# RTM Nagpur University BE 1st SEM Engineering Graphics I Syllabus

UNIT – I: (08 Hrs)

Introduction to Engg. Drawing & Curves used in Engineering Practice Introduction , Use of various drawing instruments, lettering, Layout of drawing sheets, sizes of drawing sheets, different types of lines used in drawing practice, Dimensioning – linear, angular, aligned system, unidirectional system, parallel dimensioning, chain dimensioning, location dimension and size dimension. Introduction to scales & scale factor (RF).

Conic sections – Ellipse, Parabola, Hyperbola, (No Directrix – Focus Method), Cycloid, Involute & Archimedean Spiral.

Basics of Orthographic Projections Basic principles of orthographic projection, reference planes, concepts of four quadrants, methods of orthographic projections – First angle projections, Third angle projections, conventions used to represent methods of orthographic projection.

Projections of Points and Lines, Projections of points in all possible positions w.r.t. reference planes, projections of lines when it is perpendicular to one of the reference planes, when line is inclined to one & parallel to other reference plane, lines inclined to both reference planes. (Lines in First Quadrant Only), simple problems on straight lines.

UNIT – II (08 Hrs)

Projections of Planes

Projection of planes when it is parallel to one of the reference planes, lying in reference plane, when it is perpendicular to one & inclined to other reference plane, when it is inclined to both reference planes. Use of Auxiliary Plane method for solving the problems.

Projections of Solids

Projections of solids when axis is perpendicular to one of the reference planes , when axis is inclined to one & parallel to other reference plane, when axis is inclined to both the reference planes, projections of cube, right regular prisms, right regular pyramids, right circular cylinder, right circular cone, tetrahedron.

UNIT – III (07 Hrs)

Orthographic Projections

Conversion of pictorial view into orthographic views.

UNIT – IV ( 07 Hrs)

Isometric Projections

Definition of Isometric view/projection, Isometric scale to draw Isometric projection, Non-Isometric lines, construction of Isometric view from given orthographic views and to construct Isometric view of combined two simple solids (axes vertical & coinciding) such as Cube, Pyramid, Prism, Cone, Cylinder & Sphere.

(NOTE – ONLY FIRST ANGLE METHOD OF PROJECTIONS SHOULD BE USED)
