Using Pipe Relationships
The general process of using a pipe relationship is as follows:
-
Define the pipe relationship between mating pipe/fittings.
-
Align the pipes using traditional relationships, pipe relation- ships, or a combination.
-
If the pipe relationship can find a valid cut plane, the pro- posed cut can be made. A frame can also be constructed on this cut for layoff purposes.
-
After physically cutting one end of the pipe, the actual cut plane can be fed into the solution, re-solving for a tweaked cut plane on the other end.
-
This tweaked cut plane can then be used to cut the mating piece.
