I want to see if a pdf file has geographic data and how to access them. In the properties of the PDF document I see the pdf file was made in "AutoCAD Map 3D 2013," and have 6 layers.
In QGIS 2.14, when I add a vector layer, appears only 3 layers and the attribute tables only show the ID field. I read somewhere that something must be processed first to see more data but I can´t find it anymore.
It is true that to see more data is required to use some command in QGIS or process something?
