* 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. |

Description
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).
Usage
- Select one or more objects.
- Select the Part → Create a copy → Refine shape option from the menu.
- For each object a cleaned, parametric copy is created
- 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()
