INTRODUCTION

This week we focus on the Development topic. Developments are a key topic in Junior Cycle Technical Graphics and the Leaving Certificate progression is not that much of a leap. This topic does not come up often but it can be examined in Section A or Section B. Developments are also a very important part of Surface Geometry in Section C.

SYLLABUS LEARNING OUTCOMES

(Leaving Certificate Design and Communication Graphics Syllabus, 2006)

INTERSECTION AND DEVELOPMENT OF SURFACES
