I use Rhino to manage plan drawings and create abstract 3d representations for a subsequent simulation.
Most of the time I only get a PDF version instead of the requested DWG/DXF. Not a real problem as Rhino is able to read PDF as well…
…but while this ran smoothly in the past, most PDFs I try to open in recent times fail to do so. All I get ist an error message stating “… bad reference”
I usually open the PDF in Illustrator, convert to DWG and open that in Rhino. But that’s really just a crude workaround.
Please improve the error handling for opening PDF’s. I’m sure, there’s a lot of stuff that can’t be rendered in Rhino and needs to be ignored but that should not result in a single unspecific message and total refusal to open.
