What is a shortcut you can use to create section views of threaded parts?
What will be an ideal response?
You can use a shortcut in the representation of a threaded part, such as a pneumatic fitting. A thread on the outside of a bolt or screw or the inside of a nut has many complex curved surfaces that would result in a very complicated drawing, especially if it were created with manual instruments or 2-D CAD. There are much simpler schematic representations: they are easier to construct and have very little loss of information, especially since thread sizes are mostly standardized based on the diameter of the part. A note and arrow are required to specify the precise thread sizes. Methods for the complete specification of thread sizes can be found in most machinists' or engineers' handbooks.
