Offset Curve

 History enabled

The Offset command copies a curve so that all locations on the copied curve are a specified distance from the original curve.

Steps

  1. Select a curve or edge.
  2. Click on one side the curve.
    For best results, use proportionately small offset distances and smooth curves; otherwise, you may get kinks and doubled-back curves.

Command-line options

Distance

Sets the offset distance.

Loose
Yes

Offsets a curve by moving its edit points.

 

No

Offsets the curve shape within the Tolerance setting.

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.

Cap

Closes the gap at the curve ends.

None

No closing segments are added. The offset curve goes on the current layer.

Flat

Straight-line segments are added between the curves and joined. The object goes the same layer as the original.

Round

Tangent arcs are added between the curves and joined. The object goes the same layer as the original.

SubCrv

Type subcrv to select part of a curve as input.

OffsetMesh

Copy a mesh parallel to the original.

OffsetCrvOnSrf

Copy a curve on a surface parallel to the original.

OffsetNormal

Copy a curve on a surface parallel to the original in the surface normal direction.

OffsetMultiple

Copy curves or surface edges parallel to the original.
