Parallel Line Pattern Development
15 Equal Diameter 90 Degree Tee
- Draw a full front and end elevation view (right side). Notice that the tee does not go passed centre of the pipe, it never will. Because of that, we can delete that portion of the drawing.
- Draw on the tee in both views and divide into 6 equal parts (see Divide a Circle Into 12 Equal Parts). Include all labeling. Keep in mind that the labeling will rotate 90° with the view.
- Draw in the from the profile divisions.
- Where the element lines hit the pipe in the end elevation view, project them into the front view.
- Following the labeling, draw in the line in the front view.
- Draw the tee and divide into 12 equal parts (see Divide a Line Using a Ruler on an Angle). Label the stretch-out to match the elevation views.
- Transfer/project the corresponding points from the elevation views to the stretch-out.
- Use a flexible curve to draw in the miter line, completing the .
