Hi,

The Macro below saves the selected body (of a part) into a STL file.

I have been using it in SW2017 on a daily basis, but after upgrading to SW2018 it stopped working...

It now saves an empty STL file of 1 kB. Does anybody know what goes wrong?

Option Explicit

Sub main()

Dim swApp As SldWorks.SldWorks

Dim swModel As SldWorks.ModelDoc2

Dim swSelMgr As SldWorks.SelectionMgr

Dim swBody As SldWorks.Body2

Set swApp = Application.SldWorks

Set swModel = swApp.ActiveDoc

Set swSelMgr = swModel.SelectionManager

Set swBody = swSelMgr.GetSelectedObject6(1, -1)

Dim FilePath As String

Dim NewFilePath As String

Dim ConfigName As String

Dim BodyName As String

'Save the active model

swModel.Save3 0, 0, 0

'Check if the the active model is a PART  and if there is a solid body selected

If swModel.GetType = swDocPART Then

    If swBody Is Nothing Then

        MsgBox "Please select a solid Body"

    Else

        FilePath = swModel.GetPathName

        ConfigName = swApp.GetActiveConfigurationName(FilePath)

        BodyName = swBody.Name

        NewFilePath = Left(FilePath, InStrRev(FilePath, "\")) & ConfigName & " [" & BodyName & "]" & ".STL"

        swModel.SaveAs2 NewFilePath, 0, True, False

        MsgBox "van Cronenburg 3D Print STL saved." & vbNewLine & vbNewLine &  "Filename: " & ConfigName & " [" & BodyName & "]." & "STL"

    End If

End If

End Sub

Kind regards,

Thomas
