The OffsetMultiple command copies multiple curves so that all locations on the copied curves are a specified distance from the original curve.
Note
- All open curves offset toward the cursor.
- When offsetting closed curves, if the side-to-offset point is inside a curve, the offsets for other closed curves will also be inside.
- Islands (closed curves inside other closed curves) are recognized and offset in the opposite direction from the container closed curves.
Steps
- Select curves and edges.
- Click on to specify the side.
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.
- Polycurve segments offset individually. Segments will break apart at corners in the result.
- The Corner and Tolerance options are not used and are not shown.
- Curves with fewer edit points may distort more in the result.
-
The output curve has the same parameter structure as the input curve.
No - Offsets the curve shape within the Tolerance setting.
- A small tolerance creates an output curve with more control points.
Corner
Specifies how corners are handled when they are offset to the "convex" side as pointed out in the image.
Original curve (blue). Offset curve (red).
Sharp
Extend the adjacent offset segments to form a sharp corner.
Round
Fill the gap between adjacent offset segments with a tangent arc segment.
Smooth
Fill the gap between adjacent offset segments with a degree 3 tangent segment.
Chamfer
Fill the gap between adjacent offset segments with a straight segment.
None
Leave the gap open between adjacent offset segments.
Trim
Specifies whether the intersected curve segments will be trimmed to the corners. No creates self-intersected curves.

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.
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.
OffsetCount
Specifies the number of curves that will be created.
