My potential client uses an engineering program called solid edge, which exports in the following formats :igs .jt .sat .stp .x_b .x_t .xgl .plmxml .bkm .asm he did an animation (solid colors) with the complete machine, we now want to make it more "marketing oriented" and need to upgrade the rendering, hence we want to bring it into carrara3 (thats what I use)....any experience out there with the above formats? and how to bring it into carrara?
