Chapter 12

Cross Sections and Mass Haul

Cross sections are used in Civil 3D to allow the user to have a graphic confirmation of design intent, as well as to calculate the quantities of materials used in a design. Sections must have at least two types of Civil 3D objects to be created: an alignment and a surface. Other objects, such as pipes, structures, and corridor components, can be sampled in a sample line group, which is used to create the graphical section that is displayed in a section view. These section views and sections remain dynamic throughout the design process, reflecting any changes made to the sampled information. This process reduces potential errors in materials reports, keeping often costly mistakes from happening during the construction process.

In this chapter, you will learn to:

• Create sample lines
• Create section views
• Define materials
• Generate volume reports
