This book is based on the higher engineering colleges “drawing geometry and mechanical drawing” (mechanical) teaching outline prepared at the same time according to the actual need to write the projection transformation commutation method, the intersection of quadric surface in the public symmetry plane The application and so on. Each chapter is followed by exercises. suitable
