Parallel Line Pattern Development
17 Off Centre 90 Degree Tee
- Draw a full front elevation view and end elevation view.
- Draw profiles on the tee in both views and divide into 6 equal parts (see Divide a Circle Into 12 Equal Parts). Include all labeling. Remember that the labeling will flip with the view.
- Draw in the element lines from the profile divisions.
- Where the element lines hit the pipe in the end view, project them horizontally into the front view.
- Following the labeling, draw in the miter line in the front view.
- Draw the tee stretch-out and divide into 12 equal parts (see Divide a Line Using a Ruler on an Angle). Label the stretch-out to match the elevation view.
- Transfer/project the corresponding points from the front elevation view to the stretch-out.
- Circle the points and use a flexible curve to complete the pattern.
