Feature Representation

Drawing File

FalconView drawing files may contain a combination of one or more of the following six feature types:

  • Line: Each line has a start and end point, and a FalconView drawing file may contain several. Lines also have various attributes associated with them, which describe their draw style.
  • Oval (Ellipse): An oval has an angle, and horizontal and vertical radii associated with it, as well as attributes to describe its draw style.
  • Text: A text feature contains a text string in addition to attributes to describe its draw style and position.
  • Bullseye: A bullseye is represented as several concentric rings radiating out from a single point. It has an associated number of rings, radius and distance between the rings, as well as other attributes describing its draw style.
  • Rectangle: A rectangle has a height and width, as well as position and attributes to describe its draw style.
  • Axis: An axis of advance describes a crosshair, with a width ratio to specify its horizontal and vertical axes.

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes described below. These attributes are common to all feature types:
