Part Fillet/cs

The Part Fillet command creates fillets (rounds) on the selected edges of a shape. A dialog allows choosing which shape and which edges to work on.

Plate with filleted corners

1. Optionally select one or more edges in the 3D View.
2. There are several ways to invoke the command:
   • Press the Fillet button.
   • Select the Part → Fillet option from the menu.
3. The Fillet Edges task panel opens.
   • Optionally (re-) select an item in the Selected shape list in the Shape section or in the 3D View.
   • Edit the fillet parameters.
4. Press OK to close the task panel and apply the fillet.

Notes on application of Part Fillet

Part Fillet might do nothing if the result would touch or cross the next adjacent edge. Consequently, if you do not obtain the expected result, try with a smaller Radius value. This is the same for Part Chamfer.

The fillet command sometimes fails when trying to fillet complex shapes. A common cause of this may be that the shape being filleted is not geometrically correct. This may be the result of lines/planes etc not being removed after previous operations used to construct the shape ( e.g. Cut/Intersection/Fusion). A number of steps can be used to minimize problems:

• Where possible leave filleting a part until the part is completely generated. This will minimize interaction of fillets with subsequent Boolean operations;
• Use the Part → Check Geometry to check for any errors in the shape geometry and correct;
• Use Part → Copy → Refine Shape to remove any artifacts introduced by previous Boolean operations before filleting (and in some cases between filleting operations in sequence);
• Consider using Edit → Preferences → Part/Part Design to enable automatic checking and refining of the model after Boolean and sketch based operations (performance may be affected if these options are left switched on).
