 History enabled

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 offset corner continuity handled. These options only apply if the offset direction is to the "outside" as shown in the image.


Original curve (blue). Offset to outside (red). Offset to inside (green).
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

Offsets 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.
