Specifies how branch error and coordinate prompts display. You are prompted for two pieces of information:

  • The loop closure tolerance.

  • The global coordinates of the first point of the piping system and each following piece of the piping system that is not connected to the first.

This data is needed the first time CAESAR II prepares a global geometry calculation. This calculation is made on three different occasions:

  • Before preprocessor plots are generated.

  • Before global coordinate reports are built.

  • Before error checking is performed.

Alternatively, you can select Edit > Global and specify the global coordinates to avoid any prompting.

There are several major uses for this flag:

  • Set the loop closure tolerance.

  • Define the elevation of the piping system for wind/wave load calculations.

  • Give the proper east-west or north-south coordinates for dimension checks.

  • Move parts of the system around in the plotted output for visual checking.

Whenever you create a physical loop in the piping system, there are at least two different sets of dimensions between the same points. If the two dimensions are not within a certain tolerance of each other, a fatal error occurs. You can set this tolerance interactively or in the configuration file. Select Both for the Branch Error and Coordinate Prompts option to cause CAESAR II to interactively prompt for this tolerance.
