This book is edited and edited by the second heavy machinery factory and compared with the Oriental boiler factory. Published by Sichuan People’s Publishing House. The content is to introduce the thick-walled container or thick-walled geometry through the pieces in the unfolded material to deal with the characteristics of the thickness of the plate, obtained through the thickness of the new geometrical contour line projection and expansion to eliminate the impact of thickness. This book can be used as a cold riveting workers, lofting workers, sheet metal working methods book, but also as a technical school teachers and students reference book. About 200,000 words, divided into seven chapters. The first chapter, the concept of thickness treatment; The second chapter, the concept and principle of combining lines; The third chapter, parallel line drawing method of plate thickness treatment; The fourth chapter, radiating plate thickness treatment; The fifth chapter, Triangle painting
