  1. DRAWING A HELIX/SCREW THREAD HELIX = SPRING SPIRAL = FLAT

  2. Major Diameter – Largest diameter of the thread Major Diameter

  3. Thread Pitch – Distance between any two of the same points of a thread Thread Pitch

  4. 3 1 2 REGENERATE CYLINDER TOP PLANE Ø2.00 HEIGHT 5 SKETCH A CIRCLE SAME DIAMETER AS THE CYLINDER 4 5 REGENERATE AGAIN FEATURES: CURVES, HELIX & SPIRAL

  5. CLICK THE CIRCLE 7 6 PITCH & REVOLUTION ADJUST PITCH OF HELIX ADJUST HELIX REVOLUTIONS (TURNS) 8 TILT VIEW OF CYLINDER TO SEE END OF THE HELIX 9 FEATURES: REFERENCE GEOMETRY PLANE

  6. 2. CLICK THE END POINT OF THE HELX 10 1. CLICK THE LINE OF THE HELIX A NEW PLANE APPEARS AT THE END OF THE HELIX 11 VIEW NORMAL TO:
