Radial Line Pattern Development
- 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.
