Hidden Lines: Broken line of medium thickness that shows edges of an object or outlines not visible to the eyeĬenter Line: Broken line made up of short and long dashes alternately spaced that show the center of circles, arcs, and symmetrical objects.Įxtension Line: Extension lines are fine lines that extend from the object with slight break between the show dimensioning points.ĭimension Line: fine lines with arrowheads, unbroken except where the dimension is placed that show distance given by the dimensions. All the lists provided below are in alphabetical order for easy reference, you can use this as a guide to help you understand your engineering drawing.Object Lines: Represents a thick solid line that shows the visible shape of an object or part. The charts below are a complete list of abbreviations and symbols in engineering drawings. An engineering drawing often tells the specific requirements and detail, such as:
Once you understand the meaning and definition of the symbols and abbreviations, you’ll pick up and use the engineering drawing with ease. Note that the same abbreviation may represent different meanings in different types. International Engineering Standards may be different from countries and applications applied, like International (ISO), USA (AISI, ANSI, ASTM, SAE, AMS), UK (BS), France (AFNOR), Germany (DIN, WR), Australia (AS), Sweden (SS), Korea (KS). Technical standards are the definition and glossary of abbreviations, symbols, and acronyms that may be found on engineering drawings.
