NOTE
DEVELOPMENT 1
Development involves using construction techniques to transfer the design of an object onto a flat surface, typically a sheet, so that when the sheet is folded along specific lines, the intended object takes shape. This helps in creating flat patterns that can be used for manufacturing various objects.
Types of development
Basically, there are three types of development commonly employed in the development process:
However, due to the intricacy associated with triangulation, the focus often shifts to mastering the parallel lines and radial lines techniques, which are more manageable and widely applicable.
Applications of development
The practical applications of development span across various aspects of daily life, including household, office, and industrial settings. However, the following are applications of development in technical drawing:
