AutoCAD About Create Fillets
A round or fillet is
- an arc that is created tangent between two 2D objects.
- a curved transition between two surfaces or adjacent faces on a 3D solid.
In this example, an arc is created tangent to the selected lines, which are trimmed to meet the endpoints of the arc.
Create 2D Fillets
A round or 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.
If the two selected objects are on the same layer, the arc defined is created on that layer. Otherwise, the arc is created on the current layer. The layer affects object properties including color and linetype.
The following prompts are displayed when creating a 2D fillet.
Select the first of two objects or the first line segment of a 2D polyline to define the fillet.
