Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Drafting of various geometries using chamfer, Fillet tool in Autocad

Drawing-1

Aim:

To determine drafting of various geometric using Chamfer, fillet tool in autocad

Introduction:

• Autocad offers various tools to perform different tasks. The various tools which are used for drafting in.
• This Project are briefly described here.

These tools include-

Modification tools: Chamfer,, fillet , offset, rotate, object snapping, trim and extend, Lengthen, Mirror and join

CHAMFER:

• A bevel or chamfer is:

An angled line that meets the endpoints of two straight 2D objects.

A Sloped transition between two surfaces or adjacent faces on a 3D solid

• The distances and angles that you specify are applied in the order that you select the objects.

Command Used: Chamfer

FILLET:

• The fillet tool helps form round corners between any two entities that form a sharp vertex.
• 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, 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 colourand line types.

OFFSET:

• Create concentric circles, parallel lines and parallel curves.
• Command used: OFFSET 'O'

ROTATE:

• Used to rotate object in our drawing around aspecifiesd base point.To determine the angle of rotation, we can enter an angle value, drag using the cursor, or specify a reference angle to alignto an absolute angle.
• Command Used: ROTATE

OBJECT SNAP:

• Object snaps provide a way to specify precise locations on objects whenever you are prompted for a point within a command
• For example, you can use object snaps to create a line from the centre of a circle to the midpoint of another line. The available options are endpoint (end), midpoint(mid), centre(cen), geometric centre(gcen), nearest(nea), quadrant of circle(quad), intersection, perpendicular, tangent,parallel, extension, apparent intersection nodes, insertion points.
• Command Used: OS-Object Snap

TRIM and EXTEND:

• Trims objects to meet the edges of other objects
• Quick Mode.To trim object select the objects to be trimmed individually press and drag to start a freehand selection path, or pick two empty locations to specify a crossing fence.All object automatically act as cutting edges. selected objects that can't be trimmed are deleted instead.Standard mode To trim objects first select the boundaries and press enter. Then select the object to be trimmed. To use all objects as boundaries press enter at first select objects prompt.
• Command Used: TR
• Extends objects to meet the edges of other objects.To extend objects, first select the boundaries then press enter and select the objects that you want to extend.To use all objects as boundaries.Press enter at the first select object prompt.
• Command Used: EX

LENGTHEN:

• Changes the length of objects and the included angle of arcs.
• You can specify changes as a percentage, an increment or as a final length or angle. LENGTHEN is alternative to using TRIM or EXTEND
• Command Used: Lengthen

MIRROR:

• Create a mirrored copy ofselected objects
• We can create objects that represent half of a drawing select them and mirror them across a specified line to create the other half.

• Command Used: MIRROR

JOIN:

• Joins the endpoints of linear and curved objects to create a single object. Combines a series of finite linear and open curved objects at their common endpoints to create a single 2D or 3D object. The types of object that results repends on the types of objects selected the types of object selected first and whetherthe object are coplanar.
• Command used:MIRROR
