I've put together some examples of CONNECT Reports, with instructions on how to define them. These were prompted by a need to find an alternative to MicroStation's venerable XYZ Text tool. As well as an XYZ Text Report example, I've added a Cell Report and a Linear Report example.
Each example shows step-by-step how the Report is defined, with examples of CSV file and Excel file output. You can download a ZIP file that contains the DGN file containing the Reports definitions and sample output data.
