Part RefineShape

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



Use

 * 1) Select the shape to be cleaned.
 * 2) Use the menu.
 * A copy of the object is created and totally cleaned, the original object is rendered hidden.
 * The newly created copy is independent of the original. In FreeCAD 0.19 the RefineShape feature defaults to a parametric (linked) copy. This behavior can be changed with ParametricRefine parameter described in Fine-tuning.

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 preceding shapes are changed.

Scripting
The Python command for refining a shape is the following:
