Normally the sheet numbers are only shown on line continuations but not on branch connections when running ISOGEN Batch (IGB).

There are some organizations that are using a modified line number internally so as to denote the sheet numbers of continuations.

This involves adding a User1 field to the default line number, and either with the drop down setup or manually adding "-Sheet 1, -Sheet 2, etc.". Then the designer can designate the sheet numbers for the line(s) (either with Stop Signs or natural brakes).

If the models are to be turned over at the end of the project, to a client or others downstream, the line numbers would need to be reset to the default (i.e. removing the additional User 1 values).
