The Rib command extrudes a curve in two directions to a boundary surface.
Steps
- Select planar curves to rib.
- Select a boundary.
| Command-line options | |
|---|---|
| Offset | The offset direction relative to the input curve. InCurvePlaneUse when the input curve describes the rib in plan view. NormalToCurvePlaneUse when the rib curve describes the rib in elevation view. | 
| Distance | Sets the offset distance. | 
| Mode | StraightExtrudes the curve straight to the boundary. TaperedExtrudes the curves to the boundary with a draft angle. DraftAngleSpecify the draft angle for the taper. The draft angle depends on the construction plane orientation. When the surface is vertical/perpendicular to the construction plane, the draft angle is zero. When the surface is parallel to the construction plane, the draft angle is 90 degrees. |
