What are the three main parts of a blueprint?
Blueprints are documents that contain three major elements: the drawing, dimensions, and notes. The drawing illustrates the views of the part necessary to show its features. Together, the extension and dimension lines on the drawing indicate dimensions and specific tolerance information of each feature.

Why is it called a blueprint?
Way back when, the way to copy drawings was to lay a sheet of tracing paper or other sufficiently transparent medium over the original and trace it. A process was developed in the nineteenth century that yielded a copy with the image in white lines on a blue background, which is where the name “blueprint” came from.

What is true radius?
True Radius. On a 2D orthographic drawing, where a radius is dimensioned in a view that does not show the true shape of the radius, TRUE is added before the radius dimension. This practice is applicable to other foreshortened features as well as radii.
