With the latest ProjectWise Design Integration Server v10.00.03.299, you can create a multi-page PDF from sheet\design models in a single file with doc set. In the past, you will have to create an InterPlot Set file (.ips) with InterPlot Organizer. Not any more, here's how.
a. In ProjectWise Administrator, 'Renditions - Rendition Profile Components - Output Formats - PDF', tick ON the option 'create one multi-page PDF for each flat set'
b. Configure InterPlot settings file, in 'Area' tab, enter 'IP_SHEETDEF_MODELS' in 'Search Models'
*Note: add 'IP_DESIGN_MODELS' when pages from design models are also required
c. create a doc set contains the DWG\DGN
d. create PDF rendition from the doc set
