Civil cell is a collection of civil elements - geometry, templates, and terrain models - which can be placed repeatedly in a design.

The collection of civil elements will have been created relative to one or more reference elements. When you place the civil cell, you choose the new reference elements, and a new collection of civil elements is then created relative to them.

A civil cell can therefore be thought of as a copy of the original collection of civil elements, relative to the geometry of the new reference elements.

Civil cells can be 2D or 3D. They can consist of 2D (plan) elements only, or 3D elements (2D elements with profiles), and can include terrains, linear templates, area templates, and simple corridors.

Civil cells can save a lot of time and effort, because they replicate the complete series of steps needed to create the civil elements.
