Rounding the Edge of Objects (Fillet Command)

The fillet command rounds the object at the original edges and vertices. The edges and vertices are replaced by new rounded surfaces that are tangential to the original adjacent surfaces, providing a smooth transition.

Vertices are only going to be replaced by new rounded surfaces if all the edges connecting to the original vertex are selected; otherwise, the vertex is preserved but moved (if necessary). The edges are replaced by quarter-cylindrical surfaces, of which the radius can be customized (see the Fillet Radius property). Vertices are replaced by more complicated new faces. You can control the setback distance.

The fillet command is disabled if an edge is not selected.

To switch to edge selection mode:

• Right-click the desktop, and choose Select Edges from the shortcut menu.

To round the edge of an object:

1. Select the edge you want to change.

   The edge is highlighted and the Fillet command is enabled.

2. From the menu bar, click Modeler> Fillet or, on the Draw ribbon tab, click the Fillet icon:

   

   The Fillet Properties dialog box is displayed:

   

3. Enter a value for the Fillet Radius and select units from the drop-down menu.
4. Enter a value for the Setback distance.

   The setback distance controls the shape of the vertex. It is the distance of the cross curve from the vertex at the end of the edge. If it is less than the fillet radius the Setback distance has no effect. Also, you will get an error if it is greater then the length of the edge. Note that the setback feature only works on corners where three or more edges meet and only if all edges meeting at the vertex are selected.

5. Click OK to apply the change to the edge.

   The dialog box closes and the object edges and vertices are rounded as specified.
