By default, all objects except circles, full ellipses, closed polylines, and splines are trimmed when filleted. You can use the Trim option to specify that filleted objects remain untrimmed.

Setting the Fillet Radius in AutoCAD

The fillet radius is the radius of the arc that connects filleted objects. By default, the fillet radius is 0.500 or the last radius set. Changing the radius affects subsequent fillets but not existing ones.
Chamfering Polylines and Polyline Segments
July 23rd, 2009 — AutoCAD Tutorials
If the two objects you select are segments of a polyline, they must be adjacent or separated by one arc segment.
You can chamfer an entire polyline so each intersection is chamfered. For best results, keep the chamfer distances equal. In the following example, you chamfer a closed polyline by setting both chamfer distances to equal values.

Chamfering by Specifying Length and Angle in AutoCAD
July 9th, 2009 — AutoCAD Tutorials
You can chamfer two objects by specifying where on the first selected object the chamfer line starts. Then specify the angle the chamfer line forms with this object. In the following example, you chamfer two lines so that the chamfer line starts 1.5 units along the first line and forms an angle of 30-degrees with this line.
