最近客户拿来电子版图纸，我感觉不是cad图纸，每次打开都会出现一个对话框 ，显示：此dwg 文件由非autocad开发或许可的软件应用程序保存，autocad不能保证应用程序兼容性或文件完整性。继续/取消  详细信息单击此处。
点击 “详细信息单击此处”，出现如下信息：
7 ]" S, i* o' v) u4 ]" MWhat Is TrustedDWG?
Developed by Autodesk, and comprising the core file format for AutoCAD? software and AutoCAD-based products, DWG? technology is the original, efficient, and accurate way for storing design data created using AutoCAD and AutoCAD-based products. With DWG files circulating throughout virtually every design industry, DWG technology has made the DWG file format one of the most commonly used design data formats. 

AutoCAD? 2007, AutoCAD? 2008, and AutoCAD? 2009 software include TrustedDWG functionality. At the option of the user, the software will notify users when the DWG file they are opening was saved using an application that was not created by an Autodesk product or RealDWG? software licensee. This identifies files that Autodesk may not be able to support and alerts the user that Autodesk cannot guarantee the integrity or compatibility of that DWG file with AutoCAD or any other Autodesk application. Much like functionality that allows Internet users to choose which files they download from the Internet, TrustedDWG does not repair defects or identify or correct integrity or compatibility concerns that may exist in the file, but enables the AutoCAD user to choose whether or not to use DWG files that were not last saved by an Autodesk or RealDWG licensee product. The TrustedDWG notification may be easily disabled by checking the box identified for that purpose.

出现这个提示是因为好些dwg格式的文件不是在cad创建的。比如 cd和ai之类的软件，他们虽然是dwg格式的～但是或多或少有一些不兼容吧，特别是一些其他软件的专有特性，在cad中可能体现不出来，如果你要用这个dwg 不用管他直接打开就好
