Fillet

Menu access: Shape | Fillet

Description:

Allows you to create a constant radius fillet on edges of a shape (surface or solid).

General philosophy:

1. Enter the fillet radius.

2. Select one or several edges or faces.

3. Start the fillet computation by using the  COMPUTE FILLET(S)  button.

Available option(s):

The drop-down list gives you the choice between several type of fillets:

• ONE RADIUS : all the fillets created have the same radius. If you change the radius value in the corresponding cell while selecting edges, all the fillets on the edges already selected will also use this new value.

In this mode, the button  SHAPE  allows you to apply a fillet with same radius to all the edges of a shape.

• SEVERAL RADIUS : you can create several fillets with different radius at one. If you modify the radius value in the corresponding cell while selecting edges, all the fillets on the edges already selected will keep their own value.

• VARIABLE FILLET : allows you to access to the variable fillet function.

• FILLET BETWEEN FACES : allows you to access to the fillet between faces function.

• 3 FACES FILLET : allows you to create "U shaped" fillet between 3 faces.

The option  Follow tangent edges= YES  or  NO  allow you to make an automatic propagation of the selection along all the tangent edges.

The  CORNER  button allows to define the size of the corner blend fillet (the blend surface between the three edges) that meet on a corner. All the edges of this corner must be selected.

The  >>  button allows you to set (using a dialog box) the way the fillets are trimmed if they overflow the neighbouring faces.

Specific point(s):

When selecting edges, preview of the result is displayed. You can set the color of this preview or deactivate it through the menu "Tools | Options" rubric "Shape".

The shape of the fillet changes according to the selected edges and the order of their selection.

You can select again an already selected edge to remove it from the selection list.

When you select a face, all the outside edges of the face are selected to create the fillet.

 When you have different fillets coming on to the same vertex, it is better to create them in decreasing radius values.

 In case of error, you can try to:

•  Decrease the fillet values, on one or several edges,

•  To create fillets on adjacent edges.

Limitation(s):

 It is impossible to create a fillet on an edge between two tangent faces.

 It is impossible to create a fillet on an edge arriving on a singular point.

In this case, you must use a variable fillet.

Available modification(s):

By using the "modify" function, you can modify the radius value, suppress some fillets or add new edges.
