I have a code to analyze interference here is the important part of my code
Public Sub MoveAllToBoundingBoxTest()
Dim oApp As Application
Set oApp = ThisApplication
Dim oAsmDoc As AssemblyDocument
Set oAsmDoc = oApp.ActiveDocument
Dim oAsmCompDef As AssemblyComponentDefinition
Set oAsmCompDef = oAsmDoc.ComponentDefinition
Dim oTG As TransientGeometry
Set oTG = oApp.TransientGeometry
Dim constraints As AssemblyConstraints
Set constraints = oAsmCompDef.constraints
Dim i As Integer
For i = constraints.Count To 1 Step -1
constraints.Item(i).Delete
Next i
Dim l As Integer
l = oAsmCompDef.Occurrences.Count
' Initialize the interference matrices with -1 (unprocessed)
Dim interferenceMatrix() As Integer
Dim interferenceMatrixx() As Integer
Dim interferenceMatrixxx() As Integer
Dim interferenceMatrixNegX() As Integer
Dim interferenceMatrixNegY() As Integer
Dim interferenceMatrixNegZ() As Integer
ReDim interferenceMatrix(l, l)
ReDim interferenceMatrixx(l, l)
ReDim interferenceMatrixxx(l, l)
ReDim interferenceMatrixNegX(l, l)
ReDim interferenceMatrixNegY(l, l)
ReDim interferenceMatrixNegZ(l, l)
' Initialize an array to store occurrence names
Dim occurrenceNames() As String
ReDim occurrenceNames(l)
For i = 1 To l
occurrenceNames(i) = oAsmCompDef.Occurrences(i).Name
Next i
Dim oVector As Vector
Set oVector = oTG.CreateVector(0.00001, 0, 0)
' Loop through all occurrences for X-axis movement
For i = 1 To l
Set oOccurrence = oAsmCompDef.Occurrences(i)
' Store the original position of the current occurrence
Dim originalMatrix As Matrix
Set originalMatrix = oOccurrence.Transformation
' Apply the movement
Dim oMatrix As Matrix
Set oMatrix = oOccurrence.Transformation
oMatrix.Cell(1, 4) = oMatrix.Cell(1, 4) + oVector.X
oOccurrence.Transformation = oMatrix
' Check for interferences on X-axis
Dim oCheckSet As ObjectCollection
Set oCheckSet = oApp.TransientObjects.CreateObjectCollection
Dim oOcc As ComponentOccurrence
For Each oOcc In oAsmCompDef.Occurrences
oCheckSet.Add oOcc
Next oOcc
Dim oResults As InterferenceResults
Set oResults = oAsmCompDef.AnalyzeInterference(oCheckSet)
' Process the interference results on X-axis
Dim oResult As InterferenceResult
For Each oResult In oResults
Dim movingIDX As Integer, otherIDX As Integer
movingIDX = 0
otherIDX = 0
Dim movingNameX As String, otherNameX As String
movingNameX = oOccurrence.Name ' Name of the currently moving occurrence
' Determine the IDs for moving and other occurrences
For j = 1 To l
If occurrenceNames(j) = movingNameX Then
movingIDX = j
Debug.Print "Moving Occurrence: " & movingNameX & " mapped to ID: " & movingIDX
End If
If oResult.OccurrenceOne.Name = movingNameX Then
otherNameX = oResult.OccurrenceTwo.Name
Else
otherNameX = oResult.OccurrenceOne.Name
End If
If occurrenceNames(j) = otherNameX Then
otherIDX = j
End If
Next j
' Validate and record the interference
If movingIDX = 0 Or otherIDX = 0 Then
Debug.Print "Mapping error: one of the occurrences did not match."
Else
If movingIDX > 0 And otherIDX > 0 Then
interferenceMatrix(movingIDX, otherIDX) = 1
Debug.Print "Interference recorded between (moving) " & movingNameX & " and (stationary) " & otherNameX
End If
End If
Next oResult
oOccurrence.Transformation = originalMatrix
Next i
the rest of the code moves the parts on other axes and check for interferences: The code works but with some assemblies i get the error message run time error method analyzeinterference of object assemblycomponentdefinition failed. My hypothesis is that the api has difficulty to read some interferences what do you think ?
