Fillet
Round the corners of 2D sketch curves to create fillets with the same radius or different radii.
- 
                Click the Fillet icon. 
 
- 
                Select the corners to fillet. You can only select a corner between two straight
                    lines.
                - To select a corner, click the vertex.
- To select multiple corners, use box selection (click-and-drag the mouse).
 Previews of the fillets are displayed. A tangent constraint is automatically applied to the fillets.
- 
                Define the radius, enter a value in the microdialog and press
                        Enter.
                Tip: If the radius is too large, the fillet preview is displayed in red. Decrease the radius to create a valid fillet. 
- To apply the same radius to all fillets, select the Uniform Radius = button on the microdialog.
- 
                Right-click and mouse through the check mark to exit, or
                    double-right-click.
                The fillets are created with the dimensions of the radii indicated.Tip: To see which fillets have the same radius, hover over an equal sign. Fillets with the same radius are highlighted in yellow.
