Описание

The PartDesign Fillet tool creates fillets (rounds) on the selected edges of an object. It adds a Fillet object to the document with its corresponding representation in the Tree view.

Применение

Добавление скругления

  1. Optionally activate the Body to fillet.
  2. There are several ways to select edges to fillet:
    • Select one or more edges of the Body individually.
    • Select one or more faces of the Body to select all their edges.
    • Select a feature (usually the last feature) of the Body to select all its edges.
  3. For a chain of tangentially connected edges only a single edge needs to be selected, the fillet will propagate along the chain.
  4. There are several ways to invoke the tool:
    • Press the Fillet button.
    • Select the Part Design → Apply a dress-up feature → Fillet option from the menu.
  5. If there is no active Body, and there are two or more Bodies in the document, the Active Body Required dialog will open and prompt you to activate one. If there is a single Body it will be activated automatically.
  6. The Fillet parameters task panel opens. See Options for more information.
  7. Press the OK button to finish.

Редактирование скругления

  1. Do one of the following:
    • Double-click the Fillet object in the Tree view
    • Right-click the Fillet object in the Tree view and select Edit Fillet from the context menu.
  2. The Fillet parameters task panel opens.See Options for more information.
  3. Press the OK button to finish.

A PartDesign Fillet object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

Известные проблемы

Fillets, chamfers, and other features that operate on solid bodies depend on the underlying OpenCASCADE Technology (OCCT) kernel that FreeCAD uses. The OCCT kernel occasionally has difficulty handling coincident sharp edges, where two faces meet. If this is the case FreeCAD may crash without an explanation.

If run from the terminal, FreeCAD may output a log like this after a crash: 

#1  0x7fff63d660ba in BRep_Tool::Curve(TopoDS_Edge const&, TopLoc_Location&, double&, double&) from /usr/lib/x86_64-linux-gnu/libTKBRep.so.7+0x2a

#8  0x7fff723be48e in PartDesign::Chamfer::execute() from /usr/lib/freecad-daily/lib/_PartDesign.so+0x60e
...

This output references functions from OCCT libraries. If this type of crash occurs, the problem may need to be reported and solved in OCCT rather than in FreeCAD.

Topological naming

Edge numbers are not completely stable, therefore it is advisable that you finish the main design work of your solid body before applying features like fillets and chamfers, otherwise edges could change names and filleted edges would likely become invalid. When the ДанныеUse All Edges property is true there is some protection from this. Because in such cases all the edges of the base object are used and there is no dependence on individual edge names.
