# 3d Editor: Parameters¶

The Parameters button under the interactive functionality of the 3D Editor offers the user the possibility to perform the set of actions described in what follows, to modify the current view of the material structure under investigation.

Click on the visuals included at the end of each section below to view the animations for the corresponding action.

Editing this numerical text field will modify the radius of the atom spheres accordingly.

## Repetitions¶

The user can edit this second numerical field to repeat the original unit cell a certain number of times in each spatial direction, as defined by a positive integer number.

## Chemical Connectivity Factor¶

The chemical connectivity factor determines whether to draw the bond between two atoms. The bond between two atoms is drawn when the distance is less than the sum of their covalent radii times the chemical connectivity factor.
