station range and set your sample line distance to 50′.

Create section views. Just as profiles can only be shown in profile views, sections require section views to display. Section views can be plotted individually or all at once. You can even set them up to be broken up into sheets.

Master It In the previous drawing, you created sample lines. In that same drawing, create section views for all the sample lines.

Solution Using the Create Multiple Sections command, create section views for all sample lines. Use the Plot All option, and don’t add any labels to the views.

Define materials. Materials are required to be defined before any quantities can be displayed. You learned that materials can be defined from surfaces or from corridor shapes. Corridors must exist for shape selection and surfaces must already be created for comparison in materials lists.

Master It Using sections4.dwg, create a materials list that compares EG with Cabernet Court Top Road Surface.

Solution To create this materials list, you will need to use Cut and Fill criteria. The EG surface will be Surface2, and the Datum will be Cabernet Court Top Road Surface.

Generate volume reports. Volume reports give you numbers that can be used for cost estimating on any given project. Typically, construction companies calculate their own quantities, but developers often want to know approximate volumes for budgeting purposes.

Master It Continue using sections4.dwg. Use the materials list created earlier to generate a volume report. Create an XML report and a table that can be displayed on the drawing.

Solution Use the Cut And Fill table style to display the volume calculations on the drawing. It should be set to dynamically update in the event that the quantities change (if the profile is adjusted or the alignment is moved).
