Engineering drawings are also known as mechanical drawings, manufacturing blueprints and drawings. An engineering drawing helps to define the requirements of an engineering part and conveys the design concept.  \nThe Engineer distributes these drawings to a manufacturing department to produce the parts, to an assembly department to put the parts together, then to any vendors, archives or other company departments. The drawings can include an item or system's geometry, dimensions, tolerances, functions, finish, hardware and material. Basic components of engineering drawing  \nTechnical drawings may have different components depending on the industry, the part and the purpose of the drawing.  \nTypes of lines in engineering drawings  \nAn engineering drawing has many different kinds of lines that indicate different concepts and design ideas. Here’s a list of the types of lines you can find in an engineering drawing:  \nContinuous/drawing line  \nA solid line is the most common type of line and represents an object’s physical boundaries. These are the lines used to draw objects. The line thickness can vary—thicker lines are used on the outside contour and thinner lines are used on the inner contour.  \nHidden line  \nLines that are not visible in the current view are represented by dashes. They represent the edges where surfaces meet but are not directly visible. Hidden lines tend to be omitted from drawings unless they are needed to make the drawing clear.  \nCenter line  \nParts with holes and symmetrical features can be shown by using center lines. A center line indicates a circular feature on a drawing and is characterized by its long-short-long alternating line pattern. They can be used to represent:  \n1 Symmetry  \n2 Paths of motion  \n3 Centers of circles and the axes of symmetrical parts  \nDimension and extension lines  \n1 Dimension and extension tines are thin lines used to indicate the sizes of features on a drawing.  \n2 Dimension lines show the orientation and extent of a specified length or size of an element. They end with arrowheads that terminate at the extension lines.  \n3 Extension lines are used to clarify the points at which a dimension begins and ends and extend toward the element that is dimensioned.  \nBreak line  \nBreak lines show where an object is broken to save drawing space or reveal interior features. Break lines come in two forms:  \nA freehand thick line  \nA long, ruled thin line with zigzags  \nPhantom line  \nPhantom lines are thin long-short-short-long lines used to show the travel or movement of an object or a part in alternate positions. They can also be used to show adjacent objects or features  \nSection line  \nSection lines are used to show the cut surfaces of an object in section views. They are fine, dark lines and are generally drawn at a 45° angle. The type of line can indicate various materials such as steel, copper and brass.  \nCutting plane line  \nCutting plane lines are heavy lines used in section drawings to show the locations of cutting planes.
