Module – 1
Introduction to Computer Aided Sketching :
Module – 2
Orthographic Projections :
Introduction, Definitions - Planes of projection, reference line and conventions employed, Projections of points in all the four quadrants, Projections of straight lines (located in First quadrant/first angle only), True and apparent lengths, True and apparent inclinations to reference planes (No application problems).
Orthographic Projections of Plane Surfaces (First Angle Projection Only) :
Introduction, Definitions–projections of plane surfaces–triangle, square, rectangle, rhombus, pentagon, hexagon and circle, planes in different positions by change of position method only (No problems on punched plates and composite plates). 24 Hours
Module – 3
Projections of Solids (First Angle Projection only) :
Introduction, Defin itions – Projectio ns o f right regular tetr ahedron, hexahedron (cube), prisms, pyramids, cylinders and cones in different positions (No problems on octahedrons and combination solid) 24 Hours
Module – 4
Sections and Development of Lateral Surfaces of Solids :
Introduction, Section planes, Sections, Section views, Sectional views, Apparent shapes and True shapes of Sections of right regular prisms, pyramids, cylinders and cones resting with base on HP. (No problems on sections of solids)
Development of lateral surfaces of above so lids, their frustums and truncations. (No problems on lateral surfaces of trays, tetrahedrons, spheres and transition pieces). 12 Hours
Module – 5
Isometric Projection (Using Isometric Scale Only) :
Introduction, Isometric scale, Isometric projection of simple plane figures, Isometric projection of tetrahedron, hexahedron(cube), right regular prisms, pyramids, cylinders, cones, spheres, cut spheres and combination of solids (Maximum of three solids). 12 Hours
Course Outcomes :
After studying this course,
1. Students will be able to demonstrate the usage of CAD software.
2. Students will be able to visualize and draw Orthographic projections, Sections of solids and Isometric views of solids.
3. Students are evaluated for their ability in applying various concepts to solve practical problems related to engineering drawing.
Conducting classes :
Classes may be conducted in two slots/ week of 3 hours each (Instruction 1 hr. + Sketching & Practice 2 hr.)
Scheme of Evaluation for Internal Assessment (25 Marks) :
1. 15 Marks for Class work (Sketching & Computer Aided Engineering drawing printouts in A4 size sheets).
2. 10 Marks for test in the same pattern as that of the main examination. (Better of the two Tests).
All the solutions must be valued on the spot by examining the sketches, display and the hard copies. All the sketches including the computer printouts must be submitted and they must be preserved for one year.
Scheme of Examination:
1. Module -1 is only for practice and Internal Assessment and not for examination.
2. Question paper for each batch of students will be sent online by VTU and has to be downloaded before the commencement of Examination of each batch. The answer sheets will have to be jointly evaluated by the Internal & External examiners.
3. A maximum of THREE questions will be set as per the following pattern (No mixing of questions from different Modules).
All the Best ..!!
