Motionize development has taken a different path and this development version has adopted a different name: Vekpo. The ultimate delivery and interface method is still in testing but a preliminary offering is available on the Motionize Development page. It currently only works with iDraw/Graphic files.
Vekpo will rejoin Motionize on its official release but until then please feel free to offer suggestions and submit issues via email. Thanks for your patience!
The future of Motionize is to support a limited filetype input set including: iDraw/Graphic, SVG and PDF. Along with this native support (currently only iDraw/Graphic) will be an API for support of other formats.
