# CBSE Curriculum For Class XI Engineering Graphics

## CBSE Curriculum Class XI Engineering Graphics

CBSE Curriculum Class XI Engineering Graphics-This subject is advisable for students who want to opt for engineering or as architects or designers as profession. The course syllabus for engineering graphics for CBSE thus is apt and well prepared for students.The main motive for this syllabus is to make the students understand the fundamental principles and wide applications of engineering graphics . The students could develop in them  a very clear concept and perception. Through the course preparation the students will also be able to gain the skill of expressing 2 and 3 dimensional objects into a professional language. They are trained so that they could neatly draw sketches which is a job requirement. Thus obtaining speed and accuracy in drawing instruments.
