Offset an Object
For example, if you offset a circle or an arc, a larger or smaller circle or arc is created, depending on which side you specify for the offset. If you offset a polyline, the result is a polyline that parallels the original.
- Ellipses and elliptical arcs (resulting in an oval-shaped spline)
- 2D polylines
- Construction lines (xlines) and rays
The command creates a closed polyline or a spline from the edges of a planar face on a 3D solid or surface. Splines result when one or more edge segments cannot be represented as lines, arcs, or a circle. For example
- In the left illustration, the edge of the top surface of the solid was offset, resulting in the closed, yellow polyline shown.
- In the middle illustration, the polyline was extruded.
- In the right illustration, the polyline was extruded and then subtracted.
With the Corner option, you can specify sharp corners or rounded corners for the polyline. External and internal corners create rounded corners differently depending whether the corners are concave or convex—the radius of the arcs maintain the specified offset distance.
- Home tabModify panelOffsetAt the Command prompt, enter offset.
- Specify the offset distance.
- Select the object to offset.
- Specify a point to indicate whether the object is to be offset inside or outside of the original object.
- Select another object to offset, or press Enter to end the command.
- Solid tabSolid Editing panelOffset EdgeAt the Command prompt, enter offsetedge.
- Select a planar face on a 3D solid or surface.
- Specify a point location inside or outside the edges of the face, or enter an option to specify an offset distance or a corner style.
- Select another face to offset, or press Enter to end the command.
