# Ribbon ##

Ribbon The Ribbon command Offsets a curve and creates a ruled surface between the two curves. ### **Steps** 1. Select a curve. 2. Drag the cursor to one side of the curve and pick. ### Command-line options **Distance**: Sets the offset distance. **Loose**: The Corner and Tolerance options are not shown and do not affect the output. Polycurves are offset as a group of separate curve segments, and there is no corner trimming or filling. **Corner**: Specifies how corners are handled when they are offset to the "convex" side as pointed out in the image.

* Sharp: Curves offset to the outside of a corner will be extended to meet at sharp corners with position (G0) continuity.

* Round: Curves offset to the outside of a corner will be filled with arc segments with tangent (G1) continuity.

* Smooth: Curves offset to the outside of a corner will be filled with blend segments with curvature (G2) continuity.

* Chamfer: The corners of the offset curves will be filled with a straight line between their endpoints.

**ThroughPoint**: Offset through a picked point instead of at a distance. **Tolerance**: Sets the tolerance for the offset curve. Type 0 to use the default system tolerance. **BothSides**: Offsets the curve on both sides of the input curve. **InCPlane**: The curve is offset in the plane of the original curve. This option offsets the curve in the plane of the current construction plane instead. **OutputLayer** * Current: Place the results on the current layer. * Input: Place the results on the same layer as the input objects.
