3. (c) Introduction.

   1. (1) Career and technical education instruction provides content aligned with challenging academic standards and relevant technical knowledge and skills for students to further their education and succeed in current or emerging professions.
   2. (2) The Manufacturing Career Cluster focuses on planning, managing, and performing the processing of materials into intermediate or final products and related professional and technical support activities such as production planning and control, maintenance, and manufacturing/process engineering.
   3. (3) In Blueprint Reading for Manufacturing Applications, students gain knowledge and skills in an introduction to reading and interpreting working drawings for basic machining processes, mechanical maintenance, basic electrical, basic fluid power, and basic facility prints. Students also use sketching techniques to create pictorial and multiple-view drawings.
   4. (4) Students are encouraged to participate in extended learning experiences such as career and technical student organizations and other organizations that foster leadership and career development in the profession such as student chapters of related professional associations.
   5. (5) Statements that contain the word "including" reference content that must be mastered, while those containing the phrase "such as" are intended as possible illustrative examples.

      2. (B) explain the function of and use measuring devices such as scales, micrometers, and dial calipers;
      3. (C) explain and demonstrate basic functions of computer-aided design and drafting (CADD) software;
      4. (D) identify blueprint symbols, including surface profile, position, run out, countersink, and depth symbols;
      5. (E) differentiate between driving and reference dimensions;
      6. (F) identify basic electrical print symbols, including switch, lamp, relay, and contact symbols;
      7. (G) identify basic fluid power print symbols, including power unit, actuator, directional control valve, and flow control symbols;
      8. (H) identify various P&ID symbols, including valve, gauge, meter, and regulator symbols; and
      9. (I) identify symbols for components, including threads, fasteners, and springs, used in the manufacturing process.

   3. (3) The student interprets facility drawings related to manufacturing buildings. The student is expected to:

      1. (A) interpret and explain floor plan drawings;
      2. (B) interpret and explain elevation drawings;
      3. (C) interpret and explain section views and details;
      4. (D) locate electrical components, including distribution panels, lights, switches, and outlets, on facility drawings;
      5. (E) identify plumbing components, including drains, water supply, and boilers, on facility drawings; and
      6. (F) identify heating, ventilation, and air conditioning (HVAC) components, including condensers, evaporators, and plenum, in facility drawings.

   4. (4) The student applies drafting principles to create sketch pictorials and construct multi-view drawings. The student is expected to:
