Accepting Differences

Integrator allows a designer to accept differences from the comparison report, for situations where the 3D and schematic models have a different level of detail, or are functionally equivalent but do not match precisely. Examples include vent and drain detail, instrument connections, and welded attachments. Note that Integrator automatically ignores MDS trunnions, but trunnions defined by other means may still be included in the comparison and so could be handled as described below.

The differences can be accepted and managed in the following ways, and will not be flagged up thereafter in the comparison report:

1. Accept Differences: A pair of linked objects having differences such as attribute values, sizes, connections or sequence, can be accepted as different.

2. Accept Missing Element: For unmatched objects, such as a drain connection, the corresponding elements can be accepted as missing. Integrator will still match the object if it is added subsequently to the model.

3. Disable Matching: For objects that should not be matched ever, such as a tee for a trunnion, whether or not Integrator has currently matched them, matching can be disabled.

All of these actions can be reversed and the differences will then revert to being flagged up in the comparison report. Once a number of differences have been accepted it is necessary to redo the comparison in order to see the effects. This in turn can change which objects are matched and thus offer more opportunities to accept differences, and so the process may take several cycles to achieve the desired results.
