-
Select the joint body in the specification tree.
-
Click BiW Welding CurveBead
in the Welding toolbar.
The BiW CurveBead Fastener Definition dialog box opens. |
-
Specify whether you wish to use the existing standard or
not.
If a standard has been
imported, a curve bead is created using this standard. If not, you
are able to define your own values for each attribute. |
 |
|
 |
If the
last location method is different from Explicit, the ABF
application creates a specification part associated to the assembly
joint if this specification part does not already exist. |
 |
You must not delete this
specification part. |
-
Select the process type and the
stacking.
-
Define the functional parameters
of the curve bead:
|
 |
-
Discretization Method:
-
Unspecified: no discretization method is used. The default
visualization is set in Tools > Options > General >
Display > Performances > 3D Accuracy.
-
Sag:
segments are defined on the curve according to the
tolerance value set in the discretization parameter.
-
Step: equidistant points are created on the curve
according to the value set in the discretization parameter.
-
Discretization Parameter: distance value for each curve bead
depending on the chosen discretization method.
|
Both parameters will be used for the visualization of the curve
bead and for the export/report. |
-
Specify the material.
-
Specify the definition:
-
curve path
-
cylinder
path
-
half
cylinder path, etc.
|
-
Define the diameter in the following cases:
- Curve Path
- Cylinder Pipe
- Half Cylinder Pipe
|
 |
Curve Path |
|
 |
Cylinder |
|
 |
Half Cylinder |
-
Define the base and height in the following cases:
- Diamond Pipe
- Half Diamond Pipe
- Rectangle Pipe
- Half Rectangle Pipe
|
 |
Diamond Pipe |
|
 |
Half Diamond Pipe |
|
 |
Rectangle Pipe |
|
 |
Half Rectangle Pipe |
-
Select the location (see
below):
|
According to the location you choose, different dialog boxes
open, except when selecting the Explicit mode. |
-
Define the orientation of the
curve bead by setting the K axis to either:
|
 |
|
 |
To visualize the K axis, the
K Axis Only option should be checked in Tools > Options. |
-
Click OK to create the curve bead.
The curve bead (identified as Joint Element.xxx) is added to the
specification tree, under the Assembly Joint Body node. |
 |
|
Locating the CurveBead
|
Along Curve
|
-
Select the
curve.
Green arrows appear in the 3D geometry to let you know the
end and start point of the curve bead: |
 |
-
Click the
More>> button to display further information.
-
From the
Along Curve Location dialog box, click the Swap Start and End
Points button to change the curve direction.
 |
|
 |
The Split Support Curve
enables to trim the curve bead. |
The curvebead will be created along the original
curve. |
 |
|
From Curve On Surface
|
-
Select a curve, for instance a part edge.
Most of
the times, a surface is selected by default. |
Green arrows appear in the 3D geometry to let you know the
end and start point of the curve bead. |
-
If needed,
select a surface.
 |
If the surface could not be found, or if you want to select
another surface, choose a surface in the drop-down list. To
choose an unspecified zone, select Other (Zone Unspec)
and then select the zone in the 3D geometry. |
-
Optionally
modify the offset. In our example, we defined an offset of 10mm.
-
Click the
Swap Start and End Points button to change the curve
direction.
-
Click the
Inverse Offset button changes the offset curve bead
position according to the original curve bead.

|
 |
The Split Support Curve
enables to trim the curve bead. |
|
The curve bead will be created along the original
curve offset. |
 |
If several solutions are possible (for instance
if there is a hole on the surfaces), you need to select the
surface in the 3D geometry that is the closest to the curve bead
to be created: |
 |
 |
|
Intersect
|
Open the
Intersect1.CATProduct document. |
- Click the More>> button to display further
information.
- Successively select two surfaces, either in the 3D geometry or in
the specification tree.
The curve bead is located at the intersection of
the two surfaces. |
 |
 |
|
- Click the Swap Start and End Points button to change
the curve direction.
 |
The Split Support
Curve enables to trim the curve bead. |
The curve bead will be created from the
intersection of the two surfaces. Its normal is the normal to the
first selected surface at the curve bead's start point. |
 |
If several solutions are possible (for instance
if there is a hole between the two surfaces), you need to select
the surface in the 3D geometry that is the closest to the curve
bead to be created: |
 |
 |
|
Explicit
|
- You need to select first one of the three other options (Along
curve, from curve on surface, or Intersect) to be able to select the
curve position.
- When selecting the Explicit mode, the curve location is kept and
it cannot be modified.
The curve location is then a polyline, which is recalculated
according to the selected curve, and does not reference the
specification part anymore.
 |
When the location method
switches to Explicit, the
specification part is automatically deleted if it is empty. |
- The polyline is computed according to the discretization
parameters. If it is set to Unspecified, the discretization value is
calculated from the options defined in Tools > Options >
General > Display > Performances > 3D Accuracy.
- The Isolate command has the same behavior as the
Explicit method: you can select the Isolate item from the
contextual menu once the curve is created, by right-clicking the
joint element.
