Drafting of various geometries using Chamfer, Fillet tool in AutoCad
AIM: To draw the given geometry in autocad using Chamfer and Fillet tool.
INTRODUCTION
Fillet Tool :- 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. 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.
Chamfer Tool :- A chamfer can be defined by selecting two objects of the same or different object types: lines, polylines, rays, and xlines.If the two selected objects are on the same layer, the line defined is created on that layer. Otherwise, the line is created on the current layer.
