Rounds the edges of two 2D objects.
A round or fillet is an arc that is created tangent between two 2D objects.
A fillet can be created between two objects of the same or different object types: 2D polylines, arcs, circles, ellipses, elliptical arcs, lines, rays, splines, and xlines.
Create 2D Fillets
In this example, an arc is created tangent to the selected lines, which are trimmed to meet the endpoints of the arc.
To fillet objects:
- Click FILLET or enter F in the Command Line.
- Choose Radius in the command options, enter a radius, and press Enter. This number will be the radius of the arc between the two objects you fillet.
- Select the first object.
- Select the second object.
If the objects intersect, the objects are trimmed based on their intersection point. If the objects do not intersect, the objects are extended until they intersect.
The following prompts are displayed when creating a 2D fillet:
- First object
- Second object
- Radius
First Object
Select the first of two objects or the first line segment of a 2D polyline to define the fillet.
Second Object
Select the second object or line segment of a 2D polyline to define the fillet.
If the selected objects are straight line segments of a 2D polyline, the line segments can be adjacent to each other or separated by one other segment. When the selected segments are separated by a segment, the segment that separates them is removed and replaced with the fillet.
The direction and length of the arc created is determined by the points picked to select the objects. Always select an object closest to where you want the endpoints of the fillet to be drawn.
When a circle is selected, the circle is not trimmed; the fillet drawn meets the circle smoothly.
Line segments that are too short to accommodate the fillet radius are not modified.
Radius
Sets the radius for subsequent fillets; changing this value does not affect existing fillets.
A radius value of zero can be used to create a sharp corner. Filleting two lines or line segments of a 2D polyline with a radius of zero extends or trims the objects so they intersect.
