You can use sections to examine existing and proposed surface elevations sampled across an alignment at defined station intervals.
In AutoCAD Civil 3D, section data is defined and displayed using sample lines, sections, and section views, all of which are managed through a collection called a sample line group. An alignment can have more than one sample line group associated with it, each having a unique set of sample lines and sections.
For overview information about AutoCAD Civil 3D objects, see Understanding Civil 3D Objects.
Topics in this section
- Sample Line Object
Use a sample line as a linear plan object representing the direction along which sections are cut for a set of specified surfaces.
- Section Object
Use a section object to examine surfaces, corridor models, and pipe networks along a sample line (across an alignment). In AutoCAD Civil 3D, each section is an object.
- Corridor Sections
Use corridor sections to examine the assemblies that make up a corridor model, as well as the surrounding civil objects, such as surfaces and pipe networks.
- Section View Object
Create section view objects to display sectional data in the drawing.
- Section Object Relationships
Since sample line geometry controls where surfaces are sampled to create section objects, sample lines are the parent of the section object.
- Sample Line Groups Collection (Prospector Tab)
Use the Sample Line Groups collection to access the sample lines, sections, section views, mass haul lines, and mass haul views in a drawing.
- Sections Collection (Prospector Tab)
Use the Sections collection to access the sections in a drawing.
- Section View Groups Collection (Prospector Tab)
Use the Section View Groups collection to access the section views in a drawing.
- Sample Line Collection (Settings Tab)
Use this collection in the ToolspaceSettings tree to manage sample line settings, sample line styles, sample line label styles, and sample line command settings.
- Section Collection (Settings Tab)
Use this collection in Toolspace in the Settings tree to manage section settings, section styles, and section label styles.
- Section View Collection (Settings Tab)
Use this collection in Toolspace in the Settings tree to manage section view settings, section view styles, section view label styles, data band styles, group plot styles, sheet styles, and section view command settings.
