Description

Queries the nearest point on a z aware geometry to the input point in 3D space.  Depending on the method of segment extension, the nearest point can also be found on an extension of the geometry.

Remarks

If the geometry is an Envelope and the input point is located within the bounds of the Envelope, QueryNearestPoint3D will return a point on the exterior of the Envelope nearest the input point.
