Part RefineShape

Description
Part RefineShape produces a non-parametric copy with a refined shape, that is, with certain edges and faces cleaned up.

After certain boolean operations, like Part Union, some lines from the previous shapes main remain visible. This tool produces a copy of that boolean result, and cleans up those seams.

To produce other non-parametric copies use SimpleCopy, TransformedCopy, and ElementCopy.



How to use

 * 1) Select an object that you wish to clean and copy.
 * 2) Go to the menu.
 * 3) A cleaned, independent copy of the original object is created; the original object is hidden.

Starting in FreeCAD 0.19, the result defaults to a parametric (linked) copy.

This behavior can be changed in the parameter editor. Go to the subgroup

and change of type  to  to get the old behavior (independent copy).

See other parameters 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 that if your input shape is only a face, wire, edge or vertex then the algorithm does nothing.
 * Unlike the OpenSCAD RefineShapeFeature command, Part RefineShape won't update when the preceding shapes are changed.

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