To Offset a Curve Along a Surface
1. Select a curve and click > . The surface is highlighted, and the Offset tab opens. The selected curve appears in the Offset curve collector on the References tab.
2. Select
![](../../../../../simulate/simulate/images/offset_curve_along_surface.png)
to offset the curve in the direction along the reference surface.
3. Select a quilt or surface to act as a reference for the offset curve. By default, the quilt or surface on which the offset curve is located is selected as the reference.
4. Type an offset value in the
![](../../../../../simulate/simulate/images/value.png)
box.
5. Click
![](../../../../../simulate/simulate/images/dash_flip_16.png)
to flip the direction of the offset, if necessary.
6. In the
Measurements panel, specify the measurement type as either
![](../../../../../simulate/simulate/images/measure_normal_to_curve.png)
(normal to curve) or
![](../../../../../simulate/simulate/images/measure_parallel_to_plane.png)
(parallel to plane). If you select
![](../../../../../simulate/simulate/images/measure_parallel_to_plane.png)
, select a reference plane.
7. Click

.
| If you are using a chain as a reference and you want to modify it, click Details on the References tab and use the Chain dialog box. |
