Hi Everyone,

I am posting this question here in another thread, since this seems to be a somewhat different topic than before. Hope I am going about this correctly =)

Earlier I asked about extruding cartoons and hand-drawn images in MoI. Many wonderful contributions, but somewhere along the lines, I missed out on the basic steps of how to get MoI usable files such as EPS. I'm still learning MoI. I know how to extrude MoI created solids but am unsure about how to handle "outside created" stuff.

Can someone help explain step-by-step, or link me, to a summary of how to get MoI supported files to extrude?
