What type of data is a grid surface created from?

A grid surface is made up of elevation points on a regularly spaced grid. Rather than creating more or less 3D faces based on source elevation data (as in the TIN surface), a grid surface will have a pre-defined number of faces based on the desired grid spacing.

What is grid surface?

A grid surface comprises points that lie on a regular grid. You can create a grid surface or import it from a DEM file. Use grid surfaces for: Mapping more uniform surfaces with evenly distributed sample data.

How do I compare surface volumes in Civil 3D?

Right-click the volume surface in the Volumes Dashboard and click Properties. Select the Range Interval with Datum option when creating the ranges. The elevation analysis is displayed in the drawing using the style you selected above. The bounded area is added beneath the volume surface in the Volumes Dashboard.

How do you find the volume of a surface in Civil 3D?

The newly created volume surface appears in the viewer. To see the details, right-click the volume surface in the Prospector tree and choose Surface Properties. The Statistics tab shows the Volume details, which are dynamically linked to the compared surfaces.

What is a CAD surface?

A surface is a 3D object that is an infinitely thin shell. There are 2 types of surfaces: procedural and NURBS. Procedural surfaces can be associative, maintaining relationships with other objects so that they can be manipulated as a group.

What is volume base surface Civil 3D?

Calculating volumes and creating volume surfaces. Civil 3D can calculate the volume between two surfaces that share the same geographic area. This is a common operation when you have an existing ground surface and a surface of your proposed ground, such as a pond, parking lot, or road design from a corridor.
