Engineering/Architectural Graphics - part I - Orthographic projection

By Prof. Avlokita Agrawal   |   IIT Roorkee
Learners enrolled: 246
All phases of manufacturing or construction require the conversion of new ideas and design concepts into the basic line language of graphics. Therefore, there are many areas (civil, mechanical, electrical, architectural and industrial) in which the skills of drafting play major roles in the design and development of new products or construction. Engineering Graphics is the language of architects and engineers. Just like any other language, we need to learn the vocabulary and grammar in order to be able to communicate. Engineering graphics course is the course which imparts vocabulary and grammar for the language of architects and engineers. Engineering graphics has two distinct components – 2D and 3D. In this course we will cover the topics related to 2D in graphics.
This course is designed to address: • to enable you to communicate in engineering/architectural language of drawings • to prepare you to use the techniques, skills, and modern engineering tools necessary for engineering practice
The student will learn : • Introduction to engineering design and its place in society • Exposure to the visual aspects of engineering design • Exposure to engineering graphics standards • Exposure to engineering communication

Instructor bio

Prof. Avlokita Agrawal

IIT Roorkee
I Am Dr. Avlokita Agrawal. I earned Bachelor of Architecture degree from IIT Roorkee in 2003 and PhD from IIT Roorkee in 2010. Right from college, the subject which most interested me were climatology and passive designing which were taught to us by one of the most accomplished teachers of those times, Dr. M R Sharma and Dr. I C Sharma, both from CBRI. After B Arch, I pursued PhD where I studied Impact of Vaastushastra on thermal comfort in traditional Havelis of Rajasthan. While pursuing PhD and post completion of PhD, I worked for companies like Asahi India Glass (where I headed their Green Design Division) and Honeywell international (where I worked in Corporate Affairs division with a focus on building energy efficiency vertical). In corporate jobs, I was mainly working toward various aspects of building energy efficiency. After joining back academics, I have mainly taught subjects like Sustainable Built Environment. I also manage the IGBC student chapter at IIT Roorkee.

Course certificate

The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.
The exam is optional for a fee of Rs 1000/- (Rupees one thousand only).
