land:Pipes

Element information

Content

• Sequence [1..1]
  1. land:Units [0..1]    All angular and direction values default to radians unless otherwise noted. Angular values, expressed in the specified Units.angleUnit are measured counter-clockwise from east=0. Horizontal directions, expressed in the specified Units.directionUnit are measured counter-clockwise from 0 degrees = north
  2. land:Pipe [1..*]    Each Pipe within a Pipes collection element will have a unique "name" attribute.The pipe type is determined by the existance of one of the following elements: CircPipe, ElliPipe or RectPipe.The "startRef and "endRef" attributes reference Struct "name" values.The start and end invert elevations for the pipe are defined in the Invert elements of referenced structures.Since a struct may have more than one Invert element, the Invert "pipeRef" attribute is used to select the correct invert element.
  3. 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.
