ArcGIS Pro 3.3 API Reference Guide
ArcGIS.Core.Geometry Namespace / GeometryEngine Class / Disjoint3D Method
The base geometry.
The comparison geometry.
Example

In This Topic
Disjoint3D Method (GeometryEngine)
In This Topic
Returns true if geometry1 and geometry2 are disjoint in a 3-dimensional manner.
Syntax
```public bool Disjoint3D(
Geometry geometry1,
Geometry geometry2
)```
```Public Function Disjoint3D( _
ByVal geometry1 As Geometry, _
ByVal geometry2 As Geometry _
) As Boolean```

Parameters

geometry1
The base geometry.
geometry2
The comparison geometry.

Return Value

True if the geometry1 and geometry2 are disjoint.
Exceptions
ExceptionDescription
Either geometry1 or geometry2 or both are null.
The method is not implemented for GeometryBag.
Incompatible spatial references between the input geometries.
Either geometry1 or geometry2 is not Z-Aware.
Remarks
Two geometries are 3D disjoint, if they are Z-Aware and don't have any points in common. The geometries must be Z-Aware or an exception will be thrown.
Example
Determine if two Geometries are disjoint
