ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Core.CIM Namespace / CIMVoxelPlane Class / Normal Property
Version

Normal Property (CIMVoxelPlane)
Gets or sets the direction vector of the plane, which is a unit vector representing the normal to the plane.
Syntax
public MapPoint Normal {get; set;}
Remarks
This vector is perpendicular to the plane you are defining, and it points in the direction of what you want to remove with the plane. The X, Y, and Z values should all be between 0 and 1. For example a Normal of (0,0,1) is pointing away from the earth's surface, and this defines a horizontal plane.
