  1. Draw a full [pb_glossary id=\"532\"]plan view[\/pb_glossary]<\/strong> complete with all [pb_glossary id=\"527\"]element lines[\/pb_glossary] <\/strong>and labeling.

  4. Pick up the [pb_glossary id=\"539\"]true length[\/pb_glossary]<\/strong> of line A-4 and swing it from point A.\"\"<\/li>\r\n \t
  5. Next, pick up true length of line B-4 and swing it from point B. Where it crosses the first arc, becomes point 4.\"\"<\/li>\r\n \t
  6. Pick up a step-off from the plan view and swing it from point 4. Unlike an on-centre square to round, this fitting needs to be developed one side at a time. Complete one side, then go back to finish the other side.\"\"<\/strong><\/li>\r\n \t

  12. Pick up the true length of line D-1 and swing it from 1.\"\"<\/li>\r\n \t
  13. Pick up line A-D from the plan view (remember that letter to letter is true length) and swing it from point A. Remember that point D should be 90<\/strong>\u00b0. If it not, go back and check your work.\r\n\"\"<\/strong><\/li>\r\n \t
  14. Now, go back to point 4 and work the pattern to the other side, completing it at point C. Notice in this example, line C-7 has no length in the plan view, it is a dot. The true length is the [pb_glossary id=\"522\"]vertical[\/pb_glossary]<\/strong> height. Zero plan length put 90 deg to the vertical height, will have no change to the vertical height.\"\"<\/li>\r\n \t
