Center Line Center line should be thinner than object/hidden line. Leave space when meeting object/hidden line Phantom line Continuous center line

Hidden lines should join other hidden lines. Hidden line should join object line, except when it appears like an extension of the object line. Hidden lines should join other hidden lines.

Hidden Lines Parallel hidden lines should be staggered. Hidden lines should join other hidden lines.

Curved Hidden lines should join Center line. Hidden line should join object line, except when it appears like an extension of the object line. Curved Hidden lines should join Center line.
