1.) PDF file sizes are huge -- email, FTP, printing, and viewing are cumbersome.
2.) No support for lines merge -- PDF files created will NOT view or print exactly as they would from AutoCAD.
3.) Doesn't convert True Type Text as searchable text in the PDF -- reduces the utility of the PDF.
4.) True Type Text comes out thicker than it should -- PDF will not print correctly.
5.) Can't create PDF's from any other application other than AutoCAD.
AutoCAD 2007 and 2008 does include PDF output by means of a '' DWG to PDF.pc3 '' plotter. After doing some investigating and analysis we have determined that the file sizes, PDF accuracy, utility, and ease of use will leave the CAD User looking for something more robust for their PDF output needs.
The AutoCAD 2007 '' DWG to PDF.pc3 '' plotter creates PDF files that are not text searchable in Acrobat® Reader®. Although a user selects landscape rotation when previewing and plotting the resulting PDF file is still incorrect for orientation.
Lines merge support in PDF's is when overlapping lines, hatch patterns, and solid fills are transparent. This function is not supported in the AutoCAD 2007 PDF output meaning that the PDF files created will NOT view or print exactly as they would from AutoCAD.
Controls for selecting what to plot or convert to PDF are limited to the AutoCAD 2007 plotting and publishing interfaces. Converting DWG files to PDF requires additional settings that are simply not found in the '' DWG to PDF.pc3 '' plotter.
The PDF file sizes are very large when compared to other software applications that convert DWG files to PDF. One D-size drawing is any where from 800KB to 3.1MB in file size when plotted to PDF from AutoCAD 2007. Multiply this file size buy the number of sheets in a design set and emailing, printing, viewing AutoCAD 2007 PDF's becomes a very painful task. Detailed file size comparisons are listed below.
The basic functionality the AutoCAD '' DWG to PDF.pc3 '' plotter has simply doesn't meet all the CAD User's needs. On most projects there are other file types like PLT, TIFF, CALS, DOC, XLS, that are included in the project set. Companies need a PDF software application that is capable of supporting these file types as well as the ability to create a PDF from ANY Windows application in order to remain competitive and efficient.
We have tested AcroPlot Pro, Adobe Acrobat 7.0, and AutoCAD 2007 with several files to determine the file sizes provided below. All the DWG files were output at 300 dpi. Typically the Wilhome.dwg file that is included with AutoCAD 2002 is good for testing because it can be used to test with all versions of AutoCAD. Although the Wilhome.dwg is a sample file, Autodesk has made some modifications to it over the years. Thus, we have provided the file size results for each version released.
