- The ElectricalFlattening.CATProduct is still open from the previous task.
- Set the default roll radius in the Flattening Parameters dialog box.
-
Select a point along the bundle segment you want to roll.
A green square and arrow appear identifying the point selected.
The branch end closest to the point of selection is taken as the reference point and is highlighted by a red square. The distance between this first roll point and the reference point is given in the dialog box (Position).
A dialog box also appears:
-
Optional, adjust the position of the roll point in the dialog box.
-
Optional, adjust the roll radius.
The default value in the dialog box is that specified via the default roll radius option in the Flattening Parameters dialog box. Note: The value entered can be less than the minimum bend radius.
-
Define the roll.
You can define the roll by specifying:-
The main direction.
You can select a line, an edge or another bundle segment as the roll direction. -
Or, an angle:
Either directly in the User value box,
Or,
By selecting two directions to retrieve the angle value.As above, you can select a line or an edge. Once the two directions have been defined, the angle between them is automatically calculated.
Note: By default, the roll plane is the active plane defined in the Flattening Parameters at the beginning of your session.

Click Apply. Entered values are applied but the dialog box remains open and you can still modify the inputs.
-
Click OK to validate.
The result looks like this. 
.
- Multi-profile bundle segments: in order to avoid twisted and impossible configurations, the local V-axis of the profile sketch is kept aligned with the normal direction of the active plane.
- Mechanical parts: a dashed green line visualizes the link between the bundle segment and mechanical part. Use the compass to reposition the part properly.
