Filleting Shape

---

Filleting means rounding a shape edge.
Shapes that can be filleted are lines, polylines, continuous lines, circles, arcs, ellipses, elliptical arcs, B-Splines, infinite lines and rays.
The following 3 methods can be used to fillet a shape.

• Specifying 2 shapes and filleting these endpoints.
• Specifying polyline and filleting all vertexes.
• Filleting one vertex of multiple lines, polyline, continuous line, rectangle, or polygon.

To display a command parameter to be executed, click / of command parameters, or press Tab key or ← / → key on the keyboard.

1. Click [Fillet] on [Edit] menu.
   Then you will be able to fillet a shape.

Supplemental
▪	You can enter into the shape filleting status by clicking on [Edit] toolbar.

When specifying two shapes

2. Switch the parameter on Command Window to [Shape], and click the first shape to be filleted.
3. Click the second shape to be filleted.

When specifying polyline

2. Switch the parameter on Command Window to [Polyline].
3. Click a polyline to be filleted.

When specifying vertex

2. Switch the parameter on Command Window to [Vertex].
3. Click a vertex to be filleted.

4. Specify a trimming method for shapes when filleting in [Trim Method] on Command Window.
   Trim Both Shapes
   The selected 2 shapes and their vertexes will be trimmed to the endpoint of the specified fillet arc.
   Trim One Shape
   A one line forming the first selected shape and vertex will be trimmed to the endpoint of the specified fillet arc.
   No Trim
   The selected 2 shapes and their vertexes will be filleted without trimming.

Supplemental
▪	When a circle, ellipse, or closed B-Spline is selected, it will not be trimmed when filleting even though [Trim Both Shapes] or [Trim One Shape] is specified.

5. Input a radius of filleted arcs in [Radius] box on Command Window.
   The shape will be filleted at the endpoint of the specified fillet arc.
