The manual for version 7 is on the product downloads now, in the top of our forum header and FAQ (https://www.renderosity.com/mod/forumpro/?forum_id=12459&show_faq), and on our blacksmith3d.com support page (https://www.blacksmith3d.com/news.php?viewStory=60). I have pasted the link here to the manual for your convenience: https://www.blacksmith3d.com/files/Blacksmith3D-Manual-v7.pdf.

Typically, you should export as an obj. You can try doing the export as a DUF file, but there isn't a direct export to Daz Studio.
