##### Curves

Parabola,  Ellipse  and  Hyperbola  by  general and  special methods,  cycloids,  involutes, tangents & normals for the curves

##### Scales

Plain scales, diagonal scales and vernier scales

#### JNTUK R20 Engineering Drawing B.tech Syllabus Unit 2 :

##### Orthographic Projections

Reference  plane,  importance  of  reference  lines,  projections  of  points  in various quadrants, projections of  lines,  line parallel to both the planes,  line parallel to one plane and inclined to other plane. Projections of straight lines inclined to both the planes, determination of true lengths, angle of inclination and traces.

#### JNTUK R20 Engineering Drawing B.tech Syllabus Unit 3 :

##### Projections of planes

regular planes perpendicular/parallel to one reference plane and inclined to the other reference plane; inclined to both the reference planes

#### JNTUK R20 Engineering Drawing B.tech Syllabus Unit 4 :

##### Projections of Solids

Prisms,  Pyramids,  Cones  and  Cylinders  with  the  axis  inclined  to  both  the planes

#### JNTUK R20 Engineering Drawing B.tech Syllabus Unit 5 :

##### Conversion of isometric views to orthographic views

Conversion of orthographic views to isometric views. Computer  Aided  Design,  Drawing  practice  using  Auto  CAD,  Creating  2D&3D  drawings  of  objects using Auto CAD.

##### JNTUK R20 Engineering Drawing B.tech Syllabus Course Objectives :

To  introduce  the  students  to  use  drawing  instruments  and  to  draw  polygons,  Engg. Curves.

To introduce the students to use orthographic projections, projections of points & simple lines. To make the students draw the projections of the lines inclined to both the planes.

The  objective  is  to  make  the  students  draw  the  projections  of  the  plane  inclined  to  both the planes.

The objective is to make the students draw the projections of the various types of solids in different positions inclined to one of the planes.

The objective is to represent the object in 3D view through isometric views.  The student will be able to represent and convert the isometric view to orthographic view and vice versa. Conversion of isometric views to orthographic views; Conversion of orthographic views to isometric views.

The objective is to make the students draw the projections of the plane inclined to both
the planes.

##### JNTUK R20 Engineering Drawing B.tech Syllabus Course Outcomes :

The student will learn how to visualize 2D & 3D objects
