________ are thick, solid lines that show the visible edges, corners, and surfaces of a part
Object lines
________ are short dashed lines. They show the edges of an object that is hidden from view by surfaces closer to the viewer
Hidden lines
________ are thin, alternating long and short dashes that are generally used to show hole centres and centre positions of rounded features, such as arcs and radii
Centre lines
________ and ________ are thin, solid lines that show the direction, length, and limits of the dimensions of a part
Dimension and extension lines
________ show information such as dimensional notes, material specifications and process notes
Leader lines
________ are used to show alternate positions for moving parts, the positions of related or adjacent parts and to eliminate repeated details
Phantom lines
________ show the location and path of imaginary cuts made through parts to show internal detail
Cutting plane lines
________ indicate the surfaces in a sectional view as they would appear if the part were actually cut with the cutting plane line
Section lines
________ are drawn to show that a part has been shortened to reduce its size on the drawing
