The {{Button|[[Image:Part_RefineShape.svg|16px]] [[Part_RefineShape|Part RefineShape]]}} produces a non-parametric copy with a refined shape, that is, with certain edges and faces cleaned up.
The [[Image:Part_RefineShape.svg|24px]] '''Part RefineShape''' command produces parametric copies with a refined shape from selected objects. It can for example be used to remove unnecessary edges left over after a [[Part_Fuse|Part Fuse]] operation.

After certain boolean operations, like [[Part_Fuse|Part Fuse]], some lines from the previous shapes may remain visible. This tool produces a copy of that boolean result, and cleans up those seams.

'''Alternatively''', to produce other non-parametric copies use {{Button|[[Image:Part_SimpleCopy.svg|16px]] [[Part SimpleCopy|Simple Copy]]}}, {{Button|[[Image:Part_TransformedCopy.svg|16px]][[Part TransformedCopy|Transformed Copy]]}}, and {{Button|[[Image:Part_ElementCopy.svg|16px]] [[Part ElementCopy|Element Copy]]}}

# Select an object that you wish to clean and copy.
# Select one or more objects.
# Go to the menu {{MenuCommand|Part → Create a copy → [[Image:Part_RefineShape.svg|16px]] Refine shape}}.
# Select the {{MenuCommand|Part → Create a copy → [[Image:Part_RefineShape.svg|16px]] Refine shape}} option from the menu.
# A cleaned, independent copy of the original object is created; the original object is hidden.

# The original objects are hidden.

As of {{VersionPlus|0.19}} the result defaults to a parametric (linked) copy.

This behavior can be changed in the [[Image:Std_DlgParameter.svg|24px|link=Std DlgParameter]] [[Std DlgParameter|Parameter editor]]:
# Go to the subgroup: {{incode|BaseApp/Preferences/Mod/Part}}
# Change {{incode|ParametricRefine}} of type {{incode|Boolean}} to {{FALSE}} to get the old behavior (independent copy).

See other parameters in [[Fine-tuning|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 [[Image:OpenSCAD_RefineShapeFeature.svg|24px]] [[OpenSCAD RefineShapeFeature|OpenSCAD RefineShapeFeature]] command, [[Image:Part_RefineShape.svg|24px]] [[Part_RefineShape|Part RefineShape]] won't update when the preceding shapes are changed.

Popis

Vyčistí zbytečné čáry. Po logických operacích zůstávají viditelné čáry, které definovaly původní tvary. Nástroj vytváří kopii vyčištěného objektu.

The Part RefineShape command produces parametric copies with a refined shape from selected objects. It can for example be used to remove unnecessary edges left over after a Part Fuse operation.

Original with 11 faces (left), and refined copy with 7 faces (right).

Použití

  1. Vyberte tvar, který má být vyčištěn.
  2. Klikněte na menu Díl → Vyčistit tvar.
  • Je vytvořena kopie objektu a je kompletně vyčištěna, původní objekt je skryt.
  • Nově vytvořená kopie je nezávislá na originálu.
  1. Select one or more objects.
  2. Select the Part → Create a copy → Refine shape option from the menu.
  3. For each object a cleaned, parametric copy is created
  4. The original objects are hidden.

Notes

  • This command can be used as the last step in a traditional constructive solid geometry workflow.
  • It may help to clean up the model before applying other features, such as fillets.
  • Cleaning up an object may prevent 3D printers from printing unwanted edges once the object is exported to a mesh format.
  • This command can also be used after converting a mesh to a shape (Part ShapeFromMesh).
  • By default this command creates parametric (linked) copies. There is fine-tuning parameter to change this to non-parametric copies. More information about parametric/non-parametric copy behavior can be found in this forum post.
  • Some interesting information about what is happening with placement and how to access by Python can be found in this forum post.

Scripting

The Python command for refining a shape is the following:

shape.removeSplitter()
