  5. Locate a radius point where you want to develop the pattern.\u00a0Unlike Parallel line, it doesn\u2019t matter where this is. There is no projection into the pattern like we used before.

  6. With your compass, take the [pb_glossary id=\"536\"]slant height[\/pb_glossary]<\/strong> from the elevation view and swing an arc ([pb_glossary id=\"537\"]stretch-out arc[\/pb_glossary])<\/strong>. Because we don\u2019t know how long the arc needs to be yet, we use best judgement. We do know that it will be equal to the base circumference. The shallower the cone is, the larger the stretch-out angle will be. A very steep cone will be a much smaller angle\"\"<\/strong><\/li>\r\n \t
  7. Establish a starting point for the pattern and draw a line back to the radius point. The starting point can be anywhere along the arc\"\"<\/li>\r\n \t
  8. Set your compass to a step-off. From your starting point, swing it 12 times along the stretch-out arc.\"\"<\/strong><\/li>\r\n \t
  9. Connect the last point back to the radius point to complete the pattern.\"\"<\/li>\r\n<\/ol>\r\nhttps:\/\/www.youtube.com\/watch?v=qhhtfGPvg0c","rendered":"
