Filetting entities

The FILLET command connects two entities with an arc of a specified radius to create a rounded edge.

You can fillet pairs of line segments, straight polyline segments, arcs, circles, rays, and infinite lines. You can also fillet parallel lines, rays, and infinite lines.

When filleting a polyline, you can fillet multiple segments between two selected segments or you can fillet the entire polyline.

The TRIMMODE system variable defines whether or not to keep the original length of the filleted entities or to trim or lengthen them to the endpoints of the fillet arc.



Filleting two entities or polyline segments

  1. Launch the FILLET command.

    You are prompted: Fillet (radius=10): Select first entity or [fillet Settings.../Polyline/Radius/Trim/Undo/Multiple/selection options (?)]:

  2. Choose the Radius option.

    You are prompted: Fillet radius <current radius>:

  3. Type a value.

    You are prompted: Fillet (radius=new radius): Select first entity or [fillet Settings.../Polyline/Radius/Trim/Undo/Multiple/selection options (?)]:

  4. Select the first entity or polyline segment.

    You are prompted: Select second entity (select with pressed SHIFT to make corner):

  5. Select the second entity or polyline segment.

    The fillet is created.

Filleting all vertices of a polyline

  1. Launch the FILLET command.

    You are prompted: Fillet (radius=10): Select first entity or [fillet Settings.../Polyline/Radius/Trim/Undo/Multiple/selection options (?)]:

  2. Choose the Radius option.

    You are prompted: Fillet radius <current radius>:

  3. Type a value.

    You are prompted: Fillet (radius=new radius): Select first entity or [fillet Settings.../Polyline/Radius/Trim/Undo/Multiple/selection options (?)]:

  4. Choose the Polyline option.

    You are prompted: Select 2D polyline to fillet [selection options (?)]:

  5. Select the polyline.

    The polyline is filleted.
