4 Oblong Elbow
- Using the elbow rule, calculate the miter angle of the elbow
- Using trigonometry, calculate the seam height of the end gore. The seam height can be used to calculate the height of the blank size as normal
- Draw a complete elevation view of 1 end gore, complete with profiles, element lines, and labeling. An oblong can go in 2 directions, with the longer dimension either being visible in the elevation view or not. If it not visible in the elevation view, be sure to include it correctly in the profile
- Calculate the stretch-out and draw the blank size directly to the right of the elevation view
- Divide the stretch-out according to the perimeter of the gore and label accordingly. There will be straight sections and round portions.
- Project the element lines from the miter line to the blank size
- Find the corresponding points and complete the pattern
