AIM:

Drafting of various geometries using Chamfer,Fillet tool in AutoCAD.

INTRODUCTION:

• AutoCAD consist of a number of drawing and modification tools.Among the modification tools are the Chamfer,Fillet,Offset,Object,Snap,Rotate,Copy,Move,Mirror,Trim,Extend,and Join.

1. CHAMFER:

• A bevel or chamfer is an angled line that meets the endpoint of two strating 2d points .a slope transition between two surfaces or adjacent faces on a 3D solid.
• The distance and angles that we specify are applied in the order that we select the objects.

2.FILLET:

• Around or fillt is an arc that is created as a tangent between 2D objects.Acurved transition between two surface or adjacent faces on a 3D solid.

3. OFFSET:

• It is used to create concentric circles ,parallel lines and parallel curves.

4. OBJECT SNAP:

• Object snap provides a way to specify precise location,such as end point ,midpoint etc.on objects whenever we are prompted for a point within a command.We can offset an object at a specified distance or through a point.

5.ROTATE:

• This tool rotates objects around a base point. An object can be rotated either by entering the angle of rotation,or drag the object around its base point and specifying a point location to which we want to rotate the object.we can also enter cto create a copy of the selected object from a specified reference angle to an absolute angle.

6.COPY:

• This command copies objectes at a specified distance in a specified direction .with the copy mode system variable,we can control whether multiple copies are to be created automatically.

7.MOVE:

• It moves object a specified distance in a specified direction.we can use coordinate ,grid snap,object snaps and other tools to move objects with precision.

8. MIRROR:

• This command is used to create a mirrored copy of selected objects.using this command we can create objects that represent half of a drawing,select them,and mirror them across a specified line to create the other half.

9. TRIM:

• It trims extends objects to meet the edges of other objects.There are two modes that can be used to trim objects viz quick mode and standard mode.

10.EXTEND:

• This command extend the object to meet the edges of other objects.To extend objects,we first need to select the boundaries and then press Enter and select the objects that we want to extend.to use all objects as boundaries,we press enter at the first select objects prompt.

11.JOIN:

• It joins the endpoints of linear and curved objects to create a single object.A series of finite linear and open curved objects at their common endpoints are combined to create a single 2D or 3D object.The resulting object depends on the types of objects selected,the type of object selected first and whether the objects are coplanar.
