Which type of industry is best suitable for an internship in mechanical engineering?

Undergraduate studies in mechanical engineering contain the internship as a part of the curriculum. The sole purpose of this internship is to get an experience of witnessing the real-life applications of the theories being taught in each semester. When it comes to deciding the best suitable industry for an internship when you are having more than one options. 

Area of Interest:

Try to select the industry which is very relevant to your area of interest. This will give you more insight into your existing knowledge. 

Size of organization:

This really makes a difference. If you happen to choose a big organization for an internship, you will be ended up with nothing but getting simply a TAG. The intern has to learn on its own in big organization. No one is free to give you guidance but you have to get it. While on the other hand, the smaller industry has employees who will give you work as an assignment and you will also get some practical exposure towards that things. 

In 2005, I chose Field Marshal (Gujarat) company which makes IC Engines. The company was smaller in size but has employees with big hearts. I learn to assembled the IC engine with the supervision of chief technician. The experience was very amazing. That moment when my assembled machine worked was the best! That was the joy of learning with practical exposure. 

While, in 2006, I joined Excel Crop Care Ltd (Gujarat) as an intern. The organization is big and you will not find any worker who is ready to help you. We were just allowed to be in Library and not permitted to visit the plant. 

This is the difference between smaller and bigger organization. This is my view and experience. Always take a decision to chose the internship industry with the advice of others also.

What is the importance of setting drawing Limits in AutoCAD ?

AutoCAD is a drafting software and requires dimensions to be specified on the drawing which has its overall size depend on the how big or small the drawing is. 

AutoCAD has unlimited space in which one can draw the drawing but in real life, one has to either print it or get it into the physical world so, the one has to prefix the size of the drawing. 

What is LIMITS command?

The LIMIT command in the AutoCAD helps you to set the working space or canvas size into which the complete drawing can be made. When you write LIMITS in the command bar, you will be prompt for Lower Left Corner coordinate location. Normally you can set it to (0,0) while the drawing's Upper Right Corner coordinate require entering coordinate of the point on the upper right corner of the drawing area.

Is it necessary to learn AutoCAD for any Mechanical Engineer?

Any software is a tool for making a task easy in a computer. If you are an engineer, there are plenty of software prepared for the special task. Out of them, AutoCAD is also a very important software.

AutoCAD is all about CAD (Computer Aided Design). If you are a mechanical engineer, you have to design or manufacture a product or component of any machine or mechanism. 

In industry, work is continuously done and one has to rely on the computer instead of a manual task. The same is true for drawing of any product. There are plenty of chances to have an error or many errors in handmade drawing and this will cost a lot for any company. So, design department of any company has AutoCAD in their PCs. They have special persons to do this task. 

Why AutoCAD is must for Mechanical Engineer

If you are in final year of BE or ME or MTech, you should be supposed to prepare an experimental setup (if your project demands). You have to prepare a drawing for entire setup or part of it and hand over to the manufacturer who fabricates or prepare it for you. Most of the manufacturer ask for the AutoCAD file. Because they have CNC machines which can do the task in automatic mode based on the code generated from AutoCAD file of your drawing. 

So, it is very necessary for you to learn AutoCAD if you are a Mechanical Engineer. Even Electrical and Civil people have their own version of AutoCAD. 

Refer the following book on AutoCAD for getting knowledge on it.
