Hi,

No. As fro every file that can be displayed on screen: as long as you can display the file there is no protection to avoid a screenshot.

Aside from screen shots, yes it is. In fact, that was what PDFs were originally designed for. You need to make a raster PDF. It will just be a pretty picture. Can that picture be converted so that text is searchable? Yes, there are ways around it because technology has gotten so good.

You could also look into secure PDFs. There are a number of levels of security.

Hi @martin.mardikas,

Against screenshots - no as @Alfred.NESWADBA said..

Plotting it as raster gives a pretty much similar result if the resolution was low..

Pdf plotters differ in their drivers, the ones that come with AutoCAD don't provide password protection..

The ones that Adobe provides (Adobe PDF printer driver) provide password protection and you can decide what others can and can't do with the file, you can disable copying - selecting - searching - printing...

Plotting to raster can have high resolution. It is a viable solution to the OPs question. Vector PDFs have not been around that long. I've plotted many raster PDFs that in turn plotted just as good as plotting the DWGs directly.

I realize that plotting to raster can give high resolution, but if it did it would be easy to use OCRs to convert them back to vector which we were trying to avoid in the first place.. Of course it will never be like the original, but still.. 

300 DPI & higher can be easily converted..

There are a lot of raster to vector converters in the market like Corel's built in OCR - and Raster2Vector... And why go so far? Autodesk itself has its solutions:.. 

Your suggestion to look into secre PDFs is a more viable option in my opinion..
