Opens a local 3D model file from disk.

1. Click File > Open > Open File.
2. In the file browser dialog, select one or more model files.
3. The model loads into the viewport. If a model is already open, it will be closed first.

• Supported formats include SVLX (native), as well as CAD formats such as DWG, DXF, SLDPRT, SLDASM, CATPART, CATPRODUCT, and others. CAD files are automatically converted on import.
• Multiple files can be selected and opened simultaneously.

Opens a built-in sample model file included with the application.

1. Click File > Open > Open Sample.
2. Select a sample model from the dialog.
3. The sample loads into the viewport.

Creates a new empty 3D workspace.

1. Click  File > Open > Create.
2. A new blank 3D document is created. If a model is already open, it is closed first.
3. The default workspace panels (Model, View, Animation, etc.) are displayed.

• The new document is local and unsaved until explicitly saved.

Displays a list of recently opened model files in the right panel of the **File > Open** menu. Each entry shows tthe file name and an
icon indicating whether it is a 2D or 3D model.

1. Click File.The recent documents listcappears on the right side of the menu.
2. Click a file name in the list to open it directlLy.

• Up to 10 recently opened files are retained.
• The list is updated automatically when a file is opened or saved.

2. Save

Saves the current file, overwriting the existing file on disk. Shortcut: Ctrl+S.

Operation:

1. Click File > Save or press Ctrl+S.
2. If the file has not been saved before, a Save As dialog opens to choose a location.
3. All modifications — including annotations, measurements, animations, section planes, materials, and model data — are saved.

Notes:

• If multiple files are open simultaneously, save is not supported; a warning is shown.

3. Save As

Saves the current file to a new location or with a new filename.

Operation:

1. Click File > Save As.
2. In the Save As dialog, choose a destination folder and enter a filename.
3. Click Save to write the file.

4. Export

Opens the export submenu. Currently one export option is available:

Exports the current viewport as an SVG vector image file.

Operation:

1. Click File > Export > Export SVG.
2. The view automatically switches to orthographic projection.
3. Configure the paper size and orientation in the export dialog (settings are shared with the SVG Export settings in Preferences).
4. Click Export. A progress dialog appears while the file is being generated.
5. The SVG file is saved to the selected path. The view returns to its previous projection when export completes.
