Q: Some PDF files not open by Preview

Hi !

This is my problem:

1) Some PDFs couldn't be open by Preview.

2) However, it can be viewed at Finder view panel.

3) When I press spacebar on the PDF file, it can be viewed.

4) But when I double click the PDF file, the content is blanked.

5) This only happen when I receive the PDF files that created from AutoCAD.

6) When I open these files in Adobe Acrobat reader, I have no problem reading them.

7) I wish to open the file in Preview, so I can work on it. Couldn't do that in Acrobat Reader.

Any solution
