To Create an Offset of a Curve on Surface

1. In the Model Tree, select the Style feature that contains the curve on surface (COS), and then right-click and choose

Edit Definition. The Style tab opens.

2. Click Style > Curve >

Offset Curve. The Offset Curve tab opens.

3. Click the

Curves collector, and then select one or more curves on surface (COS) to offset.

4. To set the distance to offset the curve, type a value in the Distance box, or drag the handle on the curve. Optionally, click

to export the parameter value to edit outside of Style.

Typing a negative value in the Distance box reverses the direction of the offset.

5. To offset the curve perpendicular to the reference plane, click

Normal.

6. To extend the start or end point of the curve to the nearest surface boundary, click the Options tab, and then select the Start or End check box.

If you select more than one curve, the start points or end points for all the curves extend to the nearest surface boundary.

7. Click

OK.
