Multi-sheet Store Layout sets, about 1 MB 400 DPI, grew by 10–20%. Publishing a 20 sheet drawing set for our office (Site, Building, Fit-out Plans and Elevations) with lots of hatch fills resulted in the file growing from 2.5 MB 400 DPI to 3.0 MB DPI. It was a bit of a concern that the file size nearly doubled but it seems this is because the initial file was so small. The table below shows the results using the DWF6 ePlot.pc3. The file has a lot of AEC Mv Blocks (shop fittings) and AEC Spaces (departments) with solid hatch fills. For a real world comparison I created a DWF from a store layout at various resolutions then measured a known length in Autodesk Composer aiming for better than 1mm precision. ![]() ![]() ![]() We draw on A1 sheet at 1mm = 1 AutoCAD unit typically with a 1:200 viewport. So far I’ve found ramping the DPI up to fairly huge values does increase the DWF file size, but not as much as I expected, and seems to have only a slight impact on plot file sizes. Prompted by Shaan's post on DWF precision I’ve been testing to see what impact increasing the DPI has in “real world” conditions.
