Retrieve component based on point3d

I am looking for a way to get all the component objects that have solid material in a certain point3d. Is this possible?

Below is a script that collects the positions of the selected parts. The idea is to create a new point on an offset of the found position and check if there is a component on that spot and get thats component name.

Option Strict Off
Imports System
Imports System.Collections.Generic
Imports NXOpen
Imports NXOpenUI
Imports NXOpen.UF

Module Module1

Sub Main()

Dim theSession As Session = Session.GetSession()
Dim theUI As UI = UI.GetUI
Dim lw As ListingWindow = theSession.ListingWindow

If IsNothing(theSession.Parts.BaseWork) Then
'active part required
Return
End If

Dim numsel As Integer = theUI.SelectionManager.GetNumSelectedObjects()
Dim theComps As New List(Of Assemblies.Component)
lw.Open()
For i As Integer = 0 To numsel - 1
Dim selObj As TaggedObject = theUI.SelectionManager.GetSelectedTaggedObject(i)
If TypeOf (selObj) Is Assemblies.Component Then
theComps.Add(selObj)

Dim pt As NXOpen.Point3d
Dim mx As NXOpen.Matrix3x3
theComps.Item(i).GetPosition(pt, mx)
Dim axisZ As New NXOpen.Vector3d(mx.Zx, mx.Zy, mx.Zz)
lw.WriteLine(theComps.Item(i).Name)
lw.WriteLine( "; Position = " & pt.ToString)
lw.WriteLine( "; AxisZ = " & axisZ.ToString & vbCr)

End If
Next

If theComps.Count = 0 Then
'no components found among the preselected objects
lw.WriteLine("no components found among the preselected objects")

Return
End If

My.Computer.Clipboard.SetText(theComps.Item(0).Name)

lw.WriteLine("Selected Objects: " & theComps.Item(0).Name)

End Sub

Public Function GetUnloadOption(ByVal dummy As String) As Integer

'Unloads the image immediately after execution within NX
GetUnloadOption = NXOpen.Session.LibraryUnloadOption.Immediately

End Function

End Module

If you have an advanced assembly license, there are some functions there that might be useful. It offers such functions as opening components by proximity to a chosen component. I'm not familiar with all the functionality as I don't usually have access to one of these licenses.

If the advanced assembly functions don't have what you need, there is a function in the NXOpen API called .AskPointContainment that will tell you if a given point is in or on the specified solid body. With this function, you could theoretically iterate over all the occurrence bodies in the assembly checking them against the point of interest and report any "hits".
