|Part → Fillet|
|Introduced in version|
This tool creates fillets (rounds) on the selected edges of a shape. A dialog allows choosing which shape and which edges to work on.
- Invoke the tool from the Part toolbar or from the Part → Fillet menu. You can select the shape before invoking the tool.
- If the shape was not selected prior to invoking the tool, select it in the Shape drop down list in the Task Panel.
- Select the fillet type, either constant radius (default) or variable radius.
- Select the edges either in the 3D view, or by ticking them in the edge list in Task Panel.
- Set the radius value.
- Click to validate.

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 tool 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 → 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 → PartDesign 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).
The fillet tool is affected by the topological naming problem when making a change to a modeling step earlier in the chain that affects the number of faces or vertices. This could cause unpredictable results. Until this problem is resolved it is advised to apply chamfer and fillet operations as the last steps in the modelling chain.
