Engineering/Architectural Graphics – part II – Isometric and Axonometric Drawings

By Prof. Avlokita Agrawal   |   IIT Roorkee
Learners enrolled: 661
ABOUT THE COURSE : All design and construction (manufacturing) activities require conversion of ideas and concepts into drawings for their execution. Large part of this job is done through Orthographic Projection (which was covered in Part I of this course). However, most of the times, 2-D drawings are difficult to apprehend in the absence of a 3-dimensional representation of the same. A 3-D visualization adds clarity to the idea and makes the process of design to construction much simpler. There are several techniques available for visualizations.

The two methods discussed here in this course are the most widely accepted ones. This course will teach-
1.Isometric projections
2.Axonometric projections

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.
