Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Aim:- To draft the various geometry using chamfer, fillet tool in AutoCAD

Introduction:-

In AutoCAD we use different tools like circle, offset, move, chamfer, fillet, rotate, trim, mirror etc.,

Chamfer

• Chamfer command is used to create the slanted edge between the two connected line or polyline
• Here we should give 2 values for creating the chamfer in geometry these two values moves in alternative way

Fillet 

• Fillet command is used to create the smooth arc tangent between two objects in 2D and it's used to create round edge between the adjacent lines in 3D
• Fillet can be created between two same objects or different objects

 

Procedure:-

• Go to start menu, click on Start drawing
• Type stratup (Enter) in command line 
• Enter the new value of start up:1
• Go to application menu and select new or type new in command line
• In the "create new drawing" dialogue box contains imperial  type of systems and metric type of system 
• We select the metric system in the "start from scratch" option
• After that in Advance setup option select the decimal unit system in the units 

The above procedure should be followed every time when the new sheet is opened 

                               

                               Entering the start up command in the command line       

            

                             

                             Entering the value 1 for the start up

 

                                    

                            When we go to the new file then we get this file select the metric from start from scratch

              

                            

                           Then advance setup setting should be done by clicking OK 

 

                                 

                          Keep the units in decimal and adjust precision then click next            

 

                           

                           Keep angle in decimal degree and adjust precision then click next

 

                             

                          Select the angle measurement in east and click on next                    

                          

                            Select angle direction in counter clockwise and click on next

 

                           

                           Keep the width as 12m and length of 9m as default and click on finish
