Description

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

Usage

1. Select the shape to be cleaned.
2. Select the OpenSCAD → Refine Shape Feature option from the menu.
3. A parent-object is created and totally cleaned, the original object is rendered hidden.

Limitations

• 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.

Notes

• 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.
