The following error message appears when opening drawing files from Chapters 4, 5, 12, 13, 14, 15, 17, 18, 19: "Drawing file was created by an incompatible version."
The files are incompatible because many of them were created with a pre-release of the product used for testing, which isn't compatible with the final release. Our authors and technical editors checked all the files to make sure nothing had changed between pre- and final releases; however, if there were no changes, many times the files were not resaved in the final release. This causes the problems we are encountering. Fortunately, there is an easy solution.
Rather than supplying all of the corrected files, we are instructing readers to recover the files. This is very simple to do and takes a lot less time than downloading files.
Instructions for recovering drawing files:
1. Type "RECOVER" at the AutoCAD command line. A Select File dialog box appears.
2. Select the drawing to be used. AutoCAD will automatically recover it.
3. Resave the recovered drawing. From this point on, the file will open as a compatible drawing.
If the RECOVER command discussed above does not correctly restore the files, you can download replacement files (in Zipped format) below.
