Spent a fair amount of energy convincing a large client to consider DWF as well as PDF's
After 12 months, they decide to give it a real go. Only problem was that the drawings they tested had ECW files attached (Using MAP to attach large scale aerial photographs) This is not unusual in Civil design study drawings etc.
The result we found is that DWF handles CAD + Raster images poorly compared to PDF.
Example: PDF file was approx 12MB, the DWF = 50MB. Youch. Our tech team asked Autodesk and their reply was unfortunately out of touch with the real world, and obviously without considering the problem. The AutoCAD file does not have the image 'inserted' therefore it is a small file. We had client test file without the raster images attached - it went down to about 1.5MB. Of course I understand that a DWF file is a vector format.
The response from Autodesk was disappointing in the extreme: "We recommend that users working with CAD formats consider DWF over PDF as their are many advantages etc etc" A sales spiel. Well for this client they ain't going to use DWF...
The least we should expect is that Autodesk improves the Raster handling and have a DWF file (using the above example) at say, sitting around 10-14MB. Otherwise in cases where clients need to attach raster images, they cannot utilise DWF formats.
