Section 3 of the report, Tracing Data is a record of the actions the software is taking in building the internal data structure of the piping network. This section is primarily useful to Intergraph for investigating software problems.

The last statement in section 3 states how many disconnected sections of piping exist in the network identified in the database search criteria. If the number of sections is greater than 1 then the line is not extracted and the intermediate data file is not generated. ISOGEN does not allow multiple, disconnected sections of piping to be extracted into a single iso.

The following is a list of possible reasons why a network might be disconnected and some suggested solutions:

  1. The database search criteria identified more than one pipeline and the pipelines are not connected together. The solution here is to change the search criteria so that only the piping that you really want to extract is pulled in.

  2. The pipeline being extracted is incomplete and portions of it do not have components on it. The solution is to place all of the components on the line.

  3. Although the line is finished, there is a part of it that appears to be connected, but is not. For a line to be considered connected the connect points from two different components must be within 20 uors of each other.

In this case you should examine section 2 of the HITS report to find a connect point whose node number is -1 (which indicates that it is a line endpoint) even though you know it should be connected to something. This is usually quite simple when the line is small. When you find the connect point, use the coordinate to view and repair the disconnected graphics. When the line is complicated, you can use section 4 of the HITS report (see the section Tracing Data) to make a sketch that identifies the disconnected point.
