Drafting of various geometries using Chamfer, Fillet tool in AutoCad

Aim: To draw the given drawings using Autocad 2023

Introduction: Autocad is a commercial Computer Aided Design(CAD), It is marked and developed as Autodesk. It was first released on december 1982. Autocad derived from a program, which was beganed in 1977 and then released in 1979 called as Interact CAD, and also called in early documents od autocad as microCAD, Auto desk cofounder was Michael Riddle.

The first version of cad was released in december 1982 and was supported on CP/M-80 computers, By march 1986 Aotocad has became most uniquitous cad program worldwide. The file format of autocad was .dwg, and its interchange file format to DXF, have become a standard. Autocad was included support for .dwf, a format developed and promoted by Autodesk, for publishing CAD date. In year 2022 the Autocad 36th major version was released and the 12th consecutive year of Autocad foe Mac.

CAD is a technology which replaces manual drawing with automated process, if you are a drafter, desingner, architect or engineer you have been used 2D or 3D CAD programs i.e., Autocad or Autocad LT software. Autocad helps you in draft construction documentation, explore ideas for design, viaualise concepts through photorealistic renderings and gives how a design performs in real world.

Autocad mailnly used by industries, architects, engineers, city planners, project managers, graphic designers and other professionals.

Steps:

1. Open new file in Autocad 2023, Type UNITS, use decimal and take meters
2. Then LIMITS, Limits of lower left corner give (0,0) and limits of upper right corner (10,10)
3. Type DS (drafting settings) and go to snap and grid ON snap and grid, give snap X and Y spacing as 0.1, and Grid X and Y spacing as 0.1 and major lines are taken at every 5 minor lines.
4. Take line command and first point is (0,0) and next points are (@3,0) (@2.12<45) (@2.83<135) (-2,0) and then close.
5. Now take circle, center as (1.5,1) and dia 1.2 and again circle at (1.5,2.5) center and dia is 0.8
6. Then using Dimension and mark the lines dimension and angle by taking Dimangular and by Dimdia to mark diameter of circle, To modify dimensions- Go to dimenstion in tool bar and then to dimension style.

8. Use Trim command and remove all unnecessary lines and a Square of 3' is formed.
9. Now select the square and Rotate it for 45 degrees
10. Then using Dimension and mark the lines dimension,To modify dimensions- Go to dimenstion in tool bar and then to dimension style.
