You can define the following options:
- Curve 1, Curve 2: Select the curves between which the fillet curve shall be created. If the check button for
Curve 2 is switched off, you can also select a single curve for the styling corner creation to obtain a closed fillet
curve.
Trim Curve 1/2: Switching on Trim will trim the corresponding
input curve 1 or 2 selected to the arc end point of the styling curve being generated.
When trim is on, the original input curve is placed in no-show.
- Radius: The accumulating points of the fillet curve into the original curves are defined by specifying an arc
radius value.
|
|
- Curve Type: Definition of the fillet type.
Arc: The fillet curve will be an arc with a defined Radius,
the arc radius. The arc radius determines the position of the accumulating points of the fillet curve. If the curve tangent vectors of the original curves at the ends of the arc are located in the same plane, tangent
continuous transitions are realized.

Blend: The fillet curve is calculated from the radius and the continuity
specified.
Shape Blend: The fillet curve is calculated from the radius
and the continuity specified. In addition, the shape can be influenced with the options Center
Radius and Form Factor.

|
- Projection - Support: The fillet curve can be projected onto a surface or a plane to be selected.
|
|
- Curve 1/2 Options:
Only available for the Curve Types Blend and Shape Blend.
- Continuity:
: The created fillet curve will be G0 (position) continuous.
(Lead-in Tangent): An accumulating arc with tangent continuous transition to the original curves will be created.
The accumulating points are also defined by the arc radius. In addition, for the middle of the arc you can specify a
Center Radius different from the arc radius. The transition quality will be preserved when changing
the center radius.
-
(Lead-in Curvature): The created fillet curve will be an accumulating arc with
curvature continuous transition to the original curves. The curvature radius at the accumulating points will be adopted
from the original curves. In addition to the arc and center radius you can specify the Lead-in Radius
at the accumulating points. However, in this case the transition quality will not be preserved.
: The created fillet curve will be G3 (torsion) continuous).
- Lead-in Radius: For an accumulating arc with curvature continuous transition to the original curves at
the accumulating points (option Acc Curvature) the accumulating radius can be modified. In this case, the
curvature continuity will not be preserved.

- Shape: Definition of the fillet shape:
- Center Radius: In case of an accumulating arc with tangent or curvature continuous
transition to the original curves at the accumulating points (options Acc Tangent and Acc Curvature)
the radius in the middle of the fillet curve can be specified. The transition quality will be preserved.
- Form Factor: If accumulating arcs have been created using Acc Tangent and Acc Curvature
the tangent length of the fillet curves is modified. The transitions to the original curves remain unchanged. Values
smaller than 1 create flat fillets, values higher than 1 steep fillet.
