J. N. Green Technical Drawing PDF Download
Technical drawing, also known as engineering drawing or drafting, is a detailed, precise diagram or plan that conveys information about how an object functions or is constructed. Technical drawing is essential for communicating ideas in industry and engineering. To make the drawings easier to understand, people use familiar symbols, perspectives, units of measurement, notation systems, visual styles, and page layout. Together, such conventions constitute a visual language and help to ensure that the drawing is unambiguous and relatively easy to understand.

Technical Drawing Basics
Before we dive into J. N. Green's books, let's review some of the fundamentals of technical drawing.
What are the elements and conventions of technical drawing?
A technical drawing consists of several elements, such as:
Table: A table is a structured set of data made up of rows and columns. A table allows you to quickly and easily look up values that indicate some kind of connection between different types of data.
Cell: A cell is a unit of information in a table. Each cell is defined by a <td> tag.
Row: A row is a horizontal group of cells in a table. Each row starts with a <tr> tag and ends with a </tr> tag.
Column: A column is a vertical group of cells in a table.
Header: A header is a cell that describes the content of a row or column. A header cell is defined by a <th> tag.
Caption: A caption is a title or description for a table. A caption is defined by a <caption> tag.
Besides these elements, there are also some conventions that make technical drawings more consistent and clear, such as:
Scale: A scale is a ratio that shows how much an object has been reduced or enlarged on a drawing compared to its actual size.
Symbols: Symbols are graphical representations of objects, actions, or concepts that are commonly used in technical drawings.
Perspectives: Perspectives are Perspectives are ways of showing the three-dimensional shape and position of an object on a two-dimensional plane. There are different types of perspectives, such as isometric, oblique, and perspective.
Units of measurement: Units of measurement are standardized quantities that are used to express the size, length, weight, or capacity of an object or phenomenon. Some common units of measurement are meters, kilograms, liters, degrees, etc.
Notation systems: Notation systems are sets of symbols and rules that are used to represent information in a concise and unambiguous way. Some examples of notation systems are mathematical notation, chemical notation, musical notation, etc.
Visual styles: Visual styles are the choices of colors, fonts, shapes, lines, textures, and other graphical elements that are used to create a certain mood or impression in a technical drawing.
Page layout: Page layout is the arrangement of text, images, tables, and other elements on a page. Page layout affects the readability and attractiveness of a technical drawing.
