PART AND ASSEMBLY DRAWING

Industrial Drafting 2014 Ramón Rubio

CONCEPT | U2 METHODOLOGY

An assembly drawing is…




…global information




A part drawing is…detail information




The information includes: •  All necessary drawing

views to fully defined the shape

•  Dimensions •  Tolerances •  Material •  Any specific notes:

painting, coating, hardness, surface finishes, surface roughness

Which is the scale if I wanted to draw it in a

A3 sheet?
