land:Structs

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:Struct [2..*]    Each Struct within a Structs collection element must have a unique "name" attribute.The structure type is determined by the existance of one of the following elements: CircStruct or RectStruct.The Center element will contain the "north east" coordinate text value or a CgPoint "refPnt" attribute.Each Invert element contains a "refPipe" attribute to reference a Pipe element "name"
  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.
