To identify the polarity of the physical part, a general rule of thumb is to find out which metal lead wire is longer. For me, if it's important enough to dimension to the header outline on Y why not tie it down by giving X dimension to the edge of the header outline?
Crystals might list their oscillating frequency as drawihg value.
Drag from a connection point on the first shape to a connection point on the second shape. The Engineering Symbology, Prints, and Drawings Handbook was developed to assist nuclear facility operating contractors in providing operators, maintenance personnel, and technical staff with the necessary fundamentals training to ensure a basic understanding of engineering prints, their use, and their function.
Resistors act to impede the flow of the circuit to an extent determined by the resistance value used. Symbols usually resemble specific meaning.
It looks like an "M" with 5 or 6 humps. Could have been given here next to the 1mm pitch value, or next to engineeriny 6mm value between centers of first and last pad.

The user can follow the same path that the signal uses to understand what the signal does or how it is being modified. This information will provide personnel with a foundation for reading, interpreting, and using the engineering prints and drawings that are associated with various DOE nuclear facility operations and maintenance.
You can help Wikipedia by expanding it. Basically, the value of a schematic component calls out its most important characteristic. I can work out most of the dimensions, but the mount pads are confusing me. A complete set of working drawings for the average electrical system in large projects usually consists of: It appears someone else voted down too.

The ability to read and understand information contained on drawings is essential to perform most engineering-related jobs. How to Read Electrical Drawing Learn how to read electrical drawing. I'm trying to understand this mechanical drawing. I asked a question about mechanical drawings a while back.
How to Read Electrical Drawing
What are you looking for? Each component name in an electrical drawing should be unique; if you have multiple resistors in a circuit, for example, they should be named R1, R2, R3, etc. For most symbols, polarity is included in the symbol.
What are you looking for? This chapter will address the information most commonly seen in the non-drawing areas of a nuclear grade engineering type drawing. Answers are supposed to address the question, and if you want to comment on a post there is a specific tool.

You can drag the built-in electrical symbols then connect them easily. I thought I'd answered the question about the pad size. For some components, like resistors, the prefix is just the first letter of the component.
