Hello everyone
I am in need of assistance in making a macro for CATIA V5
i do not know almost anything about this program but i was asked to make a macro in VBA that when the user runs it will insert the biggest possible sphere inside of the model that was opened,regardless of what model it was opened
Since i dont know anything about this program i tried asking chatgpt and i got this in return
But this code keeps on giving me errors and i really dont know what to do,plus the fact that there is almost no information regarding macros for CATIA on the internet does not really help me in the slightest
If anyone knows anything about this i would appreciate a little guidance
Thank you for reading
I am in need of assistance in making a macro for CATIA V5
i do not know almost anything about this program but i was asked to make a macro in VBA that when the user runs it will insert the biggest possible sphere inside of the model that was opened,regardless of what model it was opened
Since i dont know anything about this program i tried asking chatgpt and i got this in return
Code:
Sub InsertBiggestSphere()
Dim partDocument As PartDocument
Set partDocument = CATIA.ActiveDocument
Dim part As Part
Set part = partDocument.Part
' Call function to find the biggest possible sphere
Dim center As Point, radius As Double
FindBiggestSphere part, center, radius
' Create the sphere
CreateSphere part, center, radius
End Sub
Sub FindBiggestSphere(part As Part, ByRef center As Point, ByRef radius As Double)
' Implement your algorithm to find the biggest possible sphere
' This may involve traversing the part's geometry and analyzing the dimensions
' For example, you can loop through all faces in the part to find the maximum
' distance between any two points. The center of the sphere will be the midpoint
' of the line connecting these two points, and the radius will be half of the distance.
Dim bodies As Bodies
Set bodies = part.Bodies
Dim hybridBody As Body
Set hybridBody = bodies.Item(1) ' Assuming the first body is the one containing your faces
Dim hybridShapes As HybridShapes
Set hybridShapes = hybridBody.HybridShapes
Dim maxDistance As Double
Dim face1 As HybridShapeFaceExplicit
Dim face2 As HybridShapeFaceExplicit
For Each face1 In hybridShapes
If TypeOf face1 Is HybridShapeFaceExplicit Then ' Check if it's a face
For Each face2 In hybridShapes
If TypeOf face2 Is HybridShapeFaceExplicit Then ' Check if it's a face
If face1 <> face2 Then
distance = CalculateDistance(face1.StartPoint, face2.EndPoint)
If distance > maxDistance Then
maxDistance = distance
center = CalculateMidPoint(face1.StartPoint, face2.EndPoint)
radius = distance / 2
End If
End If
End If
Next face2
End If
Next face1
End Sub
Sub CreateSphere(part As Part, center As Point, ByVal radius As Double)
Dim hybridShapeFactory As HybridShapeFactory
Set hybridShapeFactory = part.HybridShapeFactory
' Create the sphere
Dim sphere As HybridShapeSphere
Set sphere = hybridShapeFactory.AddNewSphere(center, radius)
' Update the part
part.Update
End Sub
Function CalculateDistance(p1 As Point, p2 As Point) As Double
Dim deltaX As Double
Dim deltaY As Double
Dim deltaZ As Double
deltaX = p1.X - p2.X
deltaY = p1.Y - p2.Y
deltaZ = p1.Z - p2.Z
CalculateDistance = Sqr(deltaX ^ 2 + deltaY ^ 2 + deltaZ ^ 2)
End Function
Function CalculateMidPoint(p1 As Point, p2 As Point) As Point
Dim midPoint As Point
midPoint.X = (p1.X + p2.X) / 2
midPoint.Y = (p1.Y + p2.Y) / 2
midPoint.Z = (p1.Z + p2.Z) / 2
Set CalculateMidPoint = midPoint
End FunctionBut this code keeps on giving me errors and i really dont know what to do,plus the fact that there is almost no information regarding macros for CATIA on the internet does not really help me in the slightest
