Solidworks导出eDrawings格式的文件后，怎么打开这个文件？我发现SW和AutoCAD都没法打开。

当您导出DWG文件后无法打开时，可能是由于以下原因导致：

1. 版本兼容性问题：DWG文件是由AutoCAD软件创建和使用的，不同版本的AutoCAD可能会有不同的文件格式和兼容性。如果您尝试打开的DWG文件是由较新版本的AutoCAD创建的，而您使用的CAD软件版本较旧，可能会导致无法正确打开文件。请尝试将CAD软件更新到最新版本，或者请导出为较旧版本的DWG文件再尝试打开。

2. 文件损坏：在导出过程中或储存过程中，DWG文件可能会出现损坏，导致无法打开。您可以尝试使用DWG文件修复工具，如AutoCAD的工具或第三方修复工具，来修复文件。另外，还可以尝试通过备份文件或联系创建文件的人来获取另一个可用的DWG文件副本。

3. 其他文件相关问题：有时，可能出现一些与导出或保存相关的其他问题，如文件路径过长、文件名含有特殊字符等。请确保导出和保存DWG文件时遵循软件和系统的要求，以避免这些问题。

如果您尝试了以上方法后仍无法解决问题，建议您联系CAD软件的技术支持团队或相关专业人士，提供详细的错误信息和文件，以获取更专业的帮助和解决方案。

How to export a model from SolidWorks to Google SketchUp
While Google SketchUp is not a professional CAD tool it has the advantage of being free and, because of that, it is used by a large number of people. Recently, some of my customers were asked by their own customers to supply SolidWorks models for review in SketchUp format.
There is one problem with this request – none of file formats that SolidWorks can export to are on the SketchUp import list. There are commercial converters from SolidWorks to SketchUp but they come at a cost.
SolidWorks to Google SketchUp Process
Fortunately, we found a way to exchange data between SolidWorks and SketchUp – just follow this workflow:
1. Save your SolidWorks model as ACIS (.SAT extension).

Save as ACIS
Note: Make sure that the Options are set as per this image:

红色箭头内容分别是实体/曲面几何体和版本10.0
Save As Options
2. Open DraftSight. If you have not installed this free 2D Editor, please use this link for doing so: Download DraftSight
3. In DraftSight’s command line type: “IMPORTSAT” and press <ENTER>. Locate the ACIS file you saved at step #1 and import it in DraftSight.

Import the ACIS file into DraftSight
4. Save this file again in DWG format.
5. Open SketchUp
6. Import the DWG file you saved at STEP #4.

Import DWG into SketchUp
7. That’s all. You have successfully imported your SolidWorks model into SketchUp.

Congratulations! You did it!
