When trying to import a SKP file to use as a 3D marker symbol in either ArcGlobe or ArcScene, the file does not display. No error message occurs, but there is a message in the Symbol Properties dialog box beside the import button stating 'no geometry loaded'.
This is caused because the SKP file is version 5 or newer. ArcGlobe and ArcScene only import SKP files that are version 3 or version 4.
