GeoFrac & 3DStudio MAX
GeoFrac2000 does not directly support exporting into 3DS Max. However, since GeoFrac exports Rhino .3DM files, and since the McNeel crew have written 3DS Max import plugins for ALL version of MAX, I didn't see the need for me to write (or re-write) plugins for GeoFrac for all versions of MAX as well.
Thus, if you want to import GeoFrac mesh objects into 3DS MAX, all you need is the Rhino-MAX import plugin for your appropriate version of 3DS MAX. Then, just export meshes in GeoFrac to Rhino's 3DM file, and then import them into MAX using the Rhino-MAX plugin.
Here are the links to the different versions of the plugin:
Just pick the right plugin that matches your version of MAX, download it and place it in your MAX "Plugins" directory.
Please let me know if you have any problem.
Thanks,
Jeff.
