Government of Karnataka Department of Technical Education Board of Technical Examinations, Bengaluru COURSE DESIGN, DELIVERY AND ASSESMENT
Course Title: Computer Aided Engineering Drawing (CAED)
Course Code: 15AN23P
Credits (L:T:P) : 0:2:4
Core/ Elective: Core
Type of course: Demo & Assignments
Total Hours: 78
CIE- 25 Marks
SEE- 50 Marks
Pre-requisites: Engineering Drawing.
Course Objectives: 1. Now a day a manual drafting is obsolete in industry. Computers being the inevitable part in an engineer’s life due to its inbuilt characteristics which helps him to do various task with acceleration. 2. Using computers and CAD software it is easy to create and modify drawings ultimately it saves time. It also may be useful to generate assembly and manufacturing drawings. 3. In mechanical industry operating skills are required for computer aided drafting operations of machine components, handling of printers & plotters. This subject is also useful to apply concepts in 3 D modeling.
COURSE OUTCOMES On successful completion of the course, the students will be able to:
Course Outcome CO1 Interpret and Draw, edit and modify 2D CO2
Give dimensions, tolerances and geometrical tolerances
CO3 Create Isometric Views and 3 D drawing ,when orthographic views of simple machine parts CO4 Plot Assembly 2D drawings

Level 3- Highly Addressed, Level 2-Moderately Addressed, Level 1-Low Addressed. Method is to relate the level of PO with the number of hours devoted to the COs which address the given PO. If >40% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 3 If 25 to 40% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 2 If 5 to 25% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 1 If < 5% of classroom sessions addressing a particular PO, it is considered that PO is considered not-addressed.
