The topological dimension of a geometry.
|esriGeometry0Dimension||1||A zero dimensional geometry (such as a point or multipoint).|
|esriGeometry1Dimension||2||A one dimensional geometry (such as a polyline).|
|esriGeometry2Dimension||4||A two dimensional geometry (such as a polygon).|
|esriGeometry25Dimension||5||A 2.5D geometry (such as a surface mesh).|
|esriGeometry3Dimension||6||A 3D geometry.|
|esriGeometryNoDimension||-1||The dimension is unknown or unspecified.|
Describes the dimensionality of the geometry object. Each dimension corresponds to a direction of orthogonal movement. Therefore, Zero Dimensions describes a point with no extent beyond the point itself. One Dimension describes a line where the dimension of movement extends along the length of the line. Two Dimensions describes a surface where the movement can occur along two parametric orthogonal axes to create an Area. Three Dimensions describes a space with three parametric directions of movement (height, width, and depth). 2.5 Dimensions is a pseudo-dimensional construct that refers to a functional surface, represented by a planar Two Dimensional object with Z attributes. A No Dimensional object (not to be confused with a Zero Dimensional point) is an object for which dimensionality is not properly defined.
