Offset sketch geometry

Learn how to use the Offset tool to offset sketch geometry to a specified distance in an active sketch in Fusion.

Note: Before you can modify sketch geometry, you must use the Create Sketch tool and use the create tools to create new sketch geometry or right-click an existing sketch and select Edit Sketch to enter the Sketch contextual environment.

1. On the Sketch contextual tab, select Modify > Offset .

2. In the Canvas, select the sketch curve, a chain of connected sketch curves, or a sketch profile to offset.

3. Specify the distance to offset or drag the distance manipulator handle in the canvas.

4. (Optional) To offset on both sides of the selected geometry:

   1. Check Two Sides.
   2. (Optional) Check Link Offsets to link the offset parameter dimensions of the two sides so when you change one, the other updates to match.

5. (Optional) Check Match Topology to limit the rage of the offset distance so the child offset curves match the topology of the parent curves.

   Note: To select offset-constrained curves, Match Topology must be checked.

6. Click OK.

The offset geometry, offset distance dimensions, and offset constraints display in the canvas.

Tips

• Valid selections highlight when you pause the cursor over them.
• If you select an ellipse by clicking near its major or minor axis, the offset result is an ellipse. The axis displays in the preview, and the offset distance is the same at the major and minor axes. Since an ellipse is created, the offset distance varies around the rest of the ellipse.
• If you select an ellipse by clicking away from its major or minor axis, the offset result is an oval. The axis does not display in the preview, and the offset distance is the same around the entire ellipse.
• To remove the association between the original sketch geometry and the offset sketch geometry, delete the offset glyph.
• To maintain the offset relationship, but unlock the offset distance, delete the offset dimension.
  • To restore the dimension, right-click the offset glyph, then select Add Offset Dimension. You can also add a regular sketch dimension if you have deleted the offset dimension.
• You cannot create offset geometry from offset sketch curves.
