Fillet

 
Connects two lines (either single or double lines) or arcs (except elliptical arcs) with a smoothly fitted arc. The filleted objects do not have to intersect, and they can overlap. The result is a rounded corner.
Note: You can also fillet corners with the Edit Tool (see Editing Linear Objects). To apply fillets to a 3D polyline, see Bolt.

1. Enter the fillet radius in the Inspector Bar.
2. Select the first line or arc to fillet.
3. Select the adjacent line or arc. The corner is rounded. Local menu options:  Polyline: Fillets all corners of a polygon or polyline in one step.
4. Enter the fillet radius in the Inspector Bar.
5. Select the multi-segmented object you want to fillet.
6. Select Polyline from the local menu or Inspector Bar. To Lines and Arcs: The resulting object is broken into lines and arcs. (The default, To Polyline, leaves the filleted object as a single object, even if the objects were originally separate.) !worddavc0c42bdff3e357e93a9c495124744d4c.png|height=54,width=145!In Select mode, you can verify that the fillets are separate objects. !worddavcb05cd19cdb85b6e76ab98b8921613c3.png|height=113,width=206!The other local menu options apply to double lines. See Double Line Options.Note: You can use Fillet on splines and Beziers, however the extension will be straight element of the curve, not curved continuations as they are with arcs.Note: You can use Fillet to change an arc on a polyline, but only on arcs that are between two straight segments. Simply select the two straight segments and the arc will be adjusted to the radius of the fillet.
