More about Propagation Modes
Two propagation modes are available:
-
Minimal: Edges tangent to selected edges can be
taken into account to some extent. The app continues
filleting beyond the selected edge whenever it cannot do otherwise.
In the example below, the fillet is computed on the selected edge
and on a portion of tangent edges:

-
Tangency: Tangencies are taken into account to
fillet the entire edge and possible tangent edges.

Conic Parameter
Conic parameter under Options allows
you to vary the section of the fillet. For a parameter comprised between or equal
to:
- 0.5, the resulting
curve is a parabola.
- 0 < parameter < 0.5,
the resulting curve is an arc of an ellipse.
- 0.5 < parameter < 1,
the resulting curve is a hyperbola.
Notes:
- Conical
fillets do not handle twist configurations. If a twist is detected,
the fillet operation fails.
- Conical fillets may
produce internal sharp edges due to a curvature discontinuity of the
fillet supports. Healing is used to smooth these sharp edges.
- If the fillet surface
curvature is lower than the support curvature, fillet surface
trimming may fail. In such cases, the conic parameter has to be
decreased.
Additional Options
There are few more additional options available under Options:
Edges to keep:
When filleting an edge, the fillet
may sometimes affect other edges of the part, depending on the radius
value you specified. In this case, the app detects these edges
and stops the fillet to these edges.
Edge to be filleted:

The upper edge is not filleted:

A message appears asking if you
want to select the edge that you do not want to fillet.
- If you want to select the edge:
- Click Yes.
The Update Diagnosis dialog box appears.
- Click Edit.
- In the Edge Fillet.x dialog box, click in the Edges to
keep box and select the required edge in the
geometry.
The selected edge is highlighted indicating
that it will not be affected by the filleting
operation.
- If you do not want to select the edge, click No.
Limiting Elements:
Limiting element
lets you intersect the fillet with one or more planes. What you
need to do is either:
-
Select that plane or
-
Click one point located on the edge to be filleted.
After clicking, a blue disk appears indicating the limiting
element. The intersection with the fillet will then stopped at that
point.
An arrow appears on the plane to indicate the portion of
material that will be kept. Clicking this arrow reverses the direction
and therefore indicates that the portion of material that will be kept
will be the opposite one.
Blend Corners:
Sometimes, while filleting you can see that corners
resulting from the operation are not satisfactory, such as:

Blend Corners quickly
reshapes these corners . Clicking
Blend corners detects the corner to reshape and displays it
both in the box and in the 3D.

For each edge, enter a value in
the setback distance box. The setback distance determines for each edge
a free area measured from the vertex along the edge. In this area, the
system adds material to improve the corner shape. The result looks
like this:
