I'll post here if I get a reply from the people I've mailed... Corel, the former product responsible in Micrograpx and some other "gugus" lol. I tried to use Crossroads, but however I saved the S3d file as vrml, it reported errors, either in line 12 or line 2. sigh. It's a pitty, really.. because there are so many nice models in that pack.
