This operation enables to create nodes at the intersection of grid lines in the given area of the grid. The elevations are considered as the coordinates of nodes along the Z axis. The created nodes can be used for all operations of input available in the software.
The control of the creation of nodes is performed in the Create Nodes at the Intersection of Grid Lines dialog box. You can create nodes in the area bounded by the specified marks of the grid lines of the beginning – left list, and the end – the right list for each grid and each direction of grid lines of a particular grid. Before specifying the area of the grid where the nodes are created, it is necessary to uncheck The whole interval checkbox in the line corresponding to this grid. Uncheck the Involved in the intersection checkbox if you want to completely eliminate the creation of nodes at the intersection of grid lines.

Figure 1. Grid lines with nodes at the intersections of grid lines
In order to prevent the appearance of duplicate nodes at the intersection of grid lines check the Do not create nodes in the places of other nodes checkbox.
The Create Node’s Group marker allows you to automatically create a node group (with a name that matches the name of the corresponding grid lines).
