Yep, to celebrate the release of Autodesk Softimage 7.5 (I still can't believe I'm writing those words :( ) I've recompiled the famous dxf import and sunpath plugins for AD's newly acquired 3d package. (Eggh!) I will continue to update this plugin until AD add these features to the program or make Softimage to expensive to upgrade - I'll release the source code in that case.
You can get the dxf importer (plus most other versions) here.
You can currently get the new sunpath plugin here. At time of writing, nothing has changed except compatability with v7.5.
