We receive isometric of any line from piping layout group using PDS or Intergraph, split into number of sheets as pdf files . There are 2 scenarios during analysis-
1. system passes without routing change.
2. There are changes required to be made in route while passing the system in some part of the system.

I want to smartly export support symbols and support node numbers back to these PDF files at least to sheets which did not involve route change , I want to automate that process and not mark manually. Want to make in-house utility which uses CAESARIIs export facility to ACAD ( Not CADWORX , but ACAD , if such a facility is there now . If not, then export to CADWORX) . Also would need to use Bluebeam or some interface with pdf to export support nodes and support symbols from CAD file to pdf sheets. The problem is how CAESARII export facility to ACAD or CADWORX will co-relate itself to the way sheet splitting was done for generating isometric from line modeled in PDS or SP3 D ? How CAESARII can get that info from those split sheets ( pdf files). Is there any way CAESARII can get that info ? Co-ordinates would help ?
Can you throw some light ? That would be a great help.
