Force Design Review to open PDF files using Vector information

If you open PDF files using the embedded vector data (ie. lines), you can then use ADR (Autodesk Design Review) to snap to PDF lines in order to measure them.

This may be useful to you if you are using ADR for markup tasks.  In our office, we are still very much PDF-centric, and various PDF readers allow you to measure PDFs anyway, so ... you get the idea.

If you want to force ADR to open PDFs as vectors, follow the steps on the following post at RevitForum:

Thanks to Tim West for the post, the training guide and the registry tweak.  Nice job!
