Creating Spline Offsets

This task shows you how to create an associative offset based on an existing spline.

Create a spline.

Select the Offset command from the Transformation sub-toolbar in the Operation toolbar

Click the spline.
Click in the geometry area to create the offset.

The offset is created as long as a new feature OffsetCurve which is visible in the specification tree.

Note that:

The visualization of the offset implies an automatic creation of elements, which are automatically put in no show and construction mode.
These elements are put in no show mode only if the Geometrical Constraint option in the Sketch tools toolbar is activated.
These elements are also deleted if the offset or the original spline are deleted.
The created offset will be associative with the original spline only if the Dimensional Constraint option in the Sketch tools toolbar is activated, see Editing Spline Offset.

When creating an offset of a spline, a constraint is automatically created and the offset cannot be deleted.
Both the spline and the constraint can be edited.

Inconsistent Spline Offsets

If the reference spline is deleted, the spline offset becomes inconsistent (the spline offset color turns red). As a result, when you exit the Sketcher workbench the Update Diagnosis dialog box is displayed and an error message appears within the dialog box. Just double-click the spline offset to re-edit it.
