I have done a comparison between Acrobat 3D and Solidworks eDrawings. I must say I like eDrawings alot better. And I am a Pro/ENGINEER user. Much more simple than Acrobat 3D to figure out. All the controls are right there and straight forward in eDrawings. I have some users I work with I have asked to evaluate the files. One was another veteran CAD user and said he had some difficulties trying to do certain functions.
One example is you have to set up the explode view in Acrobat in a seperate module. Granted it comes with Acrobat 3D, but still much more difficult to create than in eDrawings. I never did figure out how to create one in the 30 trial period.
In eDrawings you have one button to create a cross-section and you can drag and drop the plane where ever you wanted. A little more involved in Acrobat.
As far as measuring goes, again, much easier in eDrawings. In Acrobat, you had to bring up this dialog box each time you wanted to add, delete or modify. eDrawings had the icon right there for you to use.
The best parts of eDrawings is you don't need to install ANYTHING for a non-eDrawings user to view a model and there is a free version. You can create an executable that includes its own viewer. If someone is worried about the file getting striped out of an email, just rename the file extension and have the person rename it back. With Acrobat, it had to be a certain version for an Adobe Reader user.
IMO, a better way to go is with eDrawings. Acrobat 3D: $995. eDrawings: $500 for the full vesion.
