Description

This SOLIDWORKS macro provides a fast and efficient way to export active documents to the IGES file format (.igs). Designed for SOLIDWORKS parts and assemblies, this macro automatically saves the exported IGES file to the same directory as the original document, using the same filename. With the ability to export part and assembly to IGES file, this is an ideal solution for you if you are someone who frequently needs to save their CAD files in a universal format for compatibility with other CAD software.

Sub main()

    Set swApp = Application.SldWorks

    ' Exit if no document is active
    If Part Is Nothing Then Exit Sub
    
    ' Get the path of the active document
    Dim Path As String
    Path = Part.GetPathName
    
    ' Exit if the active document is a drawing (since IGES export is not supported for drawings)
    If Part.GetType = swDocDRAWING Then
        Exit Sub
    End If
    
    ' Prepare the path for the IGES file by replacing the extension
    Dim Extension As String
    Extension = Mid(Path, InStrRev(Path, "."))
    Path = Replace(Path, Extension, ".igs")
    Extension = ".igs"

    ' Export the file as IGES
    longstatus = Part.SaveAs3(Path, 0, 0)

    ' Notify the user about the saved file location
    MsgBox "Saved " & Path, vbInformation
End Sub
