Radial Line Pattern Development

# 23 Cone on a Pitch/Miter

- Draw an , including the
**point**. - the base of the elevation view and divide it into six equal parts.
- Label the profile from 1 to 7 and project the divisions vertically into the base of the cone.
- Project the from the base to the apex of the cone.
- Draw in the
**line**.

- Where the element lines cross the miter line, project them horizontally to the outside edge. This now creates seven different slant heights.

- Locate a radius point where you want to develop the pattern.
- With your compass, take the large and swing an arc.
- Set your compass to all of the remaining slant heights and swing them from the radius point.
- Establish a starting point for the pattern and draw a line back to the radius point.
- Set your compass to a step-off. From your starting point, swing it 12 times along the and label each point to match the elevation view.
**Start your numbering where you want the seam, commonly put on the short side of the cone.** - Connect the all of the points back to the radius point.
- Following your numbering, circle each intersection point.
**This will create the pattern of over 1, down 1.** - Use a flexible curve to connect the points and create the pattern.
