ON-LINE REFERENCE DOCUMENTATION CARDINAL SYSTEMS, LLC 386-439-2525 |
Type: Interactive Application
Nodes lines together.
Interactively nodes two lines at their intersect points. The two lines to be nodded are identified by the user. Options include the ability to place node points on each line or to node the lines and break the lines at the intersect points. The elevations of the node points are interpolated based on the slope of the point in front and behind the node points. Z Rules may be applied to the node points.
A batch version of this interactive application is available. See Batch Node (BatNod).

Specifies the break mode when two lines are nodded. Options are “Node only” in which a node point is placed on each line at the intersection and “Break and node” in which the lines are broken at the intersection.
The rule for computing the elevation at the intersection of the two lines. During nodding an elevation for each line is computed at the break point. These elevations are based on the slope of the line segment as determined by the point before and after the break point. The Z Rule determines the action to be taken on these two elevations as follows:
Original elevations – The elevations of the break points is not modified
Mean node elevations – The elevations are averaged and stored for both node points.
Elevation from line 1 – The elevation from the node point on line 1 is used on both lines.
Elevation from line 2 – The elevation from the node point on line 2 is used on both lines.
