In engineering drawings, understanding different types of lines is important. The most important ones include solid lines (representing visible edges or boundaries of objects), dashed lines (indicating hidden or invisible parts behind other elements), dotted lines (used for centerlines or symmetry), and thin lines (for dimensions, extension, and leader lines).

A year later, six-year-old Richard visited the 1939 New York World's Fair, where his father worked in the transportation building, and saw two more pieces of inspiration: an enormous model railroad layout and a marble machine. "To this day, I could probably draw a very detailed picture of what [that marble machine] looked like," said Richard.

Engineering drawings are the most important deliverables that a design engineer produces. They provide all the instructions needed to make your parts exactly as you intended. ... In addition, many machine shops refuse to quote jobs that have bad drawings, because nothing is more disruptive to them than having to call the engineer for missing ...
Students explore methods employing simple machines likely used in ancient pyramid building, as well as common modern-day material transportation. They learn about the wheel and axle as a means to transport materials from rock quarry to construction site. They also learn about different types and uses of a lever for purposes of transport. In an open-ended design activity, students …
RM2E2HFKK – An old engraving of a man at a drawing bench in the 1800s. It is from a Victorian mechanical engineering book of the 1880s. The machine is used to draw strips of metal to an exact thickness by pulling it through a restricting opening – in a similar way that wire is drawn to the correct thickness.
"Marblevator, Mechanisms" is the latest in my Marblevator series of marble machines and features the quickest marble lift mechanism I've ever designed. My fascination with gears, mechanisms, marble machines and history formed my inspiration for this model. UPDATE: added "Base 2.stl" with a slightly longer track.
Using CAD is favourable because it allows individuals to give instructions directly to manufacturing machines. This provides more convenience and efficiency. With CAD software, you can either create a drawing from nothing or create a 3D model and then translate this into a drawing. ... Engineering drawings can be in 3D or 2D and can show ...
