Sketch Fillet

1. Click or press Shift+f.
2. Select a point or two sketch curves.

   

3. The radius dialog opens, click in the dialog and enter the radius.

Line, make selections

1. Click first line; no highlighting occurs.
2. Click and drag second line to estimate size of fillet.
3. Enter value for fillet radius and press Enter.

Vertex, make selections

1. Click .
2. Click a vertex.
3. Enter the radius value and press Enter.
4. Each subsequent click with the Fillet tool selected results in equal-sized fillets.
   
   

Spline, make selections

1. Click the .
2. Click the left spline near the top (not the point).
3. Click the right spline near the top (not the point).
4. Enter the fillet radius value and press Enter.
   
   
   
   

You may notice a small, open circle after the fillet is applied, where the lines used to meet. This is a virtual sharp that is added to the sketch as reference geometry. This virtual sharp will retain the coincident constraints on the two lines, as well as a dimension (radius of the fillet). You may want to use this as a reference point for adding constraints, for example. You may also choose to simply ignore it. (See the "Vertex, make selections" example above to see the virtual sharp.)

• To apply more than one fillet of the same size, make the first selection, enter the radius, then click the other points to fillet. The first value entered becomes the default and that size fillet will be applied to all selected points. You are able to change the first value to change all values.

  

  If the default fillet size is too large for a selected point, the fillet line is displayed in red.

  

  You are able to drag the manipulator to resize the fillet.

  

  You are also able to click to activate the value and enter a new value for the fillet size:
