Re: Manipulation of DWF

Looks like you are aware of the accuracy aspect. So I am not saying anything new here....but I just want to point out that the comparison to anti-piracy efforts in DVDs is incorrect. The difference is that in DWFs accurate model information isnt hidden or protected - its just not there. So you can hack all you want but what you get will only be as accurate as whats in there. Even with prints and plots you can scan the hard copy output, pump it through a raster to vector converter and get vector information out. If the publisher wishes, DWFs can be made to be only as accurate as paper. -- Sriram Gopalakrishnan Autodesk

True but for what most people are trying to copy the DWF the accuracy is probably perfectly fine. Since DWF Composer can fairly accurately measure distances the accuracy is there for most uses. As Shaan points out basically the only way to secure your data is to not share it in the first place. I come from the mechanical background and why most people would want to convert a DWF to a DWG would be to drop the part that they are purchasing into an assembly or drop the machine into a plant layout. But in both these cases as with any case of converting something to DWG the user should be asking for (or requiring) a DWG in the first place instead of a DWF. -- Rodney McManamy President CADzation ------------------------- rmcmanamy@cadzation.com ------------------------- 518 South Route 31 Suite 200 McHenry, IL 60050 www.cadzation.com Providing Industrial Strength PDF & DWF Solutions to the Global CAD Marketplace.
