Autodesk 3ds Max MAXScript: Save Scene as Multiple Formats (.3ds, .max, .ABC, .STL, .DWG, .obj, .fbx)

This MAXScript code displays a save file dialog box, enabling users to save their 3ds Max scene in multiple formats: .3ds, .max, .ABC, .STL, .DWG, .obj, and .fbx.

-- Display the save file dialog box
fileName = getSaveFileName caption:'Save As' types:'3DS (*.3ds)|*.3ds|MAX (*.max)|*.max|Alembic (*.ABC)|*.ABC|STL (*.STL)|*.STL|DWG (*.DWG)|*.DWG|OBJ (*.obj)|*.obj|FBX (*.fbx)|*.fbx|'

-- Check if the user clicked the 'Cancel' button
if fileName == undefined do
(
    print 'User canceled the save operation.'
)

-- Otherwise, save the scene as the selected file format
else
(
    -- Get the file extension from the selected file name
ext = getFilenameType fileName

    -- Save the scene as the selected file format
    case ext of
    (
        '.3ds': exportFile fileName #noPrompt using: #exportSelected
        '.max': saveMaxFile fileName
        '.ABC': exportFile fileName selectedOnly:true asSingle:true using: #Alembic
        '.STL': exportFile fileName #noPrompt using: #exportSelected
        '.DWG': exportFile fileName #noPrompt using: #DWG
        '.obj': exportFile fileName #noPrompt using: #exportSelected
        '.fbx': exportFile fileName #noPrompt using: #FBX
        default: print 'Unsupported file format.'
    )
)

This script utilizes the getSaveFileName function to display a dialog box where users can choose a filename and format. The types parameter lists the available file formats. After selecting a filename and format, the script uses a case statement to determine the appropriate export function based on the file extension. Each export function is called with the selected filename and necessary options, such as #exportSelected for exporting only the selected objects. If the selected file format is unsupported, a message is printed to the MAXScript listener.
