- 4. Version of AutoCAD • AutoCAD software was firstly launched by Autodesk company in Dec. 1982. • It comes in India in 1988. • The first version of AutoCAD was R1 after that R2,R3,R4…………… and so on. • In 2000,Autodesk launched a version of AutoCAD 2000 after that 2001,2002…… so on. • This time, we have the latest version of AutoCAD is 2018. • Latest version is easy to use and over come the difficulties of old version.
- 5. DRAWINGS WE CAN DEAL IN AUTOCAD TYPES OF DRAWINGS: 2 Dimensional Drawings •Orthogonal Drawings •Isometric Drawings •Layouts 3 Dimensional Drawings •Solid Modeling •Mesh Modeling •Surface Modeling 2D 3D ISOMETRIC
- 6. Way to Provide command 1.BY COMMAND PROMPT 2.BY TOOLBAR 3.BY PULLDOWN MENUS
- 7. HOW AutoCAD WORKS ? AutoCAD works on co-ordinate system. Every thing that we draw in AutoCAD is exact. All object drawn on screen is based on simple X-Y co- ordinate system. In AutoCAD it is known as world co-ordinate system (WCS). There is so many commands like copy, move ,rotate ,mirror in 2D, path array , rectangular array, polar array & more. Using line , arc , circle , rectangle , ellipse & polygon , so many drawing of different type can be made.
- 8. • Absolute Coordinate System = exact x,y position on the screen. • Relative Coordinate System = movinng from a known position @x,y to the new position. • Polar Coordinate system = moving from a known position @distance < theta (θ) to new position. • References= Using ortho, polar, osnap, otrak, grid, snap, infer etc INPUT METHODS
- 9. The UCS and WCS • The AutoCAD world is 3 dimensional. However, if we want to draw a 2d object, such as a plan or a section, we will use only 2 dimensions (x and y). • WCS (world coordinate system) is the imaginary plane that is parallel to the ground. It is the default coordinate system. • Modifications made to the World Coordinate System (WCS) result in a User Coordinate System (UCS). It is the plane that you work on. It enables the user to draw 3 dimensional objects. • To create a new UCS, type ucs on the command window, then say New and specify 3 points on your new UCS plane.
- 10. Some 2D Commands Chamfer 2. Fillet Copy 4. Mirror
- 11. 2D Commands Scale 2. Array Extend 4.Join
- 12. Hatching • Hatching is used to add shaded patterns to objects and shapes within an Autocad drawing. Hatch patterns can be used to indicate a material to be used, such as a concrete hatch. • You will pick: – Pattern – Scale – Angle – points
- 13. 3D Modeling
- 14. Some 3D Object
- 15. 3D Commands EXTRUDE Extrusions can extend in the Z direction or be set to taper or follow a path. You can extrude an open or closed object to create a 3D surface or solid. SHADEMODE It is used for setting of view style of diagram, which may be….. 1.2D wireframe. 2.Realistic. 3.3D Hidden.
- 16. 3D Commands REVOLVE Creates a 3D solid or surface by REVOLVE an object around an axis. SWEEP Creates A solid or surface by sweeping an open or closed, planar or non-planar curve (profile) along an open or closed path. Open curves create surfaces and closed curves create solids or surfaces.
- 17. Use of Extrude Command • If you “Extrude” a surface into the third dimension, you simply add a thickness in section. This basically is same as creating a “solid” object . Extrude 5 units 5 units Extrude -4 units 4 units
- 18. Targeted learning goal in software • Standard Syllabus 1. User interface 2. Input methods 3. Draw 4. Modify 5. Layer 6. Block 7. Annotation 8. 3D Solid modeling 9. 3D Solid editing • Advance Syllabus 1. Parameters 2. Dynamic block 3. Xref 4. Design centre 5. Layout 6. Tool pallet 7. Macro 8. Action recorder 9. Lisp 10. Rendering 3D model 11. 3D Mesh modeling 12. 3D Surface modeling 13. 3D model editing 14. 3D view creation
- 19. Benefits of AutoCAD Quickly create designs. Improved quality over hand drafting. Modification becomes easy. More Accuracy. Easy to transfer. Long time save.
