Engineering Graphics 2018-19-I Lecture 14 TA101A Engineering Graphics 2018-19-I By Dr. Mukesh Sharma Professor DEPARTMENT OF CIVIL ENGINEERING INDIAN INSTITUTE OF TECHNOLOGY KANPUR KANPUR-208016, INDIA

Spokes in section – See B spoke is though cut but not shown Why - how do you differentiate in A and B?

Lugs in Section – Small lugs A …. Large Lug B Treated differently…

Good practice Aligned views;

Appear right projector but it is not so in sectional view Align the lugs Note small lugs not shown in section Appear right projector but it is not so in sectional view

Appears correct but it is not Correct – align the rib Aligned Section View

Again align the whole

Draw the projection of point A in different planes
