When the pipeline for generating found only tutorial example of the basic development of secondary elbow, then I add a generation example of the three-way and four-way.
Generating easiest bend, the book has tutorials, and generates lower bend angle requirements.

Took a three-way, three things most important to note angle! ! angle! ! angle! ! , Perpendicular to the second tubes of the first tube should not exceed 1 °! Very strict!
There are primary and secondary order problem. As with the three-way ball valve insulation is required using the following protocol

4 is the final pass, the problem is still to be noted that the angle, and the connection parameters, the first parameter and the second common line, the third and fourth parameters collinear (i.e., the same line)
