Our institute recommended this after completing a orthographic projection assignment (that too sectional) and too after completing Machine Drawing.. Once asked, Will the Ribs have hatching lines...just to clarify ones doubt...Answer one got was like asking Will A have straight line or it can be curve....answer was there are 26 alphabets, 5 vowels and 21 consonants, there are many letter which use curve and and straight line.. Alphabets can be used for writing words, words used for writing sentences, sentences used for writing paras, paras used for making stories, stories used for writing books, books used for reading. Ofcourse, I being a boy will have to study as genuine questions maybe asked...again as I BEING A BOY, in our viva, invigilator wont ask- WHAT IS YOUR FAVORITE COLOUR.....HOW MANY MEMBERS ARE THERE IN YOUR FAMILY......DO YOU HAVE BOYFRIEND
