User Tutorial Guide: All about Defining Civil 3D surface Boundary

Introduction to Civil 3D Civil 3D surface Boundary

Firstly, what is a Civil 3D Surface Boundary ? Well, let's find out in this online training course. Certainly, this step by step tutorial is a part of the Civil 3D essentials book and how-to manuals.

Working with Civil 3D surface Boundary? 

It is often essential to limit a surface within a defined boundaryThis allows you to focus on the area of interest. It also helps allocate more computer processing power to the actual required work. Indeed, boundaries help limit Civil 3D's calculations to a smaller surface area. This is especially important as Civil 3D is still a graphics intensive software.

To add a boundary to the surface:

  1. Expand the Existing Ground Surface definition.
  2. Right-click on Boundaries in the definition.
  3. Select Add.
