Select By

The Select By option, in the Edit menu, allows selecting an object by its Material Type, Dataset Value, Area, Length, or Ambiguous Gradient.

Select Connected Arcs

As conceptual models become more complex, and include many arcs (possibly hundreds or thousands), detailed connectivity may not be visibly obvious. This means that it is possible to create or import arcs defining model extents or other features, that appear to be connected, but in actuality are not.

Select Connected Arcs Turning Left

The Select Connected Arcs Turning Left utility allows determining if a conceptual model has gaps in connectivity. The utility is used by right-clicking on a feature arc and selecting a Select Connected Arcs Turning Left submenu. There are two options for selecting the arcs, Forward and Backward. The Forward option follows the direction of the arc and the Backward option follows the opposite direction. This utility selects a string of connected arcs. If more than two arcs connect at a node, the utility selects the left-most turn. In a completely defined polygon, this will select all the arcs in the polygon and traverse right back to the starting arc.

If the Select Polygon tool fails to operate as expected, this utility may identify the gaps in connectivity causing the polygons to not be defined correctly by the build polygon command.
