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.
