# ICSE Syllabus Class 10 Technical Drawing Applications

## Introduction to ICSE Syllabus Class 10 Technical Drawing Applications

The ICSE Syllabus Class 10 Technical Drawing Applications course syllabus comprises topics and chapters that will help students to pursue a career in Engineering, Architecture, and Draftsmanship in future.

The syllabus is relatively brief as compared to other core subjects. The module for the Technical Drawing Applications ICSE syllabus is structured by keeping in mind the guidelines of the ICSE Board.

The syllabus consists of Section A which includes topics around Geometrical constructions based on plane geometry and area, engineering curves, scales, oblique drawings, etc. Section B includes chapters on solids like cylinder, prism, pyramids, cones, isometric drawing topics etc.

As the students could not attend regular school due to the Covid-19 pandemic, the Board decided to reduce the syllabus of Class 10 Technical Drawing Applications. The council has taken severe measures to ensure that the quality of education is not compromised. The ICSE board decided to divide the  syllabus into two semesters, each semester covering 50% of the syllabus.

Students can get the latest updates about ICSE Syllabus Class 10 Technical Drawing Applications on Extramarks’ website or app. Our expert academic team has prepared study materials to help students through their exam preparation journey.
