land:Boundary

The boundary region contains a 2D north/east or 3D north/east/elev list of points that define the geometry.

is identified by the "name" attribute.

If the "edgeTrim" attribute is true the faces are trimmed at the boundary edge, otherwise faces are not trimmed

and must exist entirely within the boundary.

Element information

Content

• Sequence [1..1]
  1. Choice [1..1]
     • land:PntList2D    A sequential space delimited list of 2D coordinates with a minimum of 2 points (4 values). It is primarily used for ProfileSurf to hold the list of station/elevations and CrossSectSurf for offset/elevation. Example: "0.000 86.52 6.267 86.89 12.413 87.01 26.020 87.83"
     • land:PntList3D    A sequential space delimited list of 3D coordinates with a minimum of 2 points (6 values). Primarily used to store lists of northing/easting/elevation for Terrain Surface data. Example: "0.000 86.52 50.0 6.267 86.89 50.0 12.413 87.01 50.0 26.020 87.83 50.0"
  2. land:Feature [0..*]    Used to include additional information that is not explicitly defined by the LandXML schema, Feature may contain one or more Property, DocFileRef or nested Feature elements. NOTE: to allow any valid content, the explicit definitions for Property, DocFileRef and Feature have been commented out, but are still expected in common use.Each Property element defines one piece of data.
