在Autodesk网站上找到原因了,看来不是破解的问题
What is Trusted DWG?
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 the world’s most commonly used design data format.
AutoCAD 2007 software introduces Trusted DWG functionality. As part of our ongoing testing, support calls, and Error Reporting we’ve received, we recognized that DWG files that have been edited or saved by non-Autodesk® or non-RealDWG™ applications may cause data corruption and application stability issues when used with AutoCAD products. At the option of the user, AutoCAD 2007 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 licensee. This will help to protect a customer’s DWG data from corruption and give users warning that the DWG file they are opening may cause stability issues. Much like functionality that allows internet users to choose which files they download from the Internet, Trusted DWG does not itself repair defects in the file that may exist but enables the customer to choose whether or not to accept risks that may be associated with DWG files that were not last saved by an Autodesk or RealDWG licensee product.
Continuously innovated and re-engineered to allow for powerful new design productivity in Autodesk software, only Trusted DWG maintains the integrity and reliability of your data. |
