Saving 3D Models in RockWorks Posted April 5, 2012 I forgot to mention that your client can download and use our RockPlot3D stand alone program which is free and available from our website. Thanks for the response. I will see if they wouldn't mind doing that, or if they can accept a figure that doesn't rotate in PDF Side question on a similar note. Is the .r3dxml the only file path you can save 3D models or can they be saved so that they can be viewed on arc (or is arc compatible with the .r3dxml documents)? Oskar.
