I though this would be a handy little macro to have, and good practise to make.

It's a macrofeature that deletes all solidbodies.

I've removed the Parents, so it can be reordered in the tree, and the parent features can be suppressed or deleted, but I couldn't work out how to just delete a Body - tout suite!

I realised I could perform a Cut Operation on the Body with a copy of itself, but surely I can just 'make' an empty body or whatever is required.

Function swmRebuild(swApp As SldWorks.SldWorks, swModel As SldWorks.ModelDoc2, swFeature As SldWorks.Feature) As Variant

   Dim swMFD As SldWorks.MacroFeatureData: Set swMFD = swFeature.GetDefinition
   Dim swPart As SldWorks.PartDoc: Set swPart = swModel
   swMFD.EnableMultiBodyConsume = True
   Dim swbtBodyType As swBodyType_e: swbtBodyType = swSolidBody
   Dim bVisibleOnly As Boolean: bVisibleOnly = False
   Dim vBodies As Variant: vBodies = swPart.GetBodies2(swbtBodyType, bVisibleOnly)
   Dim swBody As SldWorks.Body2
   If Not IsEmpty(vBodies) Then
      Dim i As Long

      For i = 0 To UBound(vBodies)
         Set swBody = vBodies(i)
         Dim swbOperationType As swBodyOperationType_e
         swbOperationType = SWBODYCUT
         Dim swboErrorCode As swBodyOperationError_e
         swBody.Operations2 swbOperationType, swBody.Copy, swboErrorCode
      Next i
End If
swMFD.EditBodies = vBodies

Dim ParentFeatures(0) As SldWorks.Feature
Set ParentFeatures(0) = swPart.FeatureByName("Solid Bodies")
swMFD.Parents = ParentFeatures

Set swmRebuild = swBody

End Function
