    Cleans unnecessary lines. After a Boolean operation, some lines defining the previous form remain visible, this tool creates a copy of the totally cleaned.

    1. Select the shape to be cleaned.
    2. Click the OpenSCAD → Refine shape menu.
    • A parent-object is created and totally cleaned, the original object is rendered hidden.


    • The refinement algorithm only works on shells. Therefore it iterates over the shells of the input shape and then for each shell it creates a new shell with joined faces wherever possible. This means if your input shape is only a face, wire, edge or vertex then the algorithm does nothing.
    • As opposed to Part RefineShape.svg Part RefineShape in the Workbench Part.svg Part Workbench, this feature WILL update when the underlying shapes are changed.


    • the function does not modify the existing shape, but returns a new shape.
    • the function is normally used as last step in the modelling history.
    • the function can help to get difficult fillets to work.
    • the function is intended to stop 3D printers from printing unwanted edges.
