Advantages and disadvantages of AutoCAD.

Advantages of AutoCAD: 1. A mid range Software 2. User Friendly 3. Fulfills most of the professional needs of a mechanical engineer 4. Lots of Time saving (but not always) 5. Paperless Environment 6. Ease of Accuracy — e.g. joining of lines head to head is not possible manually with desired accuracy 7. Easy to edit 8. Ease of Repetition / Addition 9. Reproduction of Drawing is easy, rapid and reliable in terms of dimensional accuracy and precision. 10. 2D and 3D production of drawings is very easy. 11. Zoom Command Facility allows us to see the minute details on larger scale view. 12. A facility of Modeling and making Parts library is available. 13. Parent – Child relationship allows multiple editing in single command, means if one part is edited all other linked parts are auto edited 14. Layers option allows us to hide or show some specific details of a complex assembly drawing for clear understanding. 15. There is no limitation of a Drawing size. You can draw a...
