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.

Use

  1. Select the shape to be cleaned.
  2. Click the Part → Refine shape menu.
  • A copy of the object is created and totally cleaned, the original object is rendered hiden.
  • The newly created copy is independent of the original.

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.
  • Opposed to RefineShapeFeature in OpenSCAD workbench, this feature won't update when the underlying shapes are changed

Scripting

The Phyton command for refining a shape is the following:

shape.removeSplitter()

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
