In technical drawing, what does the term "orthographic projection" refer to?

• A method of representing three-dimensional objects in two dimensions

• The actual size of the object

• The shape of the object when it is flattened out

What is the purpose of net developments in technical drawing?

• To create a 3D model

• To show the true length of an object

• To represent the unfolded shape of a 3D object

• To add dimensions to the drawing

In technical drawing, what does the term "true length" refer to?

• The length of the object as measured in a 3D model

• The length of the object as seen from a specific angle
